Focus Hunting I have used this lens on a Rebel XTi and XSi and experience quite a bit of focus hunting when zoomed out at 70+. Anybody else seeing this? Any fixes?

I cleaned my contacts with a eraser like someone suggested and it worked for me.

This is a known problem for this lens. It's about a $100 fix from Canon.

I used this lens for one year until yesterday without any problems. Just yesterday I am experiencing the same issue: quite focus hunting when zoomed out at 70+ and when it stops it is not on focus! Any idea?
