Prepping my camera today for a shoot tomorrow. I’ll be shooting with the Fujinon MK18-55mm and MK50-135mm lenses fitted with Duclos FZ mount adapters. I’ve been using the MK18-55mm on my FS7 and FS5 for some time and I have to say I really love this lens. It produces beautiful images with silky smooth bokeh, it’s parfocal and it covers a very hand range of focal lengths. I’ve been wanting to use this lens on my F5 for some time and now at last I can. These lenses work great on the F5 and F55. They are very light compared to most PL lenses and this really helps with the cameras balance, especially if shooting handheld. They are also very cost effective.
The light lens weight means I need less weight on my jib than I would have with most similar PL zoom lenses. Also being nice and fast at T2.9 I know I can get great shallow DoF. Tomorrow I’m going to be shooting 2 amazing artists that create incredibly detailed things out of large lumps of iron and steel. I’ll be shooting examples of some of the finest works of metallic art along with all the key parts of the process of creating them. There will be beauty, iron, steel, heat, flames and sparks. I’ll try to post pictures from the shoot over the weekend and once the video is done it will be online for all to enjoy.
In addition to the recent announcement from Duclos, MTF services in the UK have just announced that they will be introducing a conversion service for the popular new Fujinon MK zoom lenses. Currently these lenses are E-Mount only, but MTF will be producing kits to convert the lens mounts so that they can be used with cameras that use the micro 4/3rds mount as well as the Sony FZ mount. This is great news for owners of Sony’s F5 and F55 cameras.
Here’s the text of their press release:
Since the launch of Fujinon’s MK lenses in February this year, users have continued to request a greater range of mounts beyond the native E-Mount that can be found on the 18-55mm and 50-135mm lenses. MTF have now addressed these requests and have designed brand new solutions to convert the lenses to Micro four thirds and FZ mount systems
Mike Tapa, Managing Director at MTF Services said: “Since these excellent lenses from Fujinon were launched earlier this year, we’ve had more and more of our customers asking for us to produce a solution to open up the use of the MK lenses for use across a broader range of camera bodies. We’re now pleased to announce that we have designed brand-new adapter mounts for both micro four thirds and FZ systems to work seamlessly with both the 18-55mm and 50-135mm lenses.
Fitting the new mount options for the Fujinon MK lenses will be offered as a service from the team at MTF Services. Simply ship your lens over to MTF’s London-based workshop, and the team will fit your preferred mount before shipping back to you, fully tested, professionally adapted, cleaned and ready for use before being safely couriered back to your door.
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.
Fujinon have a long history of producing excellent lenses. When I used to shoot motorsports, windsurfing and TV news I used to use Fujinon lenses on my 2/3″ Betacam, Digibeta and DVCAM camcorders. I still have a Fujinon remote zoom demand sitting in the cupboard. Today Fujinon still produce high quality lenses for broadcast cameras.
But Fujinon don’t just make lenses for broadcast cameras, they also make PL mount lenses for use with super 35mm cameras. Perhaps their best known cinema lenses are their “Cabrio” zoom lenses. When it was introduced the 19-90mm T2.9mm Cabrio was ground breaking as it offered a silky smooth zoom servo with an ENG style handgrip on a compact zoom lens.
The 19-90 Cabrio was the workhorse servo zoom that many F5/F55, Red and Arri users had been wanting for a long time. I’ve used the Cabrio’s and they are great lenses, I’d love to own one, but my budget just won’t stretch that far. The 19-90 costs around $40K but it is a beautiful lens.
Aware of the demand for a similar lens at a lower cost, last year Fujinon introduced a more affordable 20-120mm T3.5 lens. However even though much cheaper, at £13.5K/$16K it is still quite an expensive lens, especially when you consider that a camera like the Sony FS7 only costs £6k/$8K.
That brings us to today. Fujinon have developed a pair of new lenses specifically for E-Mount cameras. An 18-55 and a 55-135. The 55-135 isn’t ready just yet but the wider one, the MK18-55 is, and I’ve been lucky enough to have been loaned one to test.
As you can see the lens looks very similar to the more expensive XK20-120, but it’s actually a bit smaller and a lot lighter. The lens is an 18-55mm T2.9 (f2.8) Parfocal zoom. Parfocal means that the focus does not shift as you zoom as happens with most DSLR lenses. It’s E-Mount only, so you can’t use it on a Canon camera, but you can put it straight on to a FS5, FS7, even an A7S/A7R (The lens is designed for s35/APS-C so you need to use crop sensor mode or clear image zoom on a full frame sensor). No adapters needed! It’s a manual lens, no autofocus and there isn’t a zoom servo. But what you do get is beautiful image quality!
The short back focus distance of E-Mount compared to PL or EF makes it easier to produce an affordable high quality zoom lens, that’s why this lens is E-Mount only. To ensure that the lens remains parfocal on different cameras it has a backfocus adjustment ring. This ring also functions as a macro focus ring by pressing a small button. This allows you to focus on objects around 1ft/38cm from the lens. When not using macro the minimum focus distance is 0.85m/2ft9″.
The iris is a 9 blade iris with curved blades that produces a pleasing bokeh both inside and outside of focus.
To keep the weight down a lot of the lens exterior is made from plastic. It is quite a long (in length) lens. If it was all metal it would make a light camera like the FS7 front heavy, so while perhaps it doesn’t have the tactile feel of a $40K Cabrio it also doesn’t have the weight, the 19-90 is almost 6lb/2.7kg, the MK18-80 is just 34.6ox/980g. However it does feel well made. The focus, zoom and iris rings all feel very smooth and have just the right amount of rotation resistance and damping.
The focus ring has around 180 degrees of travel and the focus markings (in both metric and imperial) are clear and easy to read. Each ring also has a 0.8mm pitch gear ring.
In use I found the lens a pleasure to use. I can perform nice smooth manual zooms with ease. It is easy to focus with just the right amount of focus travel, not too much not too little. Focus breathing is very well controlled and quite minimal. It’s certainly one of the best lenses I’ve used at this price point. It feels and behaves like a proper cinema lens.
So what about the image quality? This lens does not disappoint. The images are sharp from edge to edge, corner to corner throughout the zoom range, even when wide open at T2.9. Contrast is good and even when shooting into the sun, flare is minimal. A square lens hood is provided with the lens that works well, but of course you can also use it with a matte box if you wish.
To me the images from this lens look closer to the ones I get from prime lenses than a zoom. I can see this lens being used instead of a set of primes for many productions and it certainly works out very cost effective compared to a set of decent prime lenses.
Chromatic aberration is well controlled and minimal and I didn’t notice any significant colour cast or tint. The lens is also remarkably free from geometric distortions (unlike the Sony 18-105 that is supplied as a kit lens with the FS5 that’s full of all kinds of distortions). There is a little, but it’s no worse than most other wide zoom lenses and nothing that I am concerned about.
While T2.9 isn’t super fast it is at least a stop faster than most (all?) of the other budget cinema zooms on the market. Plus it’s absolutely useable at T2.9 unlike some other lenses that go a little soft or become prone to flare when wide open. I’d be perfectly happy to shoot at T2.9 all day.
So, in case you haven’t noticed yet I really like this lens. It may not have the zoom range of the new Sony 18-110, but it’s a stop faster. It may not have the ability to be used on different mounts like the Canon 18-80 t4.4 but again it’s faster and has a real manual focus ring with hard stops and repeatable calibration. The new Zeiss 21-100 t2.9/t3.9 is interesting, but more expensive and not as wide nor as fast. You should be able to buy both the 18-55 and the 50-135 for less than the Zeiss.
So, if you are in the market for a proper digital cinema lens for your FS5 or FS7 do take a close look at the Fujinon MK18-55. I hope to get a chance to shoot some more interesting footage with this lens very soon and share it with you.
UPDATE: I should have anticipated this, I’ve been asked this many times today already. Given that the new Sony 18-110 f4 and the MK18-55mm are similar prices, which one would I choose?
I would probably choose the Fujinon, but my needs are not necessarily the same as others. Very often if I need a zoom lens I need a very big zoom range. For my storm chasing I use a Tamron 16-300mm dslr lens, I need a BIG zoom range. It’s a compromise, I know I can get better image quality with primes or a shorter zoom, but I often need to go from super wide to super long and the Tamron 19x 16-300mm zoom fits the bill. For run and gun handheld work I actually quite like the cheaper Sony 18-105mm. Sure the focus is a bit wonky and it has a lot of different geometric distortions, but it’s really small, very light and the autofocus works OK. It does the job I need of it.
Currently I own various prime lenses. I also have the Sigma 18-35mm f1.8 which I rate highly. For a drama or documentary shoot with my FS7 right now I would probably pack my 18-35mm Sigma, 20mm Sigma, my 14, 35, 55 and 85mm Samyangs plus the 16-300mm Tamron. I could see the Fujinon 18-55mm replacing ALL of the lenses below the 85mm Samyang, except perhaps the 14mm. So instead of carrying 4 lenses, I only need to take one and achieve the same kind of image quality (the Samyangs are T1.4, but normally I stop them down to T2 -T2.8 as they are a bit soft wide open). I will have less breathing, plus I can zoom during the shot. In addition I’m getting near prime lens quality without the need to keep swapping lenses when I need a different focal length.
The Fujinon is light and compact a big bonus when travelling. Once the MK50-135mm becomes available the pair would cover the majority of drama or short film focal lengths. Just 2 light and compact lenses. For me the Sony at f4 just isn’t quite fast enough for film style productions – great for run and gun and general purpose shoots but it’s not really the lens I want.
The only question that remains is what should I get for my F5 with it’s PL/FZ mount? If only the MK18-55mm would fit the F5. Have to save my pennies for the Fujinon XK6x20 20-120mm.
When Sony launched the FS7 II they also launched a new lens to go along with it. The previous zoom lens that was bundled with the FS7 was the SELP28135G, a 28-135mm f4 zoom lens that would work with Super 35mm, APS-C and full frame cameras. While generally well received this lens is not without it’s problems. For a start it’s not really wide enough for use as a general purpose lens on an APS-C or Super 35mm sensor. The other problem is that the zoom is very slow. Even when set to manual zooming in and out takes a long time. You turn the zoom ring and then have to wait for the lens to catch up.
The new lens is a wider 18mm to 110mm f4 lens. This is a really useful zoom range for a Super 35mm camera. But the new lens can only be used on S35mm and APS-C cameras. It can’t be used with full frame cameras like the A7s in full frame mode.
But what about the zoom speed? Well this has been addressed too. On the 28-135mm lens the zoom function is electronic. There is no mechanical connection between the zoom ring and the optics of the lens. The 18-110 has a proper mechanical connection between the zoom ring and the internal lenses, so now you can crash zoom in and out as fast as you want. In addition the zoom servo motor is much faster and motorised zooms take place much more rapidly. One downside to this is that it’s a bit harder to control the zoom speed. You can do slow creeping zooms if you are very careful with the cameras zoom rocker, but it’s hard to do. The difference in pressure on the zoom rocker between creeping zoom and medium speed is tiny. The lens tended to change zoom speed quite quickly. While it is indeed very nice to have a variable speed motorised zoom, don’t expect the fine degree of control that you get from admittedly more expensive traditional ENG lenses. Lets face it this lens is only around £3K/$5K which is remarkable cheap for a parfocal s35mm zoom. Take a look at the video below for an idea of the zoom speeds etc.
Is it really parfocal? Well yes, it does seem to be parfocal. I only had the lens for a morning to play with, but in all my tests the focus remained constant throughout the zoom range.
So, what about focus? Like the 28-135mm lens there is a nice big focus ring that slides fore and aft.
In the rear position the focus is manual and there are calibrated focus markings and end stops. You get about 180 degrees of focus travel from 0.95m (3.1ft) to infinity (in autofocus you can focus slightly closer when the lens is at the wide end). The focus ring has 0.8mm pitch teeth for use with most standard follow focus units, although this gear ring is very close to the end of the lens, so it may be tricky to use if you have a matte box in place. Breathing is very well controlled and barely noticeable unless going through very large focus throws. Out of focus Bokeh isn’t bad either, I didn’t observe any nasty surprises in the limited time I had to play with the lens.
Sharpness and flare. The lens appears to be nice and sharp at the wide end but just a touch soft at the long end. It’s not bad overall but when shooting at 4K I could just about detect the lens becoming marginally softer as I zoomed in. The sample I had was a well used pre-production prototype, but I’m going to guess that the production lenses won’t be hugely different. Shooting the roof of a house against a bright sky revealed only a small amount of flare, certainly nothing out of the unusual for a zoom lens.
Overall I really like this lens. It even has a support point at the front of the lens body for additional stability. While f4 isn’t the largest of apertures it is quite usable and even wide open the lens performs well. For the money it is a lot of lens. I think we need to be realistic with our expectations for zoom lenses and large sensors. Bigger zoom ratios require bigger lens elements if we want to maintain a constant aperture. Bigger lens elements cost more to produce.
One advantage Sony have over the competition is that it’s easier to make zoom lenses for the very short flange back distance of the E-Mount cameras compared to the deeper flange back of PL or Canon mounts. The closest competition to this lens is the Canon 18-80mm T4.4 (f4 ish) which is a fair bit more expensive (£4K/$6K). If you want a similar zoom range then you’re looking at the beautiful Fujinon 20-120 T3.4 at around £14K/$19K.
I produced 3 video blogs during my trip to Norway to shoot the northern lights. These blogs are now on youtube for you to watch. In the first video I take a look at some of the equipment that I took to Norway for the trip. I also look at how I like to lay everything out before I pack it and give some insight into some of the accessories that I like to take.
The second video looks back at the first week of the trip. You will see examples of the weather we had to deal with as well as some information on how some of the time lapse sequences of the aurora were shot.
The third video is about shooting a sunrise with 3 different cameras. The Sony a6300, FDR-AX3000 Action Cam and the PXW-FS5.
Packing for the shoot.
At the bottom of the page you’ll find a quick cut of a small selection of some of the Aurora footage shot on this trip.
Lets face it cameras are becoming more and more sensitive. We no longer need the kinds of light levels that we once used to need. So why is lighting still so incredibly important. Why do we light?
Starting at a most basic level, there are two reason for lighting a scene. The first and perhaps most obvious is to add enough light for the camera to be able to “see” the scene, to get an adequate exposure. The other reason we need to light, the creative reason why we need to light is to create shadows.
It is not the light in a scene that makes it look interesting, it is the shadows. It is the contrast between light and dark that makes an image intriguing to our eyes and brain. Shadows add depth, they can be used to add a sense of mystery or draw the viewers gaze to the brighter parts of the scene. Without shadows, without contrast most scenes will be visually uninteresting.
Take a typical daytime TV show. Perhaps a game show. Look at how it has been lit. In almost every case it will have been lit to provide a uniform and even light level across the entire set. It will be bright so that the cameras can use a reasonable aperture for a deep depth of field. This helps the camera operators keep everything focus. The flat, uniform light means that the stars or contestants can go anywhere in the set and still look OK. This is lighting for exposure, where the prime driver is a well exposed image. The majority of the light will be coming from the camera side of the set or from above the set with all the light flooding inwards into the set.
Then look at a well made movie. The lighting will be very different. Often the main source of light will be coming from the side or possibly even the rear of the scene. This creates dark shadows on the opposite side of the set/scene. It will cast deep shadows across faces and it’s often the shadow side of a face that is more interesting than the bright side.
A lot of movie lighting is done from diagonally opposite the cameras to create very deep shadows on faces and to keep the background of the shot dark. If, as is typical in TV production your lights are placed where the cameras are and pointed into the set, then all the light will go into set and illuminate the set from front to back. If your lights are towards the side or rear of the set and are facing towards the cameras the light will be falling out of and away from the set rather than into the set. This means you can then keep the rear of the set dark much more easily. Having the main light source opposite the camera is also why you see far more lens flare effects in movies compared to TV as the light is often shining into the camera lens.
If you are shooting a night scene and you want to get nice clean pictures from your camera then contrast becomes key. When we think of what things look like at night we automatically think “dark”. But cameras don’t like darkness, they like light, even the modern super sensitive cameras still work better when there is a a decent amount of light. So one of the keys to a great looking night scene is to light the foreground faces of your cast well but keep the background very dark. You expose the camera for the bright foreground (which means you should not have any noise problems) and then rely on the fact that the background is dark to make the scene look like a night scene. Again the reason to light is for better shadows, to make the darker parts of the scene appear very dark relative to the foreground and a high level of contrast will make it look like night. Consider a bright moonlit night, faces will be bright compared to everything else.
So in cinematography, very often the reason to add light is to create shadows and contrast rather than to simply raise the overall light level. To make this easier we need to think about reflections and how the light that we are adding will bounce around the set and reduce the high contrast that we may be seeking. For this reason most film studios have black walls and floors. It’s amazing how much light bounces of the floor. Black drapes can be hung against walls or placed on the floor as “negative fill” to suck up any stray light. Black flags can be used to cut and control any undesired light output from your lamps and a black drape or flag placed on the shadow side of a face will often help increase the contrast across that face by reducing stray reflections. Flags are as important as lights if you want to control contrast. Barn doors on a lamp help, but if you really want to precisely cut a beam of light the flag will need to be closer to the subject.
I think most people that are new to lighting focus too much on the lights themselves and don’t spend enough time learning how to modify light with diffusers, reflectors and flags. Good video lights are expensive, but if you can’t control and modify that light you may as well just by a DIY floodlight from your local hardware store.
Also consider using fewer lights. More is not necessarily better. The more lights you add the more light sources you need to control and flag. The more light you will have bouncing around your set reducing your contrast and spilling into your otherwise nice shadows. More lights means multiple shadows going in different directions that you will have to deal with. Instead of using lots of lights be more careful about where you place the lights you do have, make better use of diffusion perhaps by bringing it closer to your subject to get more light wrap around rather than using separate key and fill lights.
This is something that comes up a lot and I get many questions about. In part because I designed the MTF B4 to Canon, FZ and E-Mount adapters. Budget adapters that allow you to use a 2/3″ B4 ENG lens on a Super 35mm sensor by using the lenses 2x extender or on a center crop sensor without the 2x.
The question is… what will the pictures look like?
The answer is… it depends on the lens.
Not a very helpful answer perhaps, but that’s the truth of it. Different lenses perform very differently. For a start I would say forget 4K. At best these lenses are suitable for HD and you want to have a great HD lens if you want good HD pictures.
But what about the “look” of the images? My experience is that if you put a wide range ENG zoom on a S35mm camera the look that you get can be best described as “2/3″ ENG look with maybe shallow depth of field”. Lets face it, ENG lenses are full of compromises. To get those great big zoom ranges with par-focal focus there are a lot of glass elements in those lenses. Lot’s of elements means lots of places where CA and flare can occur. The end result is often a lowering of contrast and color fringing on hard edges, the very same look that we are used to seeing on 2/3″ cameras. Typical cine or DSLR lenses tend to have simpler optical designs. Prime lenses are normally sharper and show better contrast with less flare than zooms due to there simpler internal design.
So don’t expect to put a typical B4 ENG lens on your S35mm camcorder and still have that crisp, high contrast digital cinema look. Of course B4 zooms are handy for the ability to zoom in and out through huge ranges while holding focus. So an adapter and lens may well make your S35mm camera more versatile. But if you want the best possible images stick to cine style lenses, DSLR lenses or zooms designed for S35.
Sony have released a firmware update for the 18-105mm lens that is available as a package with the FS5. The update addresses some of the focus tracking issues that some lenses appear to have. To update the lens firmware you need to go to the support page of Sony consumer: http://www.sony.co.uk/support/en/product/SELP18105G
and download the update package. You will need to have the lens mounted on a camera and the camera connected to a Mac or PC. Full install instructions are provided after you click on the Mac or PC download link buttons.
