Re: Diffraction limiting

"I always mistakenly thought diffraction limiting was kind of similar for lenses at a certain sensor size. this suggests not."

Actually it is pixel density plus sensor size. Within that it is determined solely by the aperture as in f-number. Lens makes no difference.

Within the normal aperture range you can ignore diffraction, it produces a very slight softness that yields to unsharp mask easily, though it does mean you shouldn't stop down beyond mid aperture unless you need the depth of field.

The real lesson here is that anyone can put poor advice on the internet with no editorial process, I know I do.
