Hi Ioan, the color depths quoted here are test results conducted by DXOMark

Hey. I know that Sony A-77, A-65, and NEX-7 have the same sensor. In this case, down't they have the same color depth (24 bit like A-77)? I'm asking because I haven't seen this specified on A-65 and NEX-7, presentation page.

A77, for me is clearly the better camera, bringing breakthriugh technology.
