So as I understand it, diffraction is related to your aperture regardless of the format of your sensor/film. So if you shoot at f/22 with a medium format camera or an APS-C you will experience diffraction with both, thus reducing resolving power.

But wouldn’t this mean that if I wanted to shoot a landscape it would be better to use a MFT camera at f/11 rather than a FF one at f/22 or a medium format one at a (hypothetical) f/44? wouldn’t the diffraction from the FF and MF camera basically negate their advantage in resolution?
