Conclusion
Among today’s new APS-G generation, the K5 is certainly a solid choice, along with the D7000 and the A580, although the Sony Alpha model does not have such an impressive dynamic range compared to the other two at low ISO speeds. All three sensors have solid color depth and good low-light behavior, too. Choosing one among them will certainly be influenced by considerations other than the pure image quality, which for all three of them is very good.
The a55, however, is different. The translucent mirror used in that body is an improvement if you intend to use your camera to record a lot of videos. But it is a slight handicap if you intend to shoot high-quality photos. Sony clearly made a choice —improving the video functions — that has a noticeable impact on still photo quality. But even with still photos, image quality should be very close to a Nikon D90, which is a pretty good performance.
As for the EOS 60D, its sensor ranks last for all metrics. Its biggest problem is, of course, its high ISO performance, which is inferior to that of the a55, even though the Canon uses a standard mirror technology.

The Nikon D5100 replaces the D5000 in Nikon’s lineup; it finds its place right below the Nikon D7000, according to Nikon’s marketing the D90 is still positioned between the D5100 and the D7000, however the spec sheet and the performances of the D5100 make this hard to believe. This is because the D5100 shares the same Sony 16 megapixels sensor as the D7000. The major difference between the two bodies being the AF: 11 points with 3D tracking for the D5100 (presumably the “old” MultiCam 1000 already used on the D90) versus the 39 points with 3D tracking now used on the D7000. |
