I can see the real diffraction limits at f4 on the Q. I really need 2.8 or lower before it's hard to see. On Mon, Jul 2, 2012 at 9:10 AM, Mark Roberts postmas...@robertstech.com wrote: Larry Colen wrote: Although I'm beginning to suspect that as resolution increases, diffraction and lens

A few nights ago a friend stopped by with his Nikon D800. He mentioned an interesting point, that his camera is diffraction limited at f/4. And so, it turns out, is a Pentax K-5 (I'm using their data for a D7000 to find the diffraction limit).

What settings did you put in for your calculations. I tried a bunch of combinations, and didn't get diffraction limiting at f/4. f/8 and up yeah, but not that low. On Sun, Jul 1, 2012 at 5:48 PM, Larry Colen l...@red4est.com wrote: A few nights ago a friend stopped by with his Nikon D800. He
