Lost all credibility with me on the diffraction howler.


Yes, that one is a doozy. As you might know, diffraction is proportional to pixel size, not the sensor size.

Olympus M1.3: 3.36 microns

Sony a7rIV: 3.76 microns

Nikon Z 6: 5.92 microns

Diffraction is an optical property. It has noting to do with pixel size. Sensor size determines the size of the blur produced by diffraction on a print of given size.


Diffraction is an optical effect.

The 2D diffraction pattern is called an airy disk. When the size of the airy disk central peak becomes large relative to the pixel size, it begins to have a visual impact on the image.
