Official at Sony US: 14 Bit RAW coming to A7sII, A7rII and “additional” cameras. What benefits can you expect?

sony_14_bit_a7sII_A7rII_'

After AlphaUniverse als Sony.com confirmed the news: 14 Bit uncompressed RAW files are coming to the A7sII (included right from shipment start) and A7rII (via fw upgrade). The big question now is…what kinf of improvement can we expect to achieve with the new RAW files?

The “possible” benefits lists:
– more shadow data (increased dynamic range)
– no compression of tonal differences on near high-contrast edges. No more posterization effects and improved image quality in high-contrast night scenes.
– greater processing latitude
– Less complains on SAR and other websites 😉

Possible drawback of the new 14 Bit RAW:
Of course you get much bigger files to deal with. And we have to see how fast (or slow) the Sony A7sII and A7rII processor can deal with that amount of data. And we don’t know how slow that processing will be on older cameras (A7, A6000 or so if they will ever add 14 BIT to those).

Reminder: Her eis an image from Rawdigger.com showing the posterization effect on Star Trails:

        1. Exactly. The default position that people who legitimately have a complaint or need and are vocal about it are ‘trolls’ is nonsense. This has been far too long in coming, and wouldn’t have come now if so many people had been so vocal about a very expensive pro level camera throwing away potential IQ unnecessarily.

      1. Yes, indeed there are some average users like myself who bought the NEX-5, NEX-6, A7r and the A7r mk2 at the moment they were released. I like their small form factor with large sensors… and the image quality is great so why not ?

  1. The quality “improvement” I foresee is that my images are likely to come from one of these cameras in the future.

    1. That’s only one benefit though.
      Whereas in reality, people like myself get to rest easy knowing we can use every last ounce of DR from this camera. – FTW!

  2. A7 sieres and my a6000 🙂 also 5100 , i wanna buy a7rii or a7sii i shot both video and photos but most i didnt have enough light i shot with iso 12800 in most pictures , and in video 4k there are big diffrent ? Also pictures with little iso such as 100 ? Thanks

  3. I doubt the A7s or A7sii will have much of a problem with size or processing times. I shoot on RAW for my A7s all the time and the file sizes are very small for raw. 12MP isn’t huge, even without compression we’re looking at 5-7MB raw files, not 20+ something files. The A7r/A7rII however might be problematic. Probably 40-50MB files here. That will fill up a mem card fast!

    1. …which people will complain about. Perfect for sony, they’ll drop the A9 with twice the processing power for even more $$$. Win for everyone.

    2. An uncompressed RAW A7R II file will be at least 73MB, and that’s only if the 14 bit values aren’t aligned to 16 bit. If they are (like Nikons uncompressed RAW) and are aligned to 16 bits, then an uncompressed RAW will be over 84MB. If there’s an uncompressed option, from the Nikon stats for that option, that might get you down to about 50MB.

    3. Thus far as my testing went 41-42 MB is the size of the standard compressed RAW files with the A7r mk2. I am wondering how large the un-compressed RAW will be… and how slower will the transfer to the SD card…

  4. I’m sure we’ll see complaints about something. The A7rII can be slow writing to the card at times – larger files are going to make that worse.

    Pixel peepers will still find faults with images and things to complain about when using Rawdigger. Most will never see a difference.

    Hopefully it reduces the chatter and we can move on to other things that can be addressed with a FW update.

    1. As the press release indicates, you can simply turn it off.
      My guess is that it will be assignable to custom functions. (on/off)

    1. For 1080p or 4k? Because they’re having trouble putting 422 in the$5600 FS5. I doubt a $3000 or so A7 camera would get it.

      1. Hilarious. Yeah, people care- probably not those on this forum. DR and resolution being limited? Might want to check your specs. on that.

        I’ll tell Sony to put an A77II aside for you. You know, for when your ready to handle the beast.

        1. I’ve been the proud owner of an A99 since it was introduced, I know the camera quite well. That said, I can pull 4 stops of shadow recovery at best with this sensor and that’s saying alot in terms of NR and post processing.

          That said, my A7R II is on the way. Was shipped out express this morning from Ontario. – dancing banana 🙂

          1. Is it the sensor?
            What about the body and the mount did you really need to change or were you forced to do so ?

          2. Well then, please report back once you get it! I never push my files that much, but I am curious if this 42MP sensor is worth getting all giddy about.

        2. This is really concerning,
          people using Amount a month ago are turned into Amount haters only by dropping $3.5k for something built to hook Canikons and 4k wonabe Spielbergs.
          There is really need for Psy help on this site indeed.

  5. I don’t see why there will be more details in shadow areas. That was never the problem. The issues that do exist are in very high contrast areas over very small areas, but for the most part evident only if you provoke things (like underexposing and pushing in post).

    I also don’t see why it would increase DR either.

    1. It won’t likely increase DR in any meaningful way, though it will certainly increase the amount of usable DR to users which would have otherwise been limited by the presence of artifacts at some particular point. ie, +/- 5 stops shadow recovery

      1. You are both right. The existing compression algorithm only introduces artifacts when there are two pixels in a 16-pixel blocks that have a brightness difference of more than 128 ADC counts. This only happens on a small fraction of the blocks in most photos. Even on blocks that do have quantization artifacts, they are only really visible when they occur against a dark background.

  6. No mention of the A7II ? Up until a few weeks ago this was the latest and greatest camera from Sony, now it doesn’t even get a mention. I’m sure it’s covered under “others” but still, it bothers me a little how quickly Sony cameras move on.

    1. Unfortunately the A7R II has rather killed the appetite for the A7 II. The latter is probably feeling quite lonely as I think a lot of people are either summoning up the courage to spend a fortune on the A7R II, hoping it’s going to drop in price soon or waiting for what surely must be the inevitable A7 III with a BSI sensor. I’m in the last camp (a 24MP A7 III with all the other advances of the A7R II would suit me perfectly).

      I think the advantages of the A7R II over the A7 in the areas of (especially) AF and third party support plus the video capabilities are simply to attractive for many people to settle for the A7 II.

      1. A7Rii and A7ii should get a baby:

        A7Rii:
        -BSI
        -4K internally in FF and crop
        -AF

        A7ii:
        -about 24mp (but higher ISO)
        -price 🙂

      2. I’d agree with that, although it doesn’t make me feel any better about it or my investment in the Sony system. For all those people forking out $3,200 for an A7RII, this time next year you’ll probably be in the same boat when the the A7RIII comes out and makes your RII outdated. I fondly remember when spending $$$$ on a Canon camera meant you were using the latest and greatest for several years.

        Yea, I would actually be happy with an A7III with 32MP BSI sensor + the newer EVF. That’s about as large as I would need for a while, I used a A7RII on loan for 2 weeks and the images were excellent, but larger than I needed for 90% of my usage.

        Resale value does concern me with Sony though. We seem to pay as much as any other DSLR system, but the value degrades like a common point and shoot camera.

        1. A7RII was going- brand new- a few “the box got dinged” for 2800.00 on Amazon two days ago. Now let me see:

          If you sold it now you’re looking at 2800.00 my guess. Add tax, ebay fees, etc. It’s about 950 in loss.

          The A7R is still an incredible value. I’m seeing it go for 1k lately. That’s just insane. Yeah, I’ll wait for some depreciation to hit this A7RII first.

          1. I’ll do the same. Probably grab a 2nd hand A7RII when they drop to around $2,500, the catch is that by then my A7II is probably only worth about $500, so i’ll be forking out a lot of upfront cash.

          2. That was a major motivator on me selling the A7- that thing was an anchor. Stashed the cash for later upgrade.

          3. Guys…. it works like this:
            you either make money with your cameras and you do not care if after 2 years they are worth peanuts, so you kindly pass them to your starving assistant, or you take another hobby.
            Tennis is a good start for example: with an A7r/s II money, you can buy 15 of the best racquets, a truck load of balls and make everybody believe you are an ATP player when you show up at the court for a few rallies.

        2. This is surely the result of GAS????!!!!
          If you were happy to buy the A7RII then what exactly is there that would suddenly make you unhappy when an upgraded A7RIII comes along?
          If you were hoping for better specs in the A7RII then why did you buy it in the first place?

          I’m still waiting for any ideal replacement for my trusty old A700 which is still producing great pictures. While I’m definitely suffering from GAS, I’m managing to keep it in check because I only have SO MUCH money to spend on a new camera and lenses and I want to be sure I’ll be GAS-free for a long time to come before committing to anything new. The A7RII ticks all the boxes except one – price. So I’m quite happy to wait. I doubt that I’ll take a lot better pics with a new camera. Maybe the images will improve in technical quality with new lenses but that’s about it.

          1. Huh? I think you misread my post. I wont be buying either the RII or the RIII until they drop significantly in price, and probably second hand. The RII specs are just fine, its just too expensive right now for a camera that will degrade in resale value at such a fast rate.

            There is definitely some GAS going on there for sure, but there is a price limit before better judgement kicks in. $3,200 is well over that limit for me. Had they released the A7RII for $2,500, I would already own one, even though I really don’t need one. GAS would be in full effect.

        3. With Sony it seems that innovation goes unabated and upgrade cycles are about a year or two. This is very short when compared with Canikon for instance but people are free to upgrade at each iteration, every two iterations or wait years… to suit their needs, means, etc… I think people should keep in mind that a better camera does not mean better pictures as the result is very heavily dependent on the photographer’s abilities. A good photographer with a crap camera may still manage to pull out better pictures than someone who does not know how best to compose and use the light even equipped with the best camera, lenses, etc…

          Depreciation: The trick is to buy your cameras where these are sold cheapest and resale second hand at locations where these still command a high premium… Yes, yes; it’s possible for people who travel a lot. By this way you reduce your cost of ownership or depreciation…

        4. “I fondly remember when spending $$$$ on a Canon camera meant you were using the latest and greatest for several years.”
          Sure! I did resell all my canon gear 7 years ago for good money. Some lenses were 3/4 years old and lost less than 10/15% value.
          Yet, you can only be found of those years, because even if canon gear may retain the resell value better than any other brand….
          well, the are not making anymore the latest and the greatest, but not even close.
          And it has been a while now.

      3. I disagree heavily.

        Technology increases are a well known thing, and not that many people wait out eternally for the next gen. Also, the A7II has plenty of amazing features for like half of the cost of the A7RII. Seriously…

        1. Maybe, but I for one am waiting, especially as support for A-mount with the LEA-3 adapter is an important point. I’m in no hurry. Other people will have different priorities,

  7. A7 seires and rx sieres and a6000 also a5100 ,, i have rx100ii and a6000 , i wanna buy a7rii or a7sii which one is better ? I shot both video and photos , half times i shot with 12800 iso , in 4k video the difference is big ? , also in pictures in low and large iso , thanks

    1. Sounds like you need the s2 since you’re shooting so much in the dark. For most other uses, the r2 would be the better camera, however, as stills quality will be better in all but the darkest conditions, and video will be about the same, except in the darkest conditions.

    1. Exactly ! I am happy with my A7r and A7r mk2 as they are but curious about the new stuff since people complained like crazy about it.

  8. I’m confused – as far I know, the supposed problem has been with not using a lossless compression, not that RAW files are compressed. Don’t others use a lossless compression, as opposed to not using any compression?

    1. The problem is that the compression algorithm that Sony chose throws away some meaningful data bits in the compression process and there is no way to accurately recover them in the decompression and playback.

      The existing system performs a compression on blocks of 16 pixels at a time. If the difference between the dimmest and brightest sample in that block is more than 128 A/D counts, the algorithm shifts all the values down and throws away the bottom bits. This results in weird compression artifacts that are most noticeable when there is a single very bright pixel next to a nearly-black background. Star trails and fireworks are examples where the artifacts really shows up.

  9. I really hope they extend this back to the A7ii and maybe even the A77ii (or other Bionz X powered cameras), as those are the two I use the most. I tend to try and maximize the dynamic range in my images, especially when shooting long exposures, fireworks, astrophotography, landscapes and the posterisation can really become visible in high contrast areas, it’s especially noticeable in Fireworks shots.

    I don’t mind compression as long as it’s lossless and hope they still give us the option for the compressed lossy 11+7 RAW – it’ll be nice to see in Sony cameras but I really hope they release this update for other still-current Cameras like the A7ii.

  10. Do we know the full fidelity 14-bit raw files will be uncompressed? They could still be compressed (just compressed losslessly), which would reduce filesize. Even if uncompressed, this is welcome news.

  11. I vote for a complete ban on the use of the “whine”, “whiners” and “whining” in comments. That really gets old.

    1. I vote for a complete ban on “whiners” and “whining” in the comments. It’s already old. There’s nothing wrong with complaining or having an opinion but some people here post the same crap on every single post, not matter how vaguely related.

  12. I love the way you can turn it off or on (implies it affects buffer) So when you’re shooting landscapes, architecture etc where speed is not an issue but quality is than you can shoot away in 14 bit. Events, nature, sport photographers might benefit from it been turned off but than the files wouldn’t be pushed as much usually. Quite clever.

    1. This is what many thought should have been the ideal first solution, because not everyone has the need for throughoutput speed.

  13. Image quality improvement will primarily be in the comment sections of blog posts, and forums across the web. Less ‘noise’ about compressed raw files

    1. Bah, it’s definitely visible when you process your raw files heavily. I “just” have an a6000, but I have noticed posterization and artifacts when processing my raws. I like doing night photography a lot. It was never a big enough deal for me to get a different camera, but nevertheless annoying, and I’d be really happy if Sony had a firmware upgrade for the A6000 too.

  14. I just hope they extend this courtesy to us a77ii users. I don’t think I’ve ever seen any compression issues with mine, but I would enjoy having the option to compress or not. I guess time will tell, but I’m not optimistic about it.

    1. You misunderstand something. The Admin of this website is the one who bitched about this the most.

      He was part of the problem.

    2. People will still find ways to complain.

      I just hope that the firmware update will involve an addition to the menu such that the user can select if he wants the compressed RAW or the uncompressed RAW. I would certainly not update my A7r and A7r mk2 firmwares if there was no option to choose compressed or un-compressed RAW at my own will.

      Now I wonder if the uncompressed RAW will have that much a visible impact on the image quality of these wonderful a7 series cameras. Finally we will know if the whiners are correct or if they are just pre-Madonnas…

      Assuming that the un-compressed RAW will increase the cameras dynamic range, will DXO perform re-tests ?

    3. He may not be that happy about the whining stopping, since there have not been more rumours to post about for the past 2 years.

  15. I love my Sony A7II for what it can and does for me, so I do not need a new camera for a while. I used to have a Sony A7, and was happy with it other than the shutter button position and the mount was a little loose with heavier lenses. Must say that Sony A7II has closed the last holes, so from here, there is absolutely no need for a Sony A7RII …..

  16. Has anyone ever bought this comic wideangle adapters ? The idea is nice , less weight and practical since one uses wide and ultra wide so rarely, but how good are they ? Anyone ? Thanks

  17. I am pretty sure they will add to A7II as well, because what Sony are saying is A7SII will have it from the factory, after that they will add it to other cameras STARTING with A7RII, so next should be A7II and maybe RX10II and RX100IV.

  18. The speed is very easy to estimate. Imaging-resources had measured that 7RII’s buffer can hold about 23 frames, then continuous shooting speed falls down to 0.85 fps and clear time is about 24 seconds. Uncompressed 14bit RAW for A7R would be ~70 MB (which is what D810 outputs), would be bigger for 7RII.

    Indeed lossless compression is more useful then just uncompressed raw.

    1. however for Nikon they both use lossless and uncompressed words to talk about their lossless RAW files. So if they can handle continuous shooting of 14bitss lossless RAW why not Sony. Maybe Sony should sell their sensor to Nikon while Nikon would sell their chip to get faster image processing 😉

          1. Are you using 5 yrs old cf or mars technology uhs 1? On earth uhs I topped out at 105mb/s. Cf can go 150-160 mb/s.

        1. Not even. UHS-I is pretty close to top CF speeds. Sony tops out ~35MB/s regardless of how fast the card will write. That’s USB2.0!

          1. I never said it did Ilan. UHS-I is the interface between the card and the SD card slot. The card slot then has to interface with the cameras CPU. THAT interface is not UHS-I it is something else. Often some flavor of USB. Given the max speeds people are reporting with event the latest Sony cameras it seems that the card slot is connected to the CPU over USB 2.0.

  19. YEEEEESSSS!!! better than any camera announcement 🙂
    benefits: higher dynamic range, greater color depth, slightly sharper due to higher microcontrast (“pixel-sharpness”). No more compression artifacts such as posterization, block boundary artifacts (“macro-blocking”), counturing…
    It’s now also better to debayer, interpolate, sharpen and upscale.
    One big question remaining?
    What happens in Bulb? 14 bit A/D + 14bit lossless processing ?

  20. This is going to be a nice option to have but the best benefit of all will be not reading the parade of complaints from the SAR vocal minority about how 11+7 is the worst thing in the world.

    1. Agreed. I’ve never seen it in 50,000 images shot with various A7’s over the last couple years and I’ve never seen it in all the amazing Flickr images tagged with various A7’s, but if you listen to the chatter you can’t get a decent shot with the current compression.

      Now we’ll have to listen to people bitch about how large the files are and how slow the camera writes those huge files to the card. Not sure I’ll use this on my A7rII for anything outside of nighttime long exposures. Even then it’ll depend.

      1. When you aren’t even seeing artefacts on Flickr (as many images are low quality JPEGs)…. than you really don’t bother them 🙂

      1. it was a minority (Ming Thein and Lloyd Chambers whom started it even admit it affect a very specific and small portion of photography) but they were very loud.
        Sony changed it because it was bad PR that was blown out of proportion during the launch of the Alpha 7r mkII, probably in reaction the boat load of good review.

        1. Minority or not, I’ve shot the a7RII in studio along with the Canon 5DMIII and Nikon D750 and at times, certain images were unacceptable because of the cooked RAW files whereas the Canon and Nikon did just fine. I’m sorry, but you can’t sell a shot like that or even show your model at that. Giving professionals and enthusiasts an option is great no matter how you put it. Blown out of proportion, not if you make a living on selling your images. If you’re a weekend shooter, no big deal…

      2. It is certainly a minority. I believe they changed it more to the reviewers all mentioning it than due to complaints in SAR. Unfortunately bad press trumps consumer wishes.

        Either it’s great it happened and it’s great the complaints will cease (about this topic anyway).

        1. Consumer wishes? So, having an option to choose what type of RAW you want to shoot is a negative? The consumer shouldn’t have the ability to process their images the way they want to and the camera should? Doesn’t make sense to me. It’s not like it’s taking away what is already there, but adding an option for someone like me and others.

          What’s great about Sony is that they hear what the public wants and acts. Obviously, the a7RII is an amazing upgrade, but certain things need to worked out, but you could say this about any camera…

    1. This guy might have some psicological condition, autistic or depressive, this is not a normal healthy person behavior. Just like the Angry guy from Youtube.

  21. Fantastic news. I can’t wait to upgrade my A7R11. It would be nice if they also enabled my A7 to shoot 14-bit RAW, but I doubt its processor and buffer could handle it.

      1. Well then 🙂 I’m glad I held on to the a7RII. I hope this update clears up some of the hot pixels during long exposure as well. I couldn’t be happier.

  22. Also what’s going to be interesting is how much larger the file size will and will we really see an improvement and second how much slower will the FPS in continuous mode? I am 100% sure there will be something that we won’t like as it’s from Sony?
    Christopher

    1. Right now each pixel takes 8 bits. Worst case is they go from 8 to 14 bits/pixel, a 75% increase. It is also possible they could use11 bits/pixel, an increase of only 37.5%.

      The data transfer is the limiting factor, so if the file size is 1.75x bigger, the transfer time will be roughly 1.75x longer.

    1. Unlikely that the older cameras will ever get it. So far they have only committed to the A7Sii and the A7Rii. I expect they would also do the A7II. Possibly the rest of the A7 family.

  23. I have tried to register to the AlphaUniverse newsletter but it seems to be reserved exclusively to US residents. Why is Sony doing such discrimination ?

  24. The sole benefit will be I. Processing high contrast fine detail like shown in the example. DR will remain the same. If you have burger and dark area these will not change I.e. DxO tests will mostly be unaffected. I hope whining is vastly reduced

  25. With Canon putting out 50 mpx cameras now, a 120mpx APS-H in the near future 250 mpx sensors, will Sony wait to the A7rIII for a big upgrade? Who will compete with Canon?

        1. I find it troubling that the A7II isn’t being updated. The camera is not even a year old, and if they can add it to these other cameras they should be able to do it there. Features like minimum shutter speed in auto-iso made there way into the the A7RII and even the RX100IV… but no sign of them for the A7II. It’s a real shame, because while it may be the “budget” end of the full frame line up, this isn’t a cheap camera, and sony should respect that and give it some love.

          1. It is likely that uncompressed RAW will be added to A7ii. Sony’s press release said
            “… they have announced plans to add user selectable compressed or uncompressed 14-Bit RAW still image capture via firmware update to additional cameras beginning with the recently introduced α7R II full-frame mirrorless model.”

            A7Sii and A7Rii will be first, but there will be “additional cameras”, and A7ii is the next logical model in line.

  26. With all due respect (not) for those who take this issue seriously, but that image below the title seems like it has been brightened up by 5 stops at least, on order to show that artefact.
    I feel sorry for those geek that spend all that time researching and making a blog post about a “problem” like this. All that work, just to get few google ads points worth a big mac.

    1. I think you misunderstand the problem. The decision is mine, not the manufacturer.I decide what is the percentage of loss is acceptable to my work, not Sony.

      1. How do you decide about something that is beyond your abilities and power?
        The manufacturer will always have the the first word on how the image has to look like (every manufacturer cooks the files before delivery), you will have the last, but it will came always after what the manufacturer dictate.

        1. Perhaps beyond YOUR abilities, not of my abilities. And I just ask the obvious, Sony hands off of my image. My call.

  27. I bitched? I did not whine. I only asked for the right to have full 14 bit as any other company offers (in that prcie category).

    1. Presumably that’s one of the “additional cameras” they mention. At a guess, they’ll roll it out to the current gen first (a7sii shipping with it, a7rii and a7ii visa firmware updates) and older bodies will get it at a later stage (unless hardware limitations prevent it)
