There have been comments in various forums about the NEX 16/2.8 performing better on the NEX-C3 than it does on the NEX-5 and NEX-3. Supposedly the C3 has improved microlenses to better deal with off-axis incident light. Such a refinement would be expected to help with color and sharpness in the edges/corner of the frame with non-telecentric lenses. Pretty much any small wide angle lens and even some of the smaller normal lenses ought to benefit. I just came across a terrific demonstration of this in the Xitek forums: http://forum.xitek.com/showthread.php?threadid=902861 The NEX-7 is expected to offer: 24MP sensor with improved microlenses to handle off-axis light Class leading EVF Peaking functionality Sounds like a heck of a camera for adapted legacy lenses. The only thing missing would be in-camera stabilization.
