Here is what could be a nice option for Anamorphic on the FX9 (or any other Super 35mm capable camera. The new Sirui 24mm 1.33x anamorphic lens. I have not tried these yet, but at only $999 or $749 with the early bird offer it’s certainly an affordable way into the world of Anamorphic. 1.33x lenses are designed to provide a final aspect ratio of 2.40:1 when used with a 16:9 sensor. Here’s the info from the press release.
SIRUI launch 24mm F2.8 1.33x anamorphic lens in Micro Four Thirds, Sony E, Canon EF-M, Nikon Z and Fujifi?lm X Mounts
New wide-angle anamorphic optic from SIRUI revolutionizes affordable cinematography
NEW YORK, January 4, 2021 – SIRUI have today introduced a groundbreaking new 24mm F2.8 1.33x lens that redefines what is possible from a wide-angle anamorphic optic. It features the beautiful stretched oval bokeh and streaked lens flares that Sirui’s affordable anamorphic lenses have become known for, combined with a new wider field of view.
Options for affordable wide anamorphic shooting have been very limited until now. Traditional wide-angle anamorphic cinema lenses have cost tens of thousands of dollars, while DIY anamorphic adapters based on optics designed for projection don’t cover wider angles. In addition, most of these solutions have limited close focus.
The SIRUI 24mm F2.8 is designed from the ground up to address these needs. The lens features a 1.33x squeeze factor and has an imaging circle that covers APS-C sized sensors. It is available in native mounts for Micro Four Thirds, Sony E, Canon EF-M, Nikon Z, and Fujifilm X cameras and is sturdily built with an all-metal body. Front filter size is 77mm and the lens barrel is non-rotating which allows for easy use of variable ND and other filters. With persistent efforts, the SIRUI R&D team resolved key technical problems to deliver a previously impossible 0.6m minimum focusing distance – all without the need for additional diopters.
The fast F2.8 aperture of the 24mm lens allows foreground objects to stand out against smoothly blurred backgrounds and night scenes to be perfectly captured. Combining the fast aperture with the 0.6m close focus also makes for interesting close-up options.
The SIRUI 1.33x Anamorphic line-up consists of 24mm, 35mm and 50mm lenses.
The new 24mm joins the company’s existing 50mm and 35mm 1.33x anamorphic lenses to form a set of lenses that share common aesthetics and handling. Cinematographers can now use the lens trio to tell complete cinematic stories with SIRUI’s signature look, switching freely between scenes while maintaining common background rendering.
Sirui lenses truly enhance the artistic appeal of your footage and immerse your audience in an anamorphic world.

Last week I was at O-Video in Bucharest preparing for a workshop the following day. They are a full service dealer. We had an FX9 for the workshop and they had some very nice lenses. So with their help I decided to do a very quick comparison of the lenses we had. I was actually very surprised by the results. At the end of the day I definitely had a favourite lens. But I’m not going to tell you which one yet.
The 5 lenses we tested were: Rokinon Xeen, Cooke Panchro 50mm, Leitz (lecia) Thalia, Zeiss Supreme Radiance and the Sony 28-135mm zoom that can be purchased as part of a kit with the FX9.
I included a strong backlight in the shot to see how the different lenses dealt with flare from off-axis lights. 2 of the lenses produced very pronounced flare, so for those lenses you will see two frame grabs. One with the flare and one with the back light flagged off.
I used S-Cinetone on the FX9 and set the aperture to f2.8 for all of the lenses except the Sony 28-135mm. For that lens I added 6dB of gain to normalise the exposure, you should be able to figure out which of the examples is the Sony zoom.
One of the lenses was an odd focal length compared to all the others. Some of you might be able to work out which one that is, but again I’m not going to tell you just yet.
Anyway, enjoy playing guess the lens. This isn’t intended to be an in depth test. But it’s interesting to compare lenses when you have access to them. I’ll reveal which lens is which in a couple of weeks in the comments. You can click on each image to enlarge it.
Big thanks to everyone at O-Video Bucharest for making this happen.
Below is a list of lenses that have been tested with the FX9’s advanced autofocus system. Generally any Sony E-mount lens will work just fine. The Sony G series lenses are good and the G Master series tend to be even better. For third party lenses and adapters the situation is much less clear, so I have decided to list the lenses I have tested and invite others to contribute to this list via the comments area. The list is not exhaustive at this time but I will try to keep adding to it as I am able to try more lenses and and different adapter combinations.
Inclusion of a lens on this list is not a guarantee that it will or will not work, it is simply an indication of how it worked for me or anyone else that adds information about their own experiences. I welcome updates and any further information from any lens or adapter manufacturer.
If there is a lens you have tested on an FX9 please let me know via the comments how it worked so it can be added to the list.
KNOWN TO WORK WELL:
Sony E (super 35mm) FE (full frame) lenses, G and G-Master including Zeiss ZA series. G and G Master tend to have the best AF performance.
Tamron 28-75 f2.8 Di III RXD E-mount.
KNOWN TO WORK, BUT NOT AS GOOD AS ORIGINAL SONY:
Sigma 20mm f1.4 ART with Sigma MC11 adapter. Works, but a little slow and occasionally hunts.
KNOWN TO NOT PERFORM WELL:
Sigma 20mm f1.4 ART native E-mount (very slow AF, hunting, contrast only?).
Sigma 85mm f1.4 ART native E-mount (very slow AF, a lot of hunting).
Sigma 20mm f1.4 ART Canon EF mount on metabones, comlite or viltrox adapters. Very slow AF, not really useable.
If you are starting to think about lenses to take advantage of the FX9’s amazing autofocus capabilities then you should know that I have tested quite a few different lenses on the FX9 now. I have yet to find a Sony lens where the AF hasn’t worked really well. Even the low cost Sony 50mm f1.8 and 28mm f2 lenses worked very well. Infact I actually quite like both of these lenses and they represent great value for the money.
But what I have found is that non Sony lenses have not worked well. I have been testing a range of lenses on various pre-production cameras. Maybe this situation will improve through firmware updates, I would hope so, but I honestly don’t know. The E-mount Sigma 18-35 and 20mm art lenses I tried were not at all satisfactory. The AF worked, but in what appears to be a contrast only mode. The autofocus was much slower and hunted compared to the fast, hunt free AF with the Sony lenses. You would not want to use this which is a great shame as these lenses are optically very nice.
It’s the same story when using Canon EF lenses via both Metabones and Viltrox adapters (I have not tested the Sigma MC11). Phase AF does not appear to work, only contrast and it’s slow.
So if you are thinking about buying lenses for the FX9 the only lenses I can recommend right now are Sony lenses. Don’t (at this stage at least) buy other brand E-mount lenses or expect lenses to be used via adapters unless you can find a way to test them on an FX9 first.
There is something very special about the way anamorphic images look, something that’s not easy to replicate in post production. Sure you can shoot in 16:9 or 17:9 and crop down to the typical 2.35:1 aspect ratio and sure you can add some extra anamorphic style flares in post. But what is much more difficult to replicate is all the other distortions and the oval bokeh that are typical of an anamorphic lens.
Anamorphic lenses work by distorting the captured image. Squeezing or compressing it horizontally, stretching it vertically. The amount of squeeze that you will want to use will depend on the aspect ratio of the sensor or film frame. With full frame 35mm cameras or cameras with a 4:3 aspect ratio sensor or gate you would normally use an anamorphic lens that squeezes the image by 2 times. Most anamorphic cinema lenses are 2x anamorphic, that is the image is squeezed 2x horizontally. You can use these on cameras with a 16:9 or 17:9 super35mm sensor, but because a Super35 sensor already has a wide aspect ratio a 2x squeeze is much more than you need for that typical cinema style final aspect ratios of 2.39:1.
For most Super35mm cameras it is normally better to use a lens with a 1.33x squeeze. 1.33x squeeze on Super35 results in a final aspect ratio close to the classic cinema aspect ratio of 2.39:1.
Traditionally anamorphic lenses have been very expensive. The complex shape of the anamorphic lens elements are much harder to make than a normal spherical lens. However another option is to use an anamorphic adapter on the front of an existing lens to turn it into an anamorphic lens. SLR Magic who specialise in niche lenses and adapters have had a 50mm diameter 1.33x anamorphic adapter available for some time. I’ve used this with the FS7 and other cameras in the past, but the 50mm diameter of the adapter limits the range of lenses it can be used with (There is also a 50mm 2x anamorphot for full frame 4:3 aspect ratio sensors from SLR Magic).
Now SLR Magic have a new larger 65mm adapter. The 1.33-65 Anamorphot has a much larger lens element, so it can be used with a much wider range of lenses. In addition it has a calibrated focus scale on it’s focus ring. One thing to be aware of with adapters like these is that you have to focus both the adapter and the lens you are using it on. For simple shoots this isn’t too much of a problem. But if you are moving the camera a lot or the subject is moving around a lot, trying to focus both lenses together can be a challenge.
Enter the PD Movie Dual Channel follow focus.
The PD Movie Dual follow focus is a motorised follow focus system that can control 2 focus motors at the same time. You can get both wired and wireless versions depending on your needs and budget. For the anamorphic shoot I had the wired version (I do personally own a single channel PD Movie wireless follow focus). Setup is quick and easy, you simply attach the motors to your rods, position the gears so they engage with the gear rings on the lens and the anamorphot and press a button to calibrate each motor. It takes just a few moments and then you are ready to go. Now when you turn the PD Movie focus control wheel both the taking lens and the anamorphot focus together.
I used the anamorphot on both the Fujinon MK18-55mm and the MK50-135mm. It works well with both lenses but you can’t use focal lengths wider than around 35mm without the adapter some causing vignetting. So on the 18-55 you can only really use around 35 to 55mm. I would note that the adapter does act a little like a wide angle converter, so even at 35mm the field of view is pretty wide. I certainly didn’t feel that I was only ever shooting at long focal lenghts.
Like a lot of lens adapters there are some things to consider. You are putting a lot of extra glass in front of you main lens, so it will need some support. SLR magic do a nice support bracket for 15mm rods and this is actually essential as it stops the adapter from rotating and keeps it correctly oriented so that your anamorphic squeeze remains horizontal at all times. Also if you try to use too large an aperture the adapter will soften the image. I found that it worked best between f8 and f11, but it was possible to shoot at f5.6. If you go wider than this, away from the very center of the frame you get quite a lot of softening image softening. This might work for some projects where you really want to draw the viewer to the center of the frame or if you want a very stylised look, but it didn’t suit this particular project.
The out of focus bokeh has a distinct anamorphic shape, look and feel. As you pull focus the shape of the bokeh changes horizontally, this is one of the key things that makes anamorphic content look different to spherical. As the adapter only squeezes by 1.33 this is as pronounced as it would be if you shot with a 2x anamorphic. Of course the other thing most people notice about anamorphic images is lens flares that streak horizontally across the image. Intense light sources just off frame would produce blue/purple streaks across the image. If you introduce very small point light sources into the shot you will get a similar horizontal flare. If flares are your thing it works best if you have a very dark background. Overall the lens didn’t flare excessively, so my shots are not full of flares like a JJ Abrams movie. But when it did flare the effect is very pleasing. Watch the video linked above and judge for yourself.
Monitoring and De-Squeeze.
When you shoot anamorphic you normally record the horizontally squashed image and then in post production you de-squeeze the image by compressing it vertically. Squashing the image vertically results in a letterbox, wide screen style image and it’s called “De-Squeeze”. You can shoot anamorphic without de-sqeezing the image provided you don’t mind looking at images that are horizontally squashed in your viewfinder or on your monitor. But these days you have plenty of monitors and viewfinders that can “de-squeeze” the anamorphic image so that you can view it with the correct aspect ratio. The Glass Hub film was shot using a Sony PMW-F5 recording to the R5 raw recorder. The PMW-F5 has the ability to de-squeeze the image for the viewfinder built in. But I also used an Atomos Shogun Inferno to monitor as I was going to be producing HDR versions of the film. The Shogun Inferno has both 2x and 1.33x de-squeeze built in so I was able to take the distorted S-Log3 output from the camera and convert it to a HDR PQ image and de-squeeze it all at the same time in the Inferno. This made monitoring really easy and effective.
I used DaVinci Resolve for the post production. In the past I might have done my editing in Adobe Premiere and the grading in Resolve. But Resolve is now a very capable edit package, so I completed the project entirely in Resolve. I used the ACES colour managed workflow as ACES means I don’t need to worry about LUT’s and in addition ACES adds a really nice film like highlight roll off to the output. If you have never tried a colour managed workflow for log or raw material you really should!
The SLR Magic 65-1.33 paired with the Fujinon MK lenses provides a relatively low cost entry into the world of anamorphic shooting. You can shoot anywhere from around 30-35mm to 135mm. The PD Movie dual motor focus system means that there is no need to try to use both hands to focus both the anamorphot and the lens together. The anamorphot + lens behave much more like a quality dedicated anamorphic zoom lens, but at a fraction of the cost. While I wouldn’t use it to shoot everything the Anamorphot is a really useful tool for those times you want something different.
The main lenses I used for my recent Sony Venice shoot in Arizona were the Sigma Full Frame High Speed primes in PL mount.
These are really really nice lenses!
As they cover a full frame sensor such as the one in Sony’s Venice high end digital cinematography camera these are pretty future proof lenses. They are all fast lenses with most of them opening up to T1.5. At T1.5 you have a 20, 24, 35, 50 and 85mm lenses and at T2.0 you can go as wide as 14mm and as long as 135mm.
They are of all metal construction, the build quality is absolutely first class. As soon as you pick one up it just exudes quality. They are not light weight lenses, coming in at between 1kg and 1.3kg in PL mount form, but that weight gives you the confidence that these are lenses that will last. Lenses that will stand up to daily professional use on a film or documentary shoot. They are dust and moisture sealed, which is probably just as well as on this shoot there was a lot of blowing sand and dust. Our on set photographer was having problems with sand and grit in his lenses by the end of the shoot, but the Sigmas just shrugged it off.
The focus and aperture markings are very clear and easy to read they even glow in the dark! The focus ring rotates through a full 180 degrees and both the focus and aperture rings have standard 0.8 pitch teeth for follow focus controls etc. The gear rings are all the same distance from the mount so there is no need to move the follow focus when changing lenses.
The lenses are available with PL, E mount or EF mounts. The set I had were fitted with PL. The mounts are not user interchangeable, but you can have the mount swapped by Sigma if you do find that you need to change it for some reason.
I shot several scenes with the 20mm lens using the Venice’s full frame 6K x 4K mode. Examining these images in post production reveals that the 20mm is really sharp right out into the corners. I also shot with the lenses wide open in some pretty dark places and even wide open they stay tack sharp. Take a look at the image below, it’s really sharp. If you click on the image you can enlarge it to view it at close to the original 6K resolution.
Shooting night scenes with the 135mm wide open also gave beautiful results. When shooting with a shallow DoF all the lenses have a very pleasing bokeh. This is perhaps in part thanks to the use in all of the lenses of a 9 blade, rounded diaphragm aperture system.
When changing focus mid shot breathing is minimal and the focus ring is silky smooth. A really nice touch is the use of a damper at the focus stops so there is no noise if you hit the end stops.
During the shoot I used the 20,24,35,50,85 and 135mm lenses and they all performed really well. Looking at the footage in the grading suite it looks sharp and there are no nasty distortions. I did notice a touch of barrel distortion with the 24mm but this is to be expected with a wide lens on a full frame sensor. All the lenses matched really well, the colour remaining constant throughout the whole range. The look from the lenses was very neutral. Lens flare was extremely well controlled and I didn’t notice my blacks becoming washed out in high contrast situations. When shooting into the sun or at a direct light source any flare that I did see was normally quite pleasing.
The shot below was obtained shooting towards the sun when it was very low in the sky, yet the lens behaved flawlessly retaining deep blacks and a very high contrast image.
These lenses helped me capture some truly beautiful images with the Venice camera. I’ve long been a fan of Sigmas more recent lens designs. I have several of the Sigma Art Lenses and these have always performed exceptionally well. These prime lenses take things one step further putting world class optics into housings designed for manual control and the rigours of professional film and video productions. They are very competitively priced, especially when you consider that these are full frame lenses. I really hope to be able to use them again on future shoots. They really are top notch lenses and the images I captured with them look gorgeous.
This post follows on from my previous post about sensors and was inspired by one of the questions asked following that post.
While sensor size does have some effect on low light performance, the biggest single factor is really the lens. It isn’t really bigger sensor that has revolutionised low light performance. It’s actually the lenses that we can use that has chnge our ability to shoot in low light. When we used to use 1/2″ or 2/3″ 3 chip cameras for most high end video production the most common lenses were the wide range zoom lenses. These were typically f1.8 lenses, reasonably fast lenses.
But the sensors were really small, so the pixels on those sensors were also relatively small, so having a fast lens was important.
Now we have larger sensors, super 35mm sensors are now common place. These larger sensors often have larger pixels than the old 1/2″ or 2/3″ sensors, even though we are now cramming more pixels onto the sensors. Bigger pixels do help increase sensitivity, but really the biggest change has been the types of lenses we use.
Let me explain:
The laws of physics play a large part in all of this.
We start off with the light in our scene which passes through a lens.
If we take a zoom lens of a certain physical size, with a fixed size front element and as a result fixed light gathering ability, for example a typical 2/3″ ENG zoom. You have a certain amount of light coming in to the lens.
When the size of the image projected by the rear of the lens is small it will be relatively bright and as a result you get an effective large aperture.
Increase the size of the sensor and you have to increase the size of the projected image. So if we were to modify the rear elements of this same lens to create a larger projected image (increase the image circle) so that it covers a super 35mm sensor what light we have. is spread out “thinner” and as a result the projected image is dimmer. So the effective aperture of the same lens becomes smaller and because the image is larger the focus more critical and as a result the DoF narrower.
But if we keep the sensor resolution the same, a bigger sensor will have bigger pixels that can capture more light and this makes up for dimmer image coming from the lens.
So where a small sensor camera (1/2″, 2/3″) will typically have a f1.8 zoom lens when you scale up to a s35mm sensor by altering the projected image from the lens, the same lens becomes the equivalent of around f5.6. But because for like for like resolution the pixels size is much bigger, the large sensor will be 2 to 3 stops more sensitive, so the low light performance is almost exactly the same, the DoF remains the same and the field of view remains the same (the sensor is larger, so DoF decreases, but the aperture becomes smaller so DoF increases again back to where we started). Basically it’s all governed by how much light the lens can capture and pass through to the sensor.
It’s actually the use of prime lenses that are much more efficient at capturing light has revolutionised low light shooting as the simplicity of a prime compared to a zoom makes fast lenses for large sensors affordable. When we moved to sensors that are much closer to the size of sensors used on stills cameras the range and choice of affordable lenses we could use increased dramatically. We were no longer restricted to expensive zooms designed specifically for video cameras.
Going the other way. If you were to take one of todays fast primes like a common and normally quite affordable 50mm f1.4 and build an optical adapter of the “speedbooster” type so you could use it on a 2/3″ sensor you would end up with a lens the equivalent of a f0.5 10mm lens that would turn that 2/3″ camera into a great low light system with performance similar to that of a s35mm camera with a 50mm f1.4.
I’ve been shooting with the Fujinon MK18-55mm lens on my PXW-FS7 and PXW-FS5 since the lens was launched. I absolutely love this lens, but one thing has frustrated me: I really wanted to be able to use it on my PMW-F5 to take advantage of the 16 bit raw. Finally my dreams have come true as both Duclos and MTF have started making alternate rear mounts for both the MK18-55mm and the MK50-135mm.
So, when Fujinon contacted me and asked if I would be interested in shooting a short film with these lenses on my F5 I jumped at the chance. The only catch was that this was just over a week ago and the video was wanted for IBC which means it needed to be ready yesterday. And of course it goes without saying that it has to look good – no pressure then!
First challenge – come up with something to shoot. Something that would show off the key features of these beautiful lenses – image quality, weight, macro etc. I toyed with hiring a model and travelling to the Irish or Welsh coast and filming along the cliffs and mountains. But it’s the summer holidays so there was a risk of not being able to get an isolated location all to ourselves, plus you never know what the weather is going to do. In addition there was no story, no beginning, middle or end and I really wanted to tell some kind of story rather than just a montage of pretty pictures.
So my next thought was to shoot an artist creating something. I spent a weekend googling various types of artistry until I settled on a blacksmith. The video was going to be shown in both SDR and HDR and fire always looks good in HDR. So after dozens of emails and telephone calls I found an amazing looking metalwork gallery and blacksmith that was willing for a reasonable fee to have me and another cameraman take over their workshop for a day (BIG thank you to Adam and Lucy at Fire and Iron check out their amazing works of art).
Normally I’d carry out a recce of a location before a shoot to take photos and figure out what kind of lights I would need as well as any other specialist or unusual equipment. But this time there simply wasn’t time. We would be shooting the same week and it was already a very busy week for me.
The next step before any shoot for me is some degree of planning. I like to have a concept for the video, at the very least some outline of the shots I need to tell the story, perhaps not a full storyboard, but at least some kind of structure. Once you have figured out the shots that you want to get you can then start to think about what kind of equipment you need to get those shots. In this case, as we would be shooting static works of art I felt that having ways to move the camera would really enhance the video. I have a small Jib as well as some track and a basic dolly that is substantial enough to take the weight of a fully configured PMW-F5 so these would be used for the shoot (I’m also now looking for a slider suitable for the F5/F55 that won’t break the bank, so let me know if you have any recommendations).
So the first items on my kit list after the camera and lenses (the lenses were fitted with Duclos FZ rear mounts) was the jib and dolly. To achieve a nice shallow depth of field I planned to shoot as close to the lenses largest aperture of T2.9 as possible. This presents 2 challenges. The F5’s internal ND filters go in 3 stop steps – that’s a big step and I don’t want to end up at T5.6 when really I want T2.9, so 1 stop and 2 stop ND filters and my gucchi wood finished Vocas matte box would be needed (the wood look does nothing to help the image quality, but it looks cool). Oh for the FS7 II’s variable ND filter in my F5!
The second problem of shooting everything at T2.9 with a super 35mm sensor is that focus would be critical and I was planning on swinging the camera on a jib. So I splashed out on a new remote follow focus from PDMovie as they are currently on offer in the UK. This is something I’ve been meaning to get for a while. As well as the remote follow focus I added my Alphatron ProPull follow focus to the kit list. The Fujinon MK lenses have integrated 0.8 pitch gears so using a follow focus is easy. I now wish that I had actually purchased the more expensive PDMovie follow focus kit that has 2 motors as this would allow me to electronically zoom the lens as well as focus it. Oh well, another thing to add to my wish list for the future.
One other nice feature of the Fujinon MK’s is that because they are parfocal you can zoom in to focus and then zoom out for the wider shot and be 100% sure that there is no focus shift and that the image will be tack sharp. Something you can’t do with DSLR lenses.
Lighting: This was a daylight shoot. Now I have to say that I am still a big fan of old school tungsten lighting. You don’t get any odd color casts, it gives great skin tones, it’s cheap and the variety and types of lamp available is vast. But as we all know it needs a lot of power and gets hot. Plus if you want to mix tungsten with daylight you have to use correction gels which makes the lights even less efficient. So for this shoot I packed my Light and Motion Stella lamps.
The Stellas are daylight balanced LED lamps with nice wide 120 degree beams. You can then use various modifiers to change this. I find the 25 degree fresnel and the Stella 5000 a particularly useful combination. This is the equivalent to a 650W tungsten lamp but without the heat. The fresnel lens really helps when lighting via a diffuser or bounce as it controls the spill levels making it easier to control the overall contrast in the shot. The Stella lights have built in batteries or can be run from the mains. They are also waterproof, so even if it rained I would be able to have lights outside the workshop shining in through the windows if needed.
I always carry a number of pop-up diffusers and reflectors of various sizes along with stands and arms specifically designed to hold them. These are cheap but incredibly useful. I find I end up using at least one of these on almost every shoot that I do. As well as a couple of black flags I also carry black drapes to place on the floor or hang from stands to reduce reflections and in effect absorb unwanted light.
To check my images on set I use an Atomos Shogun Flame. Rather than mounting it on the camera, for this shoot I decided to pack an extra heavy duty lighting stand to support the Shogun. This would allow my assistant to use the flame to check focus while I was swinging the jib. The HDR screen on the Shogun allows me to see a close approximation of how my footage will look after grading. It also has peaking and a zoom function to help with focussing which was going to be essential when the camera was up high on the jib and being focussed remotely. I also included a TV-Logic LUM171G which is a 17″ grading quality monitor with 4K inputs. The larger screen is useful for focus and it’s colour accuracy helpful for checking exposure etc.
For audio I packed my trusty UWP-D wireless mic kit and a pair of headphones. I also had a shotgun mic and XLR cable to record some atmos.
As well as all the larger items of kit there’s also all the small bits and bobs that help a shoot go smoothly. A couple of rolls of gaffer tape, crocodile clips, sharpies, spare batteries, extension cables etc. One thing I’ve found very useful is an equipment cart. I have a modiffied rock-n-roller cart with carpet covered shelves. Not only does this help move all the kit around but it also acts as a desk on location. This is really handy when swapping lenses or prepping the camera. It can save quite a bit of time when you have a mobile work area and somewhere you can put lenses and other frequently used bits of kit.
The day before the shoot I set everything up and tested everything. I checked the backfocus adjustment of the lenses. Checked the camera was working as expected and that I had the LUT’s I wanted loaded into both the camera and the Gratical viewfinder. With the camera on the jib I made sure I had the right weights and that everything was smooth. I also checked that my light meter was still calibrated against the camera and that the lens apertures matched what I was expecting (which they did perfectly). Color temperature and colorimetry was checked on the TVLogic monitor.
It’s worth periodically checking these things as there would be nothing worse than rocking up for the shoot only to find the camera wasn’t performing as expected. If you rent a cinema camera package from a major rental house it would be normal to set the camera up on a test bench to check it over before taking it away. But it’s easy to get lazy if it’s your own kit and just assume it’s all OK. A full test like this before an important shoot is well worth doing and it gives you a chance to set everything up exactly as it will be on the shoot saving time and stress at the beginning of the shoot day.
On the morning of the shoot I loaded up the car. I drive a people carrier (minivan to my friends in the USA). Once you start including things like a jib, track and dolly, equipment cart, 6x tungsten lights, 4 x LED lights, plus camera, tripods (including a very heavy duty one for the jib) the car soon fills up. A conventional saloon would not be big enough! One word of caution. I was involved in a car crash many years ago when the car rolled over. I had camera kit in the back of the car and the heavy flight cases did a lot of damage crashing around inside the car. If you do carry heavy kit in the car make sure it’s loaded low down below the tops of the seats. You don’t want everything flying forwards and hitting you on the back of your head in a crash. Perhaps consider a robust steel grill to put between the cargo compartment and the passenger compartment.
On arrival at the location, while it’s very tempting to immediately start unloading and setting up, I like to take a bit of a break and have a tea or coffee first. I use this time to chat with the client or the rest of the crew to make sure everyone knows what’s planned for the day. Taking a few minutes to do this can save a lot of time later and it helps everyone to relax a little before what could be a busy and stressful day.
Now it’s time to unpack and setup. I find it’s better to unpack all the gear at this time rather than stopping and starting throughout the day to unpack new bits of kit. Going to the car, unlocking, unpacking, locking, back to the set etc wastes time. This is where the equipment cart can be a big help as you can load up the cart with all those bits and pieces you “might” need… and inevitably do need.
The blacksmiths workshop was a dark space about 6m x 5m with black walls, open on one side to the outside world. Blacksmiths forges (so I learnt) are dark so that the blacksmith can see the glow of the metal as it heats up to gauge it’s temperature. On the one hand this was great – huge amounts of relatively soft light coming from one direction. On the other hand the dark side was very dark which would really push the camera and lenses due to the extreme contrast this would create.
We set the jib up inside the workshop to shoot the various processes used by a blacksmith when working with iron and steel. Apparently there are only 7 different processes and anything a blacksmith does will use just these 7 processes or variations of them.
Most of the shots done on the jib would be shot using the Fujinon MK18-55mm, so that’s the lens we started with. For protection from flying sparks a clear glass filter was fitted to the lens. While the finished film would be a 24p film, most of the filming was 4K DCI at 60fps recording to 16 bit raw. This would give me the option to slow down footage to 24p in post if I wanted a bit of slow motion.
When we did need to do a lens swap it was really easy. The Vocas matte box I have is a swing-away matte box. So by releasing a lever on the bottom of the matte box it swings out of the way of the lens without having to remove it from the rods. Then I can remove the lens and swap it to the other lens. The MK50-135mm is the same size as the MK18-55mm. The pitch gears are also in the same place. So swapping lenses is super fast as the follow focus or any focus motors don’t need to be re-positioned and the matte box just swings back to exactly the same position on the lens. It’s things like this that really separate pro cinema lenses from DSLR and photography lenses.
For exposure I used the cameras built in LUT’s and the 709(800) LUT. I set the camera to 800EI. I used a grey card to establish a base exposure, exposing the grey card at 43% (measuring the 709 level). I used a Zacuto Gratical viewfinder which has a great built in waveform display, much better than the one in the camera. I also double checked my light levels with a light meter. I don’t feel that it’s essential to use a light meter but it’s a useful safety net. The light meter is also handy for measuring contrast ratios across faces etc but again if you have a decent waveform display you don’t have to have a light meter.
For the next 3 hours we shot the various processes seen in the video. Trying to get a variety of different shot. But when each process is quite similar, usually involving the anvil and a large hammer it was difficult to come up with shots that looked different.
In the afternoon we set up to shoot the interview sequence. The reason for doing this was to not only provide the narrative for the film but also to help show how the lenses reproduce skin tones. The Fujinon MK series lenses are what I would describe as “well rounded”. That is, not too sharp but not soft either. They produce beautifully crisp pictures without the pictures looking artificially sharp and this really helps when shooting people and faces. They just look really nice.
For the interview shot I used one of the Stella 5000 lights with the 25 degree fresnel lens aimed through a 1m wide diffuser to add a little extra light to supplement the daylight. This allowed me to get some nice contrast across the blacksmiths face and nice “catch light” highlights in his eyes. In addition the little bit of extra light on his face meant that the back wall of the forge would appear just that bit darker due to the increased contrast between his face and the back wall. This is why we light…. not just to ensure enough light to shoot with, I had plenty of light, if I remember right I had a 1 stop ND in the matte box. But to create contrast, it’s the contrast that gives the image depth, it’s contrast that makes an image look interesting.
The final stage was to shoot the treasure chest and ornate jars that would show off the the lenses macro and close up performance. The treasure chest is a truly amazing thing. It weighs around 80kg. The locking mechanism is quite fascinating and I still struggle to believe that it was all hand made. The small metal jars are made out of folded and welded steel. It’s the folds in the metal that create the patterns that you see.
Once again we used the jib to add motion to the shots. I also used the macro function of both the MK18-55mm and MK50-135mm lenses. This function allows you to get within inches of the object that you are shooting. It’s a great feature to have and it really adds to the versatility of these lenses.
We wrapped at 7pm. Time to pack away the kit. It’s really important not to rush at this stage. Like everyone else I want to get home as quick as I can. But it’s important to pack your kit carefully and properly. There is nothing more annoying than when you start prepping for the next shoot finding that something has been broken or is missing because you rushed to pack up at the end of the previous shoot. Once you have packed everything away don’t forget to do that last walk through all the locations you’ve shot in to make sure you haven’t forgotten something.
I shot a little over hour of material. As it was mostly 60p 4K raw that came to about 1.5TB This was backed up on site using a Nexto-DI NSB25 which is a stand alone device that makes 2 verified copies of everything on 2 different hard drives. The film was edited using Adobe Premiere CC which handles Sony’s raw very easily. Grading was completed using DaVinci Resolve. I spent 2 days editing and a day grading the first version of the film. Then I spent another day re-grading it for HDR and producing the different versions that would be needed. All in, including coming up with the concept, finding the location, prepping, shooting and post took it took about 7 to 8 full work days to put this simple 4 minute film together.
Having done a fair bit of shooting with the new and very nice Fujinon MK 18-55mm E-Mount lens I decided to take a much closer look at the Fujinon Cabrio XK6x20 20 to 120mm T3.5 lens with the servo hand grip.
The price of this lens is very competitive and it can now be found as low as £11K/$16K. Lets not try to pretend that good quality PL mount zooms are cheap, but this is a great price for what is very high quality glass. The 20 to 120mm zoom range is nice and of course it’s truly parfocal there is a back focus adjuster along with macro function.
Like the other similar ENG style PL zooms this lens is quite heavy. The front element of the lens is huge and I’m sure a lot of the weight comes from this big lump of glass. One of the nice things about this lenses baby brother the MK 18-55, is that the 18-55 is really very light, which is great on the smaller cameras like the FS5 or FS7.
The 20-120mm Cabrio exudes quality. The build quality of the lens is wonderful, the witness marks are crisp and well engraved, the servo zoom is silky smooth. The large servo module acts as a handgrip just like traditional ENG lenses and it really comfortable to hold and use this way. But if you don’t need it it can be easily removed leaving the bare bones lens body and saving a little bit of weight. There are the usual 0.8 mod pitch gears on each of the focus zoom and iris rings. Focus ring travel is huge at about 200 degrees and due to the physical size of the lens this is as much as I’d ever want. Even towards infinity there is still a nice range of travel so focussing accurately on distant objects is easy.
But what about the image quality, how does the lens perform in real world situations?
To find out I used it for a shoot in Norway. The shoot was for TV manufacturer Philips. We wanted to obtain some high quality 4K HDR footage to show off the capabilities of a new 4K OLED Ambilight TV. Unfortunately the weather conditions on the shoot were pretty grim most of the time and this made it all the more challenging. But I’m pleased to say that both lenses performed very well despite snow, ice and cold.
One of the great things about having both the high end Cabrio 20-120mm and the budget friendly 18-55mm for the shoot was that the overall look of the images from the FS5 and F5 was the same. Often mixing lenses from different manufacturers results in different looking images giving the colourist more work to do in post. Fujinon now have a range of lenses to suit most budgets from the high end Cabrio 19-90mm T2.9 down through the Cabrio 20-120 T3.5 to the MK 18-55 T2.9.
So what do the images from these lenses look like? I’m afraid I can’t show any of the footage from the Philips shoot yet, I should be able to show it later in the year. Below are a couple of frame grabs to give you an idea of the kind of images you can get. We didn’t shoot the same shots with the F5/XK6x20 and FS5/MK18-55 at the same time, I was the only cinematographer. So I don’t have a side by side comparison from the shoot, but the different scenes shot with each lens/camera combo match really well.
TESTING BOTH LENSES:
In order to better directly compare the two lenses I shot some test shots. The XK6x20 on my F5 and the MK18-55 on my FS7. Both cameras were set to the same settings and hypergamma 3 with the cinema matrix used. The images you will see below have not been touched, this is how they looked straight from the camera. If you click on the picture you should get a link to the full frame 4K image, but do remember this are Jpegs.
I tried to get the same shots with both combinations but you will see some small variations. I apologise for that. To give as fair a comparison as possible I did most of the shots at 20mm and 55mm, but then in addition shot at 18mm on the MK18-55 and 120mm on the XK6X20 so you can see the additional range each lens offers.
First test was of a neighbours Cherry tree in blossom.
The next test was a simple setup shot of a couple of beer bottles on a table with strong sunlight from above and behind to create deep contrast. I wanted to see if either lens showed signs of loosing shadow detail due to the very large, very bright table top introducing flare into the shadows.
My conclusion with the above shots is that there is remarkably little difference between these two lenses. Both perform extremely well. I think the XK6X20 might be marginally sharper at the wide end than the 18-55mm, either that or the slightly better viewfinder of the F5 is allowing me to focus more precisely. In addition I think the bokeh of the more expensive Cabrio is marginally smoother than the 18-55, but again it’s a tiny difference (not as big as the difference in white balance of the two cameras).
Finally a shot of my ugly mug just so you can take a look at some skin tones.
Again very little difference between these lenses which is a good thing. Both perform very well, both produce pleasing images. Sure the XK6X20 20-120mm is more than twice the price of the MK18-55 but then it does offer twice the zoom range and it’s very hard to make fast parfocal lenses with big zoom ranges for large sensors. There will be a companion MK50-135mm lens coming later in the year, so with both the MK lenses you will be able to get the full range of the XK6X20 and a bit more, provided you don’t mind swapping lenses. It’s a tough choice if you have an E-mount Sony camera, which to get? For E-Mount I think the pair of MK lenses will be the way to go. If you have a PL mount camera the XK6X20 has to be a very serious contender. It’s a great all-round cinema zoom lens and a realistic price. Whichever way you do go you won’t be disappointed, these are proper cinema lenses.
I have just return from one of the most challenging shoots I have been involved in. The shoot took place over 5 days in and around Tromso in Norway. The aim was to gather footage to show off the capabilities of a new type of 4K TV from Phillips.
We shot the Northern Lights, we shot dog sledding , snow mobiles, shots of the city and sailing on the fjords. Each part of the shoot had many challenges and a lot of the shoot took place at night and at night the crew slept in cabins, tents and on the yachts. Shooting from the ice and snow covered deck of a yacht in temperatures well below zero is not something I enjoyed. And to top it all off the weather was pretty grim fro most of the shoot. Heavy snow showers, freezing temperatures and towards the end strong winds.
Because image quality is paramount for this project I choses to use the best lenses I could, but at the same time space and time constraints dictated that zoom lenses would be desirable. We were shooting 16 bit raw as well as XAVC class 480 on my PMW-F5 and some pick-up shots in UHD XAVC-L on a PXW-FS5. For the PMW-F5 the primary lens was the Fujinon Cabrio XK6x20, 20-120mm PL zoom and to ensure we had similar looking images from the FS5 I used the new Fujinon XF 18-55mm. I have to say that I’m quite in love with both of these lenses.
The Cabrio 20-120 is a beautiful lens and it’s really nice to have a servo zoom that is truly parfocal. The 20-120 produces really nice images even in the most challenging of conditions and at T3.5 it’s reasonably fast throughout the entire zoom range. This was the lens that I used for the majority of the shoot, in particular for the many night scenes we shot. The E-Mount 18-55 on the FS5 produces images that matched really well with the bigger lens and camera. This is a combination I would love to use on more shoots where the budget will allow.
One particular scene that we had to shoot was particularly challenging. It was a set up shot of a night time arrival of a couple of snowmobiles at a Sami camp site. The Sami people are the indigenous people of Northern Norway and they have a particular style of tent know as a Laavu which is similar to a teepee or wigwam. The idea behind the shot was to have the snow scooters arriving with headlights blazing and for the drivers to then enter the tent lit only by the light of a campfire inside the tent. At the time of the shoot it was snowing heavily and was totally dark. Turn off the lights of the snowmobiles and you could not see a thing.
While modern cameras like the F5 are very sensitive, the light of a campfire inside a tent will not adequately light a scene like this on it’s own. I didn’t want a totally dark background, so I decided that I would subtly light the trees of the forest that we were in to add some drama and give some depth to the background and a sense of being in a forest.
As we were travelling continuously on this shoot there was no space for a large or complex lighting kit and the remote location meant we needed battery powered lights. In addition I knew before we left that there was a chance of bad weather so I needed lights that would work whatever mother nature decided to throw at us.
I decided to take a set of 3 Light & Motion Stella battery powered LED lights. It’s just as well I had the Stella lamps as on top of all the other difficulties of the shoot the weather decided it was not going to play ball. We had to shoot the scene (and much of the shoot) in the middle of a snow storm. Fortunately the Stella lights are completely waterproof, so I didn’t need to worry about rain or snow protection. Just set them up turn them on and use the built in dimmer to set the light output.
To light the scene I set up a Stella Pro 5000 in the woods behind the Sami tent, aimed through the trees and pointed directly towards the camera. I chose to backlight the trees to provide a sense of there being trees rather than lighting them. I felt this would look less lit than throwing a ton of light into the forest from the front and I’m pleased with the result.
The Stella Pro 5000 is very bright for a compact battery operated light, it’s 5000 lumen 120 degree output that is pretty close to what you would get from a 200W HMI, it’s very bright. It has a very high CRI and gives out great quality daylight balanced light. It was positioned so that the light itself was behind the tent on a small bank, about 20m back in the woods. You couldn’t see it in the shot, but the light coming through the trees created shafts of light in the snow and the trees appeared as silhouettes. It added depth and interest to what would have otherwise been a near totally black background.
Then to provide a small amount of light so that we could see the riders of the snow scooters as they walked to the tent I used a Stella 2000. I didn’t really want the light from this lamp to be too obvious as this would really make the scene look “lit”. I didn’t need the full 2000 lumen output so I used the built in dimmer to reduce the output to around 70%.
The third light was a small Stella 1000 and this was placed inside the tent with a scrunched up orange gel. The Stella 1000 would typically be used as a camera top light, but it’s full dimmable and produces a very high light quality, making it suitable for many applications. The creases and folds in the orange gel helped break up the light a little creating a less lit look sympathetic to the fire inside the tent.
It allowed me to increase the illumination in the tent, adding to the light from the fire without it being obvious that the tent interior was lit. For some of the shots I had an assistant sit in the tent, out of shot and slowly move the gel in front of the light to add a little movement to the light to mimic the firelight even better.
At the moment I can’t show you the footage. That will have to wait until after the launch of the TV. But I’m really pleased with the way this scene came out. It’s challenging trying to shoot in the dark, in a blizzard, in temperatures well below freezing. Every aspect of getting this scene was hard. Opening a flight case to get out some kit meant getting snow on everything inside it. Just positioning the light up the woods was tough, the snow was up above my knees as I waded through it. Operating the camera is so much harder when it has a rain cover on it. The viewfinder was constantly misting up as snow fell on it non stop. Seeing the witness marks on the lens is difficult (although thankfully the marks on the Fujinon 20-120 are huge and easy to see).
But sometimes it’s challenges like these that make the job interesting. I know I was cursing and swearing at times trying to make these shots work, but seeing the scene come to life in the grade is all the more rewarding.
I’ll be writing more about the Fujinon 20-120 very soon, so why not subscribe to my blog using the subscribe bottom on the left.
