next PZ lens test report: Pentax-03 Fisheye 3.2mm f/5.6

Where's the diffraction softening zone on this system again? I assume f/5.6 is way into it?



Regardless of that, I did quickly play with some sharpening and noise reduction on the samples, and they can perk up a lot with a little more processing. Certainly well into the "good enough" category.

According to my calculations, it is F/5 (F/4.9 to be exact). Which means that for optimimum results the lens shouldn't be stopped down further than F/4.



Kind regards, Wim
