OT: Lenses: I swear they make this stuff to break

[Racer X]

I have about 5 Nikon MF 50mm lenses at work. I can tell which are older just by looking at the build quality, the feel of the focusing ring, the crispness of the clicks of the aperature ring, that sort of stuff.

My Canon EOS USM lenses feel pretty flimsy, but they function fine. But they feel like children's toys compared to my older Canon FD MF lenses.
