So my 30 D cant seem to lock focus in auto with my 50 1.4, 24-105 or 70-200 2.8.
All lenses work fine on my 5D.

Wow. I just posted the exact same problem on the exact same camera! Mine doesn't even attempt to autofocus. No hunting, nothing.
Let me know if you get it figured out.

I know on my 300d it was a spring on the secondary mirror, then inside something went wrong. I wish I could help you guys out more. Sorry!

Well mine was an easy fix. Basically I'm an idiot and forgot about Custom Function #4.

Does it lock focus in other modes? What is the AF mode set to?
