I'm having no luck getting my paws on a decent Canon FD wide angle (already have the 28mm f2.8, would really like to go 24mm or wider), so I'm widening my horizons to third-party manufacturers...

I have the EFS Tokina 11-16mm for my digital camera (30D) and am beyond pleased with this lens. I've read a lot of good things about the older ('80s, mostly is what I'm looking at) Tokina AT-X line...do any of you guys have any experience with that gear? Should I go for it? Stay away? I have my eye on a Tokina AT-X 28-85mm...I know it's not wider, but it may be more versatile, while still providing the same wide end.

Anyways...any sort of feedback on the older AT-X line would be much appreciated.
