Photo.net Review Excerpt

Earlier this year Sony said they were working on a 24MP full frame DSLR with built-in image stabilization and they intended to bring it to market by the end of 2008. Well, they did! The Sony Alpha A900 is just that camera, and what’s equally noteworthy is that the price is “only” $3000. When you consider that the only other current high pixel count full frame DSLR is the $8000 Canon EOS 1Ds MkIII, the $3000 price tag seems almost cheap. Nikon’s new full frame DSLR, the D700, is also $3000, but it has a 12MP sensor and Canon’s venerable EOS 5D full frame DSLR (which also has a 12MP sensor) currently sells for around $2200. The Sony Alpha A900 certainly sets a new price/specification standard, at least on paper.

If a 24MP full frame DLSR for $3000 wasn’t enough, Sony added in-body stabilization via sensor shift technology. The specifications indicate higher performance than the system found on their crop sensor DSLRs and they say that it should offer up to 4 stops of stabilization. The obvious advantage of in-body stabilization is that you only pay for it once, and every lens mounted on the camera becomes part of a stabilized system. That means that all wide and normal primes become stabilized, something currently not possible with Canon and Nikon’s approach of putting stabilization in the lens rather than the camera body.

The Alpha A900 uses dual image processors to deal with the large amount of data, which the sensor generates and enable a continuous shooting rate of 5 frames/sec. The ISO range is 200-3200, expandable to 100-6400 via a custom function. While not as wide a range as the Nikon D700 (100-25,600), it’s probably as much as most photographers will need.

It is now mid 2012, I have used a pair of Sony A900s since they were available to professionally photograph weddings and portraits. They have been my work horse cameras now for over 3 years. Zero issues, excellent images with the best out of camera color of any 35mm DSLR I've used.


I say this in case someone is ever interested in a used A900 ... but not mine! I'm keeping them : -)

Could we please get an actual review of the A900 instead of a press release?

Richard Harris , March 15, 2009; 03:57 P.M.

Richard, that is my experience with my Sony A100 - but that is a lower class body. I'd hope that with higher end products they will be much more realiable. Afterall, Sony have been making pro quality video equipment for years and have earnt a reputation there for a reason. I think it's safe to say a body of this calibre is high quality, you've just been unfortunate with your previous experiences I feel (no doubt you aren't the only one with these such experiences though!)

Richard McGee , February 24, 2009; 11:18 A.M.

I hate to say this, but... I'm a gadget junkie, have owned a good deal of Sony products, including cameras, and I have had to tell myself over and over that no matter how good it looks on paper, Sony products will usually always crap out on me first. The company has a reputation that they don't deserve.

Instead of using many technical words of description - may be a few example photos show best the result of the Sony A900. One of the first projects I did was lotus flower wallpapers, then Jungle wallpaper and a series of travel photos Cambodia.

Since I do mostly nature photography, I appreciate Sony's potential to work in extreme light conditions and still display beautiful brilliant colors.

The A900 definitely is an improvement compared to the A700 I used extensively before. One of the most difficult tasks for me with any previous ( Sony ) camera always was to shoot white flowers, white roses, White lotus with A900 , etc. The A900 is the first one to have a clean white color rendering with all smallest details in contrast still visible.

John, go to dyxum.com and look through the lens database. You can search by brand - it will give you a good idea of the options available.

Just bought the a900 and so far I don't really miss the pop up flash. I've been able to do some sample shots with about half of my old Minolta "A" lenses along with a Tokina APO 70-200 f2.8 and the results so far have been great. I'm glad to have caught the warning about Raw on a Mac, thanks. I also have the K/M D7 and the Sony a700 but when the 900 was available in Portland, Oregon I just had to have it. As I do some work with it I come back with some more comments. Bob Moon

I would like to know what are all the lenses available for this Alpha-900 from Minolta, Sony, Zeiss, and Sigma. I'd appreciate it if someone will fill me in on these information

Pan Lao , September 26, 2008; 09:23 A.M.

Good review, love intelligent preview. For my hope more raw converters support soon, raw images here sony a900 preview off gallery for peoples who want.

Jose Amado , September 19, 2008; 04:29 A.M.

I do like Sony TV's. But now there's also the Canon 5D MKII. Maybe I'll wait for a Alpha A900 MKII...

Richard Harris , September 15, 2008; 09:01 A.M.

To add to that Peter, at the moment you can't trigger wirelessly w/o a big 56AM or 58AM flash on top... that's pretty expensive too! So we can surely await a wireless transmitter sooner rather than later. While I do like the wireless flash via pop up, I can also admit the advantages of a more controlled lighting w/o any pop up flash input (in some situations). But, if you ask most Alpha photog's, we're all going to say we want a pop up flash rather than NON at all.

Looks a great camera. Can't wait for the next :P

Peter Blaise , September 15, 2008; 06:18 A.M.

Too bad about the lack of in-built on-camera flash for wireless control of remote flashes, something I'd come to expect on even the cheapest Alpha SLR cameras, and, of course, was also on the top of the line Alpha camera, too, the Minolta Alpha/Dynax/Maxxum 9 SLR film camera. I can't see having to pay for and lug around and power a big intimidating separate accessory flash unit just to allow the A900 to do what my little Alpha cameras have always done so well on their own.

Otherwise, the detail available in captured images promises to be incredible, and the viewfinder seems equal to or better than the incredible viewfinder on the film Minolta Alpha 9, which, if I recall, was like not having a camera in front of my face at all, the scene was so big and bright, like looking directly at my subject without a camera at all.

Well, two out of three ain't bad - captured detail and perfect viewfinder.

Now to wait for a subsequent full frame Alpha with Minolta's traditional splendid intelligent in-built flash.

WOW!!! I Really don't think Nikon OR Canon can compete with the price point and statistics like this. They ( Nikon & Canon ) are going to have to rethink their pricing . I sure am glad I've stuck with Minolta/Sony for the long hall. I think this is what we have all been waiting for ( some real competition ) in the DSLR market.
