Sony A900 Replacement – A950 Deal Breakers

Rumors are starting to abound of an A900 replacement coming in 2011 (I think) – named the mystic A950 with a new 30 megapixel+ sensor and either a SLT or traditional optical viewfinder design. I heard this from a guy who has a brother who has a friend who works at Sony R&D and he read this rumor on SonyAlphaRumors. Having shot the past year or so with my A900, I have an idea of what the A950 does and doesn’t need. I’ve used the A900 for various needs including weddings, studio portraits, documenting the painting process, grafitti shooting, Bratz dolls, Lego animation, etc. The A900 basically rocks, and only needs a few tweaks to be awesome. What are the deal breakers on the A900 replacement?

Live View


First off, live view is a deal-breaker on the A950. Deal Breaker is a word combination that I hate to write or read (I just felt some bile erupt in my innards at the sound in my head). People throw it around on forums everyday and when you look at the crap these people shoot it’s obvious that they only care about writing useless crap on the internet. But, live view is a deal-breaker on the A900 replacement. Why? Simply because live view dramatically increases the usefulness of a digital still camera.


As a stills device the A900 is awesome, but for shooting macro images or with manual focus lenses, the A900 sucks. Yes, it has a nice large viewfinder (for a DSLR), but the cheaper cameras like the NEX5 and every other DSLR now on the market have this very basic feature of previewing the image before it’s made in real time. Getting accurate focus and framing is just more precise on a large LCD than on a large DSLR focusing screen. It’s also nice for framing an image when you have the camera above your head or down low or at a weird angle. Live view is just a great feature if implemented correctly, and it’s a critical feature to have. Live view means precise macro focusing. It means precise focusing with manual lenses. It means the ability to enable remote camera operation from things like iPads, iPhones and computers (although I think Sony also needs to release a decent SDK for this to happen). Live view helps to frame images when your eye can’t be level with the viewfinder. Live view is needed on the A950 - period.


Take note however, Live View and Intelligent Preview should both be there. Intelligent preview is used to make a temporary image which is displayed on the LCD but not saved to the memory card. I love intelligent preview for quickly checking lighting and histograms in the studio. It’s needed because live view is useless for studio photography when external strobes are used. I use intelligent preview all the time in the studio to quickly preview the scene without taking a full image. And yes, it does make a difference, I don’t want to shoot a full-sized real image and have it saved to my memory card just to visualize lighting and to check the exposure histogram. Intelligent Preview is better for images made using strobes. Live view is needed for everything else.

HD Video


Look, yes, I know and appreciate the difference between stills and video. I bought a VG10 because it’s a proper video camera, not a stills camera that needs to be upgraded to a video device. Video is needed, but not in the same sense as live view, and no, putting the 24p 1080HD video option in an A950 will not kill the new CineAlta F3 or NXCAM cameras. The Canon 5D-II and other popular video DSLRs are being used to make movies because no other device is there to fill that niche, which is why Sony released the CineAlta F3 and the new NEX NXCAM. The F3 is for high-end Indy films and professional digital cinema. The NXCAM model is for Pro video, and there’s the VG10 for consumer video. People are not going to be buying the A950 instead of the new high-end video cameras to shoot movies with. People want to shoot video with video cameras, not giant DSLR rigs that look like baby transformers and have horrible moire performance. That’s why Panasonic is selling the AF100, why RED developed the Scarlet and Epic concepts, and why Sony released the VG10 (and will be releasing the Pro-NEX NXCAM). A video capable A900 would be an awesome compliment the my VG10. Video isn’t a deal-breaker in the A950, but it needs to be there.

Non-Crippled Exposure Mode


The A950 needs the ability to autoexpose in aperture or shutter speed priority modes when manual lenses are attached to the camera. With a manual focus lens you only have the option to shoot in full manual exposure mode with the A900. This sucks and is purely a firmware issue that should’ve been fixed years ago (and could be fixed by a new A900 firmware). I should be able to put a lens on the camera, adjust the aperture on the lens, and have the camera choose the shutter speed and ISO for a correct exposure, just like I can on my NEX-VG10. Without this basic function, your ability to use the camera is limited because you have to adjust the shutter to match the aperture you use. Even my old Minolta 7D chooses the correct shutter speed for an ideal exposure with a manual focus lens attached. It’s a very basic feature and should be a function on any camera body. One reason the NEX line is so popular is that people can use whatever lenses they want on their body (with adapters). This adds to the value of the camera, and it should be the same on the A900 replacement. Focus confirmation on manual focus lenses should also exist. Sure you might need to add an electrical interface to the lens, but this is possible with Canon and Nikon and their built-in rangefinder designs. It just makes the camera better. It’s useful when manual focusing with Sony/Zeiss autofocus lenses and as well old manual focus devices, it’s not a must, but would be awesome.

Optical vs. STL Viewfinder


If the STL viewfinder works as well as an optical one does and improves the user experience, then it should be there. Currently, the A33 and A55 do not do this. With the SLT cameras (and with the NEX-VG10) it’s very difficult to use the cameras in the studio with off-camera flashes. The reason is that the electronic viewfinders try to depict the scene according to the manual exposure the photographer sets on the camera, but this of course doesn’t account for the power output of the flashes that will go off when the shutter button is pushed. The resulting live view image is a black screen when I shoot in my studio with the VG10. This makes framing the shot very difficult and is also a rather huge deal-breaker because it severely limits the use of the camera on shoots. I like having an optical viewfinder because I can easily frame the shot (even if the camera isn’t turned on). What I’m hoping is that Sony will develop a dual-system hybrid view-finder, similar to the Fuji compact camera shown at Photokina 2010. Rumors suggest this will be available on the coming NEX7, and would actually make for a very nice addition to the A950 design.

In Summary


So, basically the A900 replacement needs: Live View, HD video and non-crippled manual exposure mode. If there’s a better viewfinder design than the current one that would be great, but it needs to be better than the A33/A55 design. A rangefinder should also be integrated to help manual focusing, but it’s not a deal-breaker.

A900 Firmware Update


Sony has released a firmware update for the A850/A900 which addresses the exposure issue with manual lenses. The update includes the following:


Faster autofocus, extended the range of exposure value (EV) compensation to increased to ±5EV, exposure bracketing range has been increased to a maximum of 6.0EV (-3EV, 0EV, +3EV). The A900 and A850 firmware updates are available on various Sony support websites, including http://support.sony-europe.com/dime/DSLR/dslr.aspx.

    And off course the new AF implementation. Even the A55 is now way faster then the Nikon D7000, so I would love such a thing in my A900 with more point, but more importantly evenly distributed focus points.

  2. LEdgars says:

    I would add some important features.
    For A950 is not only faster AF needed, but also appropriate AF 3D tracking. With current A900 AF continuous focusing is manly with central sensor. It feels worse than with compact camera.
    A950 needs fully functional dual card slot. Let it be CF and Sony pro duo memory stick combo, but with simultaneous writing of JEPEGs and RAWs, auto switch, when one card is full etc.
    Higher frame-rate (10fps) at least for APS part of frame.
    Continuous shooting and even bracketing with MLU (without mirror movement between frames).
    1/500s HSS with flashes.

    OK, so on this manual focus lenses issue: Does this mean that the Sony A900 with the most recent firmware update will function like my Sony A100? When I slap an A-Mount-to-MD adapter on my A100, I can use MD lenses (Manual Focus) in Aperture Priority mode. I am assuming someone can give me a little bit more insight on this issue. Is the A900 no longer crippled in its firmware? Thanks for some feedback! I need somewhere between three and thirty of these full-frame cameras and, therefore, I am being quite selective in my selection of body.

    Oh, by the way, this article is very well-written and hits the "big issues" in the A900. It's also has a great balance of personal commentary and strong organization. Good work!

  4. Mark says:

    Yes, on the manual focus lens issue the most recent firmware will allow Aperture Priority exposure mode.

  5. ATG says:

    Well said & written.

    Let's not forget: Tethered Shooting.
    Sony has only 3 cameras that can shoot tethered.

    If tethered works on your camera, then ATG AK1 Un-Tethered Systems works by shooting wirelessly (un-tethered)

  6. Gyne says:

    which is better the canon or the sony? some professionals i have known they preferred canon? hmmp? makes me wonder all the time.

  7. nhia vang says:

    The only thing sony needs to do is deal with the ISO issue. but other than that it's a great system and i like for sony to keep it's full frame lineup. the A850 is a great DSLR I love it and dont care much for live view or movie mode. just want a DSLR that can shoot stills to the best that it can and in any mode so for me is just the noise/iso.

  8. Tyng Tan says:

    Yeah I think it looks good, but I think that there are elements of the design would be a pain and would not work ergonomically.

  9. Mark says:

    So it's more than a year after this article was written, camera stores have pretty much given up selling the A900 and Sony have yet to release an A950

    To call your performance "pathetic", Sony, would be a complement.

    WAY past time to switch to Canon and that is exactly what I am going to do.

    No. a950 will be presented at photokina germany, 54MP…
