The Canon FD Macro 50 mm f/3.5 (I've got the SSC version) seems to corrected for close-up images, the optical design dating back to the beginning of the 1970s. ... BTW, near infinity, the Canon behaves in a very similar way to its Minolta cousin : if you're looking for sharp corners, you better use f/11.

Today I checked the Canon nFD 3.5/50mm plus a few other "normal macros" at infinity, among them also the Minolta MD-III 3.5/50mm. While wide open, it has similar corner issues as the Canon nFD 3.5/50mm, but is is much better than the Canon when stopped down to f8: Perfectly sharp corners (FF, 24MP) and no CAs at all. The Canon hardly improves when going from f4.5 to f8 (always talking about infinity performance; close range is a different story).
