The Sony FX6 is Full Frame – Sometimes!

Perhaps I’m splitting hairs here a little bit – and I still think the FX6 is an amazing camera. But the more I look at it’s different scan modes and recording mode the more I’ve realised that it’s only actually “Full Frame” in few certain settings. 

When the FX6 is set to UHD and operating from 1 to 60 fps then it’s full frame and the whole width of the sensor is used. Put a Full Frame lens on the camera and you get the same FoV as an FX9 or any other camera with a similar sized sensor.

But if you want to shoot 4K DCI then something strange happens. Switch the FX6 to 4K DCI and the sensor is cropped/windowed by 5% and instead of the field of view becoming 5% wider as happens on most cameras, it instead  becomes 5% narrower. In 4K DCI the FX6 is very slightly less than Full Frame. 

To shoot at more than 60fps the camera has to be in UHD. 60 fps and below it’s full frame but when you go above 60fps the image is cropped even more, this time by 10% so the FoV gets 10% narrower.

If you want to record UHD Raw at any frame rate the image is also cropped by 10% so UHD with raw out at 30fps results in a 10% narrower FoV than when you are not outputting raw. When you enable raw at 4K DCI raw it’s a 5% crop.

So while none of these crops are huge it is worth noting that the FX6 is actually a little less than full frame more often than not!

Just to put all this into some perspective the FX9’s Full Frame Crop 5K mode involves a 17% crop. The FX6 outputting UHD raw or recording UHD at more than 60fps is a 10% crop. That’s not a vast difference. In these modes the FX6 is closer to the FX9 5K mode than to Full Frame.

Why is this? Well the FX6’s sensor is 4.2K pixels across. In the “normal” UHD frame rates (up to 60fps) the full 4.2K is read and downscaled on the fly to 3840 x 2160 UHD.  When you shoot 4K DCI there is no downscale and instead the sensor is read out at 4K and the extra 0.2K of pixels at the edges of the frame are not used – 0.2K being 5% of 4.2K and thus you have a 5% crop and the FoV becomes 5% narrower in DCI 4K than in UHD.

When you shoot above 60 fps then the sensor is read directly at 3840 pixels rather than 4.2K to make the readout simpler and faster. So now we are reading 0.4K fewer pixels from the sides of the sensor which is 10% of the total pixels and we get a 10% narrower FoV above 60fps as a result.

As I said at the start, perhaps I’m splitting hairs. I certainly don’t think this detracts from the FX6 in any significant way. But if it’s a camera you are thinking of getting, you should be aware of this.


Differences Between FX9 and FX6

Here are some of the differences I have so far identified:

FX9 FX6
6K Full Frame Sensor (20.5 megapixels) 4K Full Frame Sensor (10.2 megapixels, large pixels)

6K Oversampled Full Frame 4K recording, max 30fps. 5K up to 60fps, 4K up to 60fps

More rolling shutter when using 6K FF (more pixels to read).

4K Scan for Full Frame UHD recording upto 60fps.

Compared to the above:-

10% crop when recording UHD above 60fps.

5% crop if recording or outputting DCI 4K.  

10% crop if outputting UHD raw.

FF Crop 5K Scan max 60fps.  No
4K Super 35mm Scan max 60fps. HD Super 35mm Scan max 120fps (the camera can go to 240fps using S&Q but the quality is slightly reduce above 120fps).
2K Full Frame Scan max 180fps (IQ reduced). No
2K Super 35mm Scan max 120fps (IQ reduced) No
2K Super 16mm Scan ( coming in v3 firmware) No
No Clear Image Zoom (1.5x in 4K, 2x in HD) But not available above 60fps or when outputting raw. Also Face/Eye AF disabled when using CIZ.
Interlace recording and output, full 50i/60i support using FF crop 5K scan or s35 4K scan. Can use FF 2K scan but IQ is reduced. No internal interlace recording (interlace output is possible when recording 50p/60p)
No UHD 100/120fps internal recording.
Shooting above 60fps requires reduced quality 2K scan mode (currently waiting for s35 scan 120fps UHD raw to be released). Shooting up to 60fps uses full sensor scan. 60 to 120fps  1:1 sensor scan (10% crop).120 to 240fps HD uses reduced quality sensor scan.
Highest frame rate that can be recorded internally 180fps.  Highest frame rate that can be recorded internally 240fps. 
Highest frame rate that can be recorded via raw 180fps (optional XDCA-FX9  required) Highest frame rate that can be recorded via raw 60fps.
No Auto Focus in S&Q Auto Focus works in S&Q when the S&Q frame rate is a direct multiple of the base rate. So base rate 23.98/30/60fps AF works at 23.98/30/60/120fps. Base rate 25/50fps AF works at 25/50/100fps.
If base rate is 24fps then AF does not work in S&Q.

Common FX6 Questions.

So these are some of the questions I keep being asked about the FX6.

What will be in the box?

I believe the box will contain: Camera, Top Handle, Hand Grip, LCD + LCD Shade, 1x BPU-35 battery, charger, power supply.
 
You will need to supply: A suitable lens and recording media, either CF Express Type A or SD v30/v60/v90 (I recommend v90). The camera can act as a card reader if you don’t have a reader for the CF Express cards or SD cards, there is a normal USB-C connector on the rear.

Will there be a kit with a lens?
 
I have been led to believe that there won’t be a kit with a bundled lens from Sony in Europe. However some dealers may choose to put together a bundle deal or package for you and there “might” be a kit option in the USA with the Sony 24-105mm lens.

What one lens would you recommend?
 
This is a tough one to answer as it depends on what you need. The Sony 28-135mm power zoom is a great lens, but it’s bigger than the camera! The Sony 24-70 f2.8 GM is a beautiful lens and one of the lenses I have on my FX9 almost all the time. But if I had to pick just one lens it would probably be the Sony 24-105mm f4. You get a decent zoom range and good optical quality. f4 on a full frame sensor gives reasonably shallow depth of field.
 
What Cards should I get?
 
See my other post about this by clicking here.
 
Does the Auto Focus work when using S&Q?
 
Yes, in most cases it does, but only when the S&Q frame rate is a neat multiple of the base frame rate. If the cameras base frame rate is set to 23.98p, 30p or 60p then it works at UHD 120fps or HD 240fps, but not at 100 or 200fps. If the camera base rate is set to 25p or 50p then the AF only works at UHD 100fps or HD 200fps but it doesn’t work at UHD 120fps or HD 240fps.

Does the camera reboot when changing frame rates?
 
The FX6 reboots when you switch between base frame rates except when switching between 25p and 50p or between 29.97p and 59.94p. When in S&Q it does not reboot when changing frame rates. It is only base frame rate changes that cause a reboot (about 3 seconds).
 
How quickly does the FX6 start or reboot?
 
Very quickly. It takes under 3 seconds to start from off. You can actually start recording in around 2 seconds, before some of the LCD overlays have finished coming on.
 
Does it have clear image zoom?
 
Yes it does. I didn’t spot this initially as it’s buried in the technical section of the menus. In UHD it provides a 1.5x zoom, in HD a 2x zoom.
 
Could I use Clear Image Zoom in UHD/4K to work with super 35mm lenses?
 
Short answer is yes, in some modes. The longer answer is maybe. Be aware that as soon as you use Clear Image Zoom you will lose the cameras excellent Face/Eye AF and clear image zoom is not available when shooting above 60fps or when outputting raw. As you need to typically use between 1.4x and 1.5x zoom to eliminate all vignetting or edge distortions there is a small but noticeable loss of image quality. It’s slight, but the images are a bit softer and look a touch more processed. Any noise becomes more noticeable as the noise grain gets bigger. It’s not horrid, but the image definitely loses a little of the crispness and clarity that it normally has. This isn’t really a surprise as by the time you have zoomed in by 1.4x you are upscaling around 3.2K to 4K. You could use it if you really need to, but it’s a shame to use it as it just takes the edge off what are otherwise exceptionally good images, it’s definitely not comparable to the FX9’s proper 4K s35 mode. 

Does it have Center Scan? 
 
No, it does not have a 2K center scan as found on the FS7 or FS5. This is because the FX6 has a 4K full frame sensor, a 2K crop from this would be too large to be used with super 16 lenses and too small to be useful with super 35mm lenses.

Can you use both the SDI and HDMI at the same time?
 
Absolutely, yes. And you can even have HD on the HDMI and UHD on the SDI if you want.
 
How long do the batteries last?
 
The supplied BP-U35 battery will run the camera for a bit over 90 minutes. A BP-U60 will run it for between 2.5 and 3 hours.
 
Can you use LUT’s when shooting at high frame rates?
 
Yes, LUT’s in CineEI  work at all frame rates and resolutions. I have yet to find a case where they do not work, including user LUT’s. Because LUT’s are always available there is no viewfinder gamma assist function in the CineEI mode, only when using the HDR shooting mode to shoot using HLG.
 
Does it have a LANC port?
 
Yes, it has three. One 3.5mm 4 pin mini jack that the handgrip plugs into on the side of the camera, this is different to the FS5/FS7 type connector. On the rear of the camera there is a 2.5mm 3 pin mini jack that is compatible with the FS5 or FS7. Plus the larger USB style multi-port that the FX9 remote handrip uses (but at the time of writing the FX9 grip does not work with the pre-production firmware).
 
Can I see all 4 audio channels on the screen at once?
 
Yes, since firmware version 2 you can see meters for all 4 channels on the LCD at the same time, but the meters are very small. You can also see all 4 channels on the status pages and use the touch screen to adjust the recording levels for channels 3 and 4. This is also where you will find the volume control.
 
Does it have Clear Scan or ECS shutter?
 
Yes it does, this is very useful for shooting computer monitors or other screens and eliminating any rolling bands that may move up and down the screen. ECS is in the shooting menu under Shutter.


I will add to this list as more questions get asked.

Which Cards Actually Work with the FX6?

The FX6 takes both SDXC cards and CF Express Type A cards.

Sony recommend using a CF Express Type A for the UHD 120fps. For 4K. The CF Express card support all frame rates, but they are expensive, as is the card reader.

For UHD XAVC-I up to 60fps Sony say you can use v90 SD cards, for some of the XAVC-L UHD frame rates Sony support v60 SD cards and for HD you can use a v60 or v30.
 
The camera won’t stop you from trying to use a v90 (or even a v30) SD card at all frame rates and with all codecs. But if using a card outside of the Sony recommendations you get a “not guaranteed media” warning.
 
For example when trying to use a v60 to record XAVC-I at 60p or a v90 to record 100/120fps the camera will try to record but if the card can’t keep up you will get flashing tally lights followed by the camera dropping out of record and a “Recording Halted” message. In my testing most of the time the camera just displays the recording halted message and you have to press the menu button or OK button to remove the message, then you can try to record again. But around 30 to 40% of times, especially if it is a second attempt to record on a card that is not fast enough, after the recording halted message the card capacity will go to zero and the record tally lights will continue to flash until you remove the card.  You will not then be able to use that card until it has been restored and in most cases you will lose the last clip shot as well as other clips where the recording was halted. In some cases you can lose everything on the card.

As a card fills up it becomes significantly slower. So a card that is fine when only partially used may cause problems as it fills up. In addition as cards get older they slow down as the memory cell wear leveling has to skip extra blocks or cells. So a card that works today may not work tomorrow.
 
My advice: Use the cards Sony recommends. You are playing with fire trying to get away with other cards. The big risks are a: losing footage and b: ending up with no media as the capacity has gone to zero.

Get a CF Express Type A if you want to shoot UHD 120fps. For everything else SD v90 will work fine.

Thoughts on the FX6

I’ve written a review of the FX6 that you can read here.

https://sonycine.com/articles/the-new-sony-fx6—the-definitive-review-by-alister-chapman/

But I thought I would also write more of an opinion piece here. What do I really think about the FX6 and also where does it fit in the grand scheme of things.

Sony FX6 4K Camcorder

 

First off, it is a brilliant little camcorder. But it has to be. There is huge pressure from ever better mirrorless cameras and ever better larger cameras. Red’s Komodo is similarly priced and offers an interesting option if you are a film maker that doesn’t mind adding your own viewfinder etc..

Sony really have packed an amazing set of features into the FX6, S-Cinetone, LUT’s, CineEI all make it a very, very interesting camera for film makers and corporate video producers alike. But the FX6 hasn’t been aimed at broadcasters, the lack of interlace recording and the lack of a streaming function make it less desirable for news and current affairs. That’s more of the realm of the FX9.

The FX6 is likely to be a huge success. I know I will be getting one. It will be fantastic for my trips overseas where size and weight are important, and I can’t wait to try to shoot the Northern Lights with it. The low light performance is indeed very impressive but this could become a problem area for it.

When you have a camera with a base ISO of 12,800 I think there will be an expectation that you won’t need to light, that it will produce brilliant pictures no matter how dark it is. But you have to remember that one of the keys to getting good results in any light level is not the amount of light but the amount of contrast. You will still need to think about how you add or control the light in your scenes and it will be all too easy to blame the camera when you don’t get great looking pictures on a pitch dark night shoot with no light to add some contrast.

I also think that the gap between 800 ISO and 12,800 ISO is too big. At 12,800 ISO there is so little light that something called Photon Shot Noise becomes an issue. It can make the mid range noisier than you would like it to be, even when you are correctly exposed. And ND filters won’t help as they reduce the light hitting the sensor and the relative photon shot noise increases. But if you do want to shoot in very dark conditions, then the FX6 performance is indeed impressive.

When I had the pre-production FX6 I took it up to the Lake District, shot interiors at home and spent a couple of days examining the images with charts and test scenes. What I learnt was that it is a very easy camera to work with. Changing settings via the touch screen is quick and simple. The single menu button that first brings up what are referred to as status pages on the FX9 and then with a long push brings up the main menus is brilliant. One button for both. No fumbling around going from the status button to the menu button as on the FX9. The auto focus works brilliantly, and I love having a waveform display with the zebra levels clearly indicated on it. It makes judging exposure easy and reliable. Set the zebras to 61% and if you toggle the s709 LUT on and off you can check the brightness of a white card when looking at the S-Log3 or skin tones when looking at the s709.

Going back to the Auto Focus for a moment – Yes, it does work in S&Q and even when shooting UHD 100 or 120fps. BUT I did find it less responsive and slower to respond when shooting at 120fps, it definitely didn’t seem as good as when shooting at normal frame rates. And there are actually a few limitations, AF only works when the shooting frame rate is a direct multiple of the base frame rate.

it also has some other oddities, like the field of view when shooting 17:9  4K DCI is narrower than when shooting ordinary 16:9 UHD because of the way the scan modes work. If you want to output raw the FOV is narrower than when recording UHD internally.

I’m really looking forward to using it on gimbals, lighter weight sliders etc. For those on a tight budget having a lighter camera means you can also save money on your support gear compared to a heavier camera. I think I’m going to enjoy shooting with the FX6 and I’m sure many others will enjoy it to.

And that’s the thing. It’s an easy camera to use, it delivers a beautiful image with very little effort. This is one of it’s big strengths and why I believe it will convert a lot of mirrorless DSLR shooters over to a “proper” video camera. It brings the ease of a built in variable ND filter, LUT’s and other great exposure tools for shooting log, good battery life and pro audio all together in an easy to use package at a good price. At the same time it isn’t so big that you need huge pro tripods and expensive heavy duty support equipment.

It will also appeal to users of Sony’s Venice digital cinema camera to get into places you simply can’t get the bulk of a Venice or as a crash camera for high risk shots. The pictures match close enough that it won’t stand out in a finished production as an obviously different camera.

One issue is the lack of audio inputs when the top handle is removed. This does seem to be an oversight. Gimbal users will find it frustrating I’m sure. Time to break out the external audio recorders, at least the built in scratch mic will help with audio sync. Maybe someone will figure out a way to get audio into the camera body via the connector that the top handle plugs into. The other alternative is to take the video out of the FX6 to an external recorder that also has an audio input such as many of the Atomos recorders.

So where does this leave the FX9? The FX9 is a great camera. It is worth remembering that the FX6 really is Full Frame only (unless you are happy shooting HD in it’s super 35mm mode). So users of normal 35mm PL lenses or APSC lenses will be better off with the FX9 with it’s greater choice of scan modes including 6K FF, 5K crop FF and 4K s35. In the next firmware update the FX9 will also get a 2K s16 center scan mode and it will be able to use the Sony B4 lens adapter with 2/3″ ENG zoom lenses. I still love shooting with my super 35mm Fujinon MK’s on the FX9, it’s a great combination. The FX9 also has no issues with interlace, so news shooters that still need 1080i will want the FX9 and not the FX6. I have every intention of getting an FX6 but I have no plans on parting with my FX9. Because the images from the two cameras look virtually identical they will compliment each other nicely (anyone want to buy my FS5??). 

And that for me is the thing: Two cameras for two different types of shoots, but both look the same, so I can just use whichever is the most appropriate for the job without any concern. 


Sony FX6 Launch

Sony will launch a new small 4K handheld camcorder – the FX6 on Tuesday the 17th of November.

Sony FX6 4K Camcorder

To find out more about this new and very exciting camcorder you can watch the launch event via Instagram. After the launch event I am hosting a Q and A on Instagram. I’ve been lucky enough to have shot with the camera and have extensively tested it, so tune in to the Q&A to learn more. There is a lot to like and I am certain this camcorder will prove to be extremely popular. The Instagram session will be here: https://www.instagram.com/sonyprofilmmaking/

Then on Wednesday the 18th I will be presenting a webinar on the FX6 for Visual Impact in the UK at 11.00 GMT: https://www.visuals.co.uk/events/events.php?event=eid1748059180-892

 

 

 

Then once the initial launch dust settles I will bring you more information about this exciting new camera including tutorials and guides.

Sony Introduces Cinema Line and teases the PXW-FX6

Sony are teasing the PXW-FX6.

So there is no IBC show this year and instead Sony are doing various online sessions with the latest news as well as guides to some of the most recent products and firmware. 

Today’s news is of new branding for Sony most recent digital cinema cameras, Vence and the PXW-FX9. These cameras are now members of what Sony are calling “Cinema Line” and in addition there are pictures of a smaller camera not surprisingly called the FX6 that looks like – well – what you would expect an FS5 replacement to look like. 

In the past Sony’s digital cinematography cameras were denoted by their “Cinealta” badges. But to some extent this became somewhat confused as all sorts of cameras like the Sony EX1 and Venice were classed as Cinealta. So what exactly is the new Cinema Line?

To quote from the Sony Press Release:

“At Sony, we celebrate and have the deepest respect for filmmakers, cinematographers, and storytellers. With Cinema Line, we’re tapping into our DNA from both the film industry and digital imaging prosumer market and combining it to develop new creative tools. This line of products will enable creators to push their creative boundaries further and capture the emotion in each and every frame.” says Claus Pfeifer, Head of Connected Content Acquisition, Media Solutions, Sony Professional Europe.

So, I’m not really sure! My guess is it’s a set of products, not just cameras  aimed at what we now tend to call Cinematography rather than broadcast television or industrial video applications. Of course there is a huge amount of cross-over between all these different genres these days, so I’m sure the Cinema Line products will be used all over the place.

My main hope from this is a more unified look from any cameras in the Cinema Line. My big hope is that the FX6 will have S-Cinetone and that when you shoot S-Log3 with the FX6 that it will look like the S-log3 from the FX9 or Venice. This will make grading and post production easier where you mix and match cameras.

What about the FX6?

I don’t have any more solid information than you right now. We can expect it to be Full Frame, to shoot 10 bit 4:2:2 4K using S-Log3 and to probably have a raw output. As the FS5 is based on the A7S hardware with an F5 sensor it wouldn’t surprise me if the FX6 was based on the A7SIII hardware with the FX9 sensor perhaps. So it might have 4K at 120fps. From the pictures it appears to only have 2 channels of audio and the cover for the card slots (there must be 2 as there is a slot select switch) doesn’t look big enough for two XQD or CF Express Type B, so I would guess that like the A7SIII it’s SD cards or perhaps CF Express Type A.  Another thing I notice in the pictures is a lack of an AF/MF focus switch and in particular no menu navigation controls, so I will guess the LCD is a touch screen and it will rely on this for a lot of function control and menu navigation. But this is just speculation, so don’t hold me to any of it!!!
