Hello everyone,
A question on diffraction: frequently diffraction effect seem to be mentioned with reference to f-numbers, however, if I am not mistaken, diffraction effect negatively correlate with the diameter of the lens aperture and not with the f-number itself. As a result, everything else remaining equal, the effect should be the same at 150 mm f/11 and 300mm f/22.
Just trying to get it clear for myself so any info/reflections are appreciated!
Cheers!
