A77 results on DXOmark: bodes well for NEX 7?
Sep 23, 2011

This is not supposed to be an accurate prediction but rather a 'what if' exercise [also given the widespread scepticism about DXOmark - this is just a mental exercise about one way of measuring sensors' performance].

What if the NEX7 improves on the A77's DXOmark (due to the loss of the translucent mirror) as much as the A580 improved on the A35's and A55's mark? If it does then the comparisons between the NEX 7's sensor and some other fabulous cameras could be quite favourable in every department except ISO (where it would not actually lose out as much as we'd thought):

Colour depth could go up to between 24.5 and 24.8 comfortable beating the Pentax K5 (23.7) and possibly even the Nikon D3X (24.7).

Dynamic range could go up to between 13.8 and 14.1 putting in the range of the best tested: the D7000 (13.9) and the K5 (14.1). [This would also trounce all full frame cameras tested]

ISO could go up to between 1106 and 1159 which would not give too much away to the D7000 (1167) and the K5. [Many full frame cameras beat these marks easily].

I'm definitely considering getting the NEX7 regardless of its DXOmark but considering that it might outcompete most, if not all, DSLRs at low ISOs (where tonality and dynamic range are concerned) and still not get too embarrassed by other APS-C sensors at high ISOs - I think Sony could be onto a winner!

Thoughts?
