Sony Alpha 900 DSLR Digital Camera Review at Buy-n-Shoot.com
The A900 earns a Platinum award in this review, and Katrina Putker, the reviewer, writes:
While it is often easier to talk about the bad than good, overall the Sony A900 is undoubtedly a solid performer in the DSLR arena: it’s resolution is superb, it performs quickly and efficiently across the board (thanks in part to its dual BIONZ image processors), and at lower ISO speeds is capable of producing high quality images that are detailed, sharp and fairly accurately coloured.
Iliah Borg on the A900 vs Nikon D3X
Iliah Borg of libraw.org mentions briefly that he prefers the spectral properties of the sensor in the A900 over that of the Nikon D3X by a good margin, even though they share the same, basic sensor.
User opinion by Vern Dewit
Vern Dewit is a former Canon 5D owner and weighs in on this thread which asked for opinions on which full-frame camera to get: the Sony A900, Nikon D700 or Canon 5D Mark II.
In his reply, Vern says that the A900 is currently the best camera for landscapes, giving huge amounts of dynamic range and incredible shadow detail. He also shared a stunning photo of Mount Carthew and Buchannon Ridge in Waterton National Park, Canada in the post.

Vern further recommended the use of a Sigma 24mm f/1.8 (Sony mount) or Sony 50mm f/1.4 as a smallish lens that will cover landscape and indoor photography.
Hasselblad H3, Mamiya AFDIII, Sony Alpha 900 — A Comparative Test
This test was conducted by seasoned MF (medium format) professionals, who gave high marks to the Alpha A900 for excellent all-round image quality. I like the verbose summary by Tomasz Maciejewski, where he says:
Whenever the lights in the image burn out, Sony A900 clearly shows the details. Similar holds true in the shades. This is very important to the final processing of the reproduction. When one compares the pictures blown up to the same dimensions, the printout from Sony A900 is the most impressive. It has the best focus, it gives the greatest amount of “information” and is the clearest. Colors are natural without visible dominant colors.
