Hi Lenny. Are you saying that you don't have any noticeable degradation due to diffraction between f/22 and f/45?
I'm just wondering. I am not saying I do see any...I don't shoot past f/32 on 4x5 usually, but usually always at f/22 or wider. I seem to notice a little more detail in scans at the wider apertures of f/16, f/11, etc., but that never translates to my darkroom prints.
