a review of the system-making camera, the Sony NEX-7. Noise levels are about a half-stop higher than the Nikon D7000 or Pentax K5, but considering the amount of detail, I think that it is a worthy trade-off.
The most interesting factoid to come out of it is a small but noticeable difference in overall image sharpness compared to the A77 and A65. The lenses used are the same, which means that the slight sharpness drop is attributable to the translucent mirror. It's not a lot, but the noise difference was already enough to make me hesitate buying an Alpha. Adding a sharpness issue almost seals the deal completely.
That said, the A77 is still very good, but the NEX-7 is amazing. It is sharp as all get-out, has amazing color, and the noise floor is low. Moreover, the excitement being generated by this, and Sony's immediate release of a world-class prime lens in the form of the 24mm Zeiss F/1.8, indicates strongly that this is destined to be a large, vibrant system. It is the only system into which I feel even remotely safe investing. I think that there is enormous potential signaled by this camera.
