Why is there a design diffenrence? Isn't the CCD flat or is it "sfaeric" or

Please explain!

No problem. Picture a lens projecting light on to a 24x36 rectangle. Now picture a small postage stamp in the center of the 24x36 rectangle. Light passing through the center of the lens still covers the postage stamp, but light from the outer edges of the lens are now far outside the imaging area represented by the small postage stamp. Viola! The lens with the sharp center and the mushy corners suddenly appears to have changed its ways, becoming sharp all the way around (at least, until it is put back on a camera that records a 24x36 image.
