No it doesn’t. Diffraction is a function of aperture and magnification only, not mp numbers. If you look at a high mp image at a higher magnification (which it seems most people do) then it appears that diffraction is more apparent, but that is simply because you are looking at it bigger.I wonder why Canon can't just give us two or three sensor options? Maybe 20, 30 and 60 megapixels. Then everybody would be pleased. Would threy really have to change a lot of the internals ofd a camera, if the megapixel count changes? If the camera can process 60 megapixel images, it should also be able to handle 20 megapixel images. At the moment I am working on hundredsof old photos I took with an 8.2 megapixel APS-H camera and I love how crisp they look on a pixel level. With a high megapixel count diffraction sets in much sooner. Of course you can always downsample those photos, but then you would still have to handle those large RAW files.
