Alpha A900


The Sony A900 is the company's powerful attempt to compete with the big boys with a full-frame $2999, 24.6-megapixel resolution SLR. There are some features notably absent, though, and our lab testing turned up problems with color accuracy and image...

The 24.6-megapixel Sony A900 is a high-res, high-performance and high-priced camera, selling for $2999 for the body alone. There are several impressive specs, including maximum 5 frame per second burst shooting at full resolution and an excellent...

Sony Alpha DSLR-A900 (body only)


Sony makes a point of not calling this a "professional" camera, instead referring to it as the "flagship" model of its dSLR line. However, it's priced like a pro model, and its full-frame competitors--the Nikon D700 and the Canon EOS 5D Mark II--are...

High resolution; in-body image stabilization; nice viewfinder; great accessory system

Can't lock focus-point selector; Intelligent Preview button much too easy to hit accidentally; some subpar aspects of performance; no Live View; loud mirror

A good first try at a pro-level camera, the Sony Alpha DSLR-A900 has the high resolution but unfortunately lacks some of the performance and usability you expect from a model in its price range.

Sony Alpha A900


The Sony Alpha DSLR-A900 is a powerful digital SLR camera aimed squarely at professionals and enthusiasts who covet a full-frame sensor--and who can afford the investment. This camera costs $3000 for the body only, and $5250 with a 24mm-to-70mm f/2.8...

Easy to use, accurate, and solid ; In-camera stabilization really works

Noise reduction softens images ; A bit pricey for new Sony buyers

A high-quality, respectable member of its class, but noise handled poorly above ISO 800

Sony alpha DSLR-A900


D-SLRs are definitely where the action is in digital photography. Sales of compact point-and-shoots may have hit a wall in this recession, but digital single-lens reflex cameras continue to do well as prices have come down and quality has gone up. The...

Beautiful 24.6MP stills; outstanding viewfinder; Intelligent Preview works great; easy to use

Expensive - for serious photographers only; limited "cheat" modes; heavy and bulky

If you want pure picture prowess, definitely consider the alpha A900.

Sony Alpha DSLR-A900


In the cut-throat digital camera market it's increasingly unusual for products to be shown in prototype form or announced more than a matter of weeks before they hit the stores. There's several reasons for the manufacturers' habit of playing their...

Class-leading resolutionv (as long as your lenses are good enough) ; incredibly solid build quality, environmental sealing ; Intuitive operation and uncluttered control and menu system ; Excellent out of camera JPEG results with superb tonality,...

Noise reduction settings applied to raw as well as JPEG files - cannot be 'turned off for raw but left on for JPEGs' (as is normal practice) ; Relatively high levels of noise at anything over ISO 400 (ISO 6400 is of very, very limited use) ;...

The Alpha 900 represents in a nutshell the almost schizophrenic nature of Sony's digital camera division, which can market compact cameras with smile detection and a Playstation style user interface at the same time as this, perhaps the most...

Sony A900 SLR Digital Camera First Impressions Review


The Sony Alpha 900 is Sony's new full-frame, flagship SLR. It shoots 24.6 megapixel (6048 x 4032) shots at a maximum burst rate of five images per second. This impressive feat is courtesy of the new design for the shutter, and the dual BIONZ...

- Full frame for a reasonable price - Solid, weather resistant construction - Well laid out controls and settings - Unique buttons for most common settings

- Heavy (2 lbs before battery and lens) - Still costs $3000

The Sony Alpha 900 offers a full frame SLR at a reasonable price. In the short time we got to use it, it appeared sturdy, well designed, with clearly labeled buttons and a logical menu structure. It also fits well into the hand and is comfortable to...

Upstart Sony DSLR Pops Nikon and Canon on the Chin


Sony came out swinging for the fences with the introduction of its flagship DSLR, the A900. Billed as a prosumer digi-snapper, but packed with a panoply of

Bright, vivid and spacious viewfinder. Excellent in-camera image stabilization system. Easy no-menu adjustments with Fn button and multi-selector toggle. Killer price for the highest resolution, high functioning, easy to use DSLR

Focus points not big and bright enough in brightly lit situations. No latch for memory card cover. Pointless postage stamp sized LCD on top of the body. No continuous ISO in viewfinder. Power switch on left side of body

Sony A900 Full-Frame: Hands-On Preview


At 24.6MP it's the highest-res DSLR, and the A900 is the first full-frame with body-integrated IS (image stabilization). Does the Sony A900 flagship deliver performance as promised?

Sony A900 Review


Upon taking the Sony A900 in your hands for the first time, you immediately notice how well built it is, and how the large, carefully sculpted grip fits your hand like a glove. Weighing in at just under 930 grams with a battery and 850 grams without...

Does this mean that the A900 is the perfect camera then? Of course not there is no such thing as a perfect camera. The auto-focus system, while capable, leaves a lot to be desired. The AF points need to be arranged more sensibly, and all of them need...

Sony Alpha DSLR-A900 Digital Camera - Full Review - The Imaging Resource!


The Sony A900 has to rank among the most anticipated digital SLRs in recent memory. The company first showed an early version of its upcoming flagship design at the Photo Marketing Association tradeshow in the spring of 2007, and at the following...

Extraordinary resolution, nothing touches it at its price point ; Built-in SteadyShot image stabilization ; Surprisingly fast, given the amount of data the camera is pushing around ; Good color rendering: Natural without seeming flat ; A lot of nice...

Some image noise even at ISO 200 ; At anything above ISO 200, noise limits maximum print size before resolution becomes an issue ; High-ISO performance doesn't match that of Canon EOS-1Ds Mark III (Which is also 2.6x as expensive though) ; Dynamic...

The sensor is mounted on a moving platter that allows for in-camera image stabilization, branded as SteadyShot Inside. That's another world's first for a full-frame digital SLR, and it's no mean feat when you consider that the sensor shift mechanism...
