Sony Alpha DSLR-A900 (Body Only) review: Sony Alpha DSLR-A900 (Body Only)

A camera in this price range doesn't really need to have great burst performance, but I do expect it to have fast autofocus and single-shot speed. Unfortunately, the A900 doesn't always meet expectations in this respect. For instance, its shot lag under optimal conditions tends to be inconsistent, ranging from as fast as 0.3 second to as high as 0.5 second--the former is quite good, the latter just OK. Shot-to-shot runs about 0.5 second. But my biggest gripe is with the relatively slow autofocus (at least with the 24-70mm f2.8 lens provided by Sony) in dimmer conditions, like indoor lighting. It's slow enough that I missed several shots of active kittens, and tests out at about 1.2 seconds to focus and shoot; that's about the same as a sub-$1,000 dSLR. The Nikon D90 feels more responsive. On the upside, DRO doesn't seem to slow shooting at all.

Photo samples from the Sony Alpha DSLR-A900

Technically, I think the A900 produces excellent photos: it has good noise numbers across the range, low color variation, and so on, all of which manifest in the photos. However, after hundreds of photos, I still haven't experienced that "wow" moment I expect from a camera in its class. While it has the capability to produce sharp photos, usually they're not as sharp as I'd like. The high resolution lets you get away with a lack of sharpness, to a certain extent, since you don't have to crop in as far to get the same size print. Photos get noisy and a bit mushy starting at ISO 1,600; I think the Canon 5D Mark II's look better. The color is very good, bright and saturated or subtle when necessary. I have gotten some odd red-to-orange shifts using automatic white balance indoors.

The Alpha DSLR-A900 isn't bad for a first full-frame effort, but Sony has some catching up to do with Nikon and Canon, both of which have had far longer to refine their products in this class. (Though Sony's lack of a huge commitment to optical image stabilization works in its favor here.) I really tried, but I just couldn't feel the love.
