Re: How to see diffraction in photos

Yes!  That is exactly what you would expect from diffraction.

As the aperture gets smaller (higher f stop numbers) diffraction gets greater.

If you were shooting with a 42.5mm lens at f/22, then the aperture is 2mm wide.

if you were shooting with a 15mm lens at f/16, then the aperture is <1mm wide.

If you shoot with the 9mm lens at f/16 then the aperture is 9/16th of a mm wide.  About half a mm: that is a very small opening.
