Let no diffraction limit your creativity, Larry.

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).

They do have some interesting stuff in there, that I'll definitely
need to go and re-read, such as how the anti-aliasing filter affects
all of this. Although I'm beginning to suspect that as resolution
increases, diffraction and lens issues will soon render anti-aliasing
as unneeded. If we're sampling at twice the diffraction limit, or
the lenses resolution, do we really need an AA filter?
If I had more skill with a spreadsheet, it would be interesting to
graph out diffraction limit vs resolution on different sensor sizes.
It would also be interesting to see where various lenses fall in
sharpness. I.e. on my K-5 with my FA77, when does the lens, the
sensor or diffraction limit resolution?
The more I learn about photography, and what is required to maximize
the technical quality of my photos, the more tempted I am to just
quit worrying about how sharp they are, and just have fun taking
snapshots.
