Interesting technical guide. A lot of it applies to photography using any advanced DSLR. Good to read.

This statement I don't understand:

The effects of diffraction are partly influenced
by the size of the pixels in the camera image sensor...

I suspect this is nothing more than an observation that 100% viewing of a 36 MP image (fixed FX area therefore smaller pixels) is a higher magnification than with lower MP cameras and therefore blur from any source, diffraction or other, will be more noticeable.

It is good that it says the effects of diffraction because certainly diffraction is a function of the lens configuration and not other components in the camera (sensor, film, or other included).
