Fujifilm GFX100/GFX100S: Diffraction Effects from f/5.6 through f/32

This page shows diffraction dulling effects from f/5.6 through f/32 on the Fujifilm GFX100S/GFX100, which have ~3.76 micron pixels, same size as the Sony A7R IV and the PhaseOne IQ4 150.

Recommendations are given for handling the competing goals of increasing depth of field vs diffraction dulling.

Discussion also applies to the 50-megapixel Fujifilm GFX50S. While the GFX50S is in theory better on fine details by 1 stop, diffraction dulling still affects overall contrast the same, dulling the image as a whole.
