So I've been told. I do know that at f/11 there is some degradation but in my view it is slight. I think the original poster needs help, avoiding ISO 3200 and f/22. Backing up from f/22 to f/11 will help and it should be noticeable. Going from f/11 to f/8 or f/5.6 I agree will help a little more, but I'll bet it would be very hard to notice.

I think if I convinced him to shoot at ISO 800 f/4 or ISO 400 f/4 he'll be much happier. Whether f/5.6 is sharper than f/8 and f/11 wasn't his main issue (but I do agree, it's true to some degree).

Yep, just making it clear that the "F/11" rule doesn't apply as is and diffraction doesn't 'start making you lose resolution at F/11' as the post stated. It starts much sooner than that.

The general rule for micro four thirds cameras would be an "F/5.6" rule, so that's what should be mentioned to avoid confusing the OP.
