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.

With its 5.62x crop factor (compared to 135 format), f5.6 translates into f5.6 x 5.6 = f31 on FF. So yes, well into very high diffraction softening. So you are dealing with the same softness for the image some landscape and macro shooters deal with who use f32.

f4 will translate in f22 for FF.



You are right in that you can perk it up to make them passable for non-serious stuff, I agree.
