Just to demonstrate two extremes of focal length, I performed a test with the 24mm PC-E lens and the 500mm f/4 G. You can see in both cases, there is a small difference between f/8 and f/11. f11 to f16 a bit bigger, then f/16 to f/22 a large step. The 500mm doesn't go to f/32, so couldn't test that.

So, it looks like the practice matches the theory again.

24mm PC-E (100%):

500mm f/4G (100%):

We are talking about diffraction here. What camera did you shoot these pictures with? I think you have forgotten to mention it.

Decision, decision, we are the slaves of decisions we made inadvertently.

May God forgive us our imperfections!

Dust to dust, what on earth are we entitled to claim?
