I'd be scared of the 200/1.8. Canon doesn't service them anymore, right? Does anybody? I'd hate to have that kind of money in a lens and have the AF break and be stuck with a dud.

I've never really looked at these lenses, but what you post about the two lenses is the feeling I've gotten from reading over at fredmiranda over the years. But Lighter + IS + modern would make me think about the new one.

Oh, and if you aren't using AF, you might look into a Leica R 180/2. I bet that's a mighty nice lens, and *might* be going for a bit cheaper than they used to since the R is a dead system.
