Re: Crop sensors are certainly obsolete

It's extremely relevant when you want a photo that has corner to corner sharpness which many of these so-called "full frame" lenses cannot produce despite the manufacturers applying their obviously loose standards to that part of the image area. Fortunately these lenses perform much better with so-called "crop" sensors and that's one reason why I use them.

Actually, they perform form worse to much worse on crop, corners included, with a very few exceptions, like some UWAs (but then you lose the UWA, so what's the point). The illusion of better performance is due to the fact that they are more uniform (in a mediocre way) across the frame, and to the lack of understanding how to compare formats.

They perform "better" than some EF-S lenses, with "better" meaning better corners,..., well at the expense of a worse center.
