Was just clarifying, to anyone else who might be reading. If f/22 and 1/100 isn't desirable, then simply open the aperture by a few stops, and speed up the shutter correspondingly. One can still use the Sunny 16 rule (or Beach-22 rule? did I just make that up) as a starting point
, but adjusting it so that you get the same exposure without running into the problems caused by a very tiny aperture.
Sunny-16 rule still gets you to f/5.6 and 1/800, or beach-22 gets you to f/5.6 and 1/1600... voila, proper exposure and no tiny-aperture diffraction issues.
Yeah to all you've said, I'd just include the diffraction concerns in any statement that infers f/16 or narrower, especially for a crop body!
A lot of things get passed down from the film days, including MF days, that need to be "reworded" for DSLRs..."Understanding Exposure" is now in its Third Edition, simply because the first two didn't keep up with the Digital Revolution! I haven't read the Third. My copy of the Second is still certainly useful, but without places like POTN you are left with "gaps"!
