I have heard and seen how the newer cameras (With its obscene Megapixels) are pushing the boundaries of what some lens old and new can do in terms of sharpness.
My question for debate is can a newer lens that is supposedly sharper than any old lens push the boundary of your old camera that it makes that camera buckle.
So far i have only come across examples that oh this lens is super on a FF D700 but the 12 megapixels a limiting factor. and if you want detail upgrade to a say d800. or anything with higher pixels.
Assuming certain factors to be a constant,if crop camera is used then compare with a crop camera, pictures taken with a tripod, best aperture,shutter combination for the shot, no in camera adjustments for saturation etc used.. Three types of scene, macro, potrait, landscape. would a FF camera with 12 to 16megapixels be any different than another FF camera with 24 to 36megapixels. Or it is just the convenience and technology improvements that rule and mega pixels are hogwash beyond 16megapixels.
