Well, I must say I'm a bit confused, that's absolutely correct... To be more precise let me explain the cases which I have in mind:



1) Two 1,5x cropped sensors with different pixel densities (e.g. 12mp vs. 18mp). Two images are shot at F13 (same lens) and they are printed on a 60x90 paper. Compare the effects of diffraction on both prints.



2) One 1,5x cropped sensor, one FF sensor with the same pixel sizes. Two images are shot at F13 (different DoF, same lens, different subject distance to provide the same FoV). Print on 60x90 and check the effects of diffraction.



3) One 1,5x cropped sensor, one FF sensor (same sensor resolution, FF has bigger pixels). Two images are shot at F13. Same DoF, same lens, different subject distance to provide the same FoV. Print on 60x90 and check the effects of diffraction.



4) One 1,5x cropped sensor, one FF sensor (same sensor resolution, FF has bigger pixels). Two images are shot at F12 (1,5x) and F18 (FF). Same DoF, same lens, different subject distance to provide the same FoV. Print on 60x90 and check the effects of diffraction.



Kind regards,
