There's a very interesting comparison of lenses (Sony, Sigma, Zeiss ZA, and even a Summilux) by Roger Cicala over at lensrentals:
LensRentals.com - NEX-7 Lens Imatest Resolution Comparison
I was particularly shocked to see the Imatest numbers for the Zeiss ZA 24/1.8, which I have and like very much: 475 wide-open at f/1.8, but increasing to 960 when stopped down to just f/2.8. I guess I've been so grateful to finally have a fast lens for a compact camera I hadn't quite grasped how much better it is when stopped down a bit.
