ALL lenses behave this way, even the Canon L lenses and Nikon's professional lenses, and Minolta's G lenses. It's a characteristic. Even your eyes behave this way. That's why you see some people squint when they are trying to see clearly - squinting is like stopping-down your eyes.Originally posted by yeppie99

I can't explain the "why" part (maybe experts like Ian/Jed can) though.

I must point out that the issue is horribly complex and there are all sorts of views, even the major lens manufacturers aren't in agreeance over many aspects, so do you really want an answer?
