I've decided to give up on auto-focus. Score +2 points for anyone that thought "Bet he shoots with a Canon digital!"
I'm serious though. Today a whole panorama series was ruined due to autofocus "inaccuracies" with my camera and lenses.
For those that say "send it in to Canon" I already have. It seems like when they tune it for one lens it gets un-tuned for other lenses.
I have a few lenses that it does okay with but then there's a couple that it just always wants to back focus with. You guys have heard of these issues from others before so I won't bore you with the details. Let me just say that I know what I'm doing and it's the bloody camera/lens fault. It's a good thing I don't do much action otherwise I'd be pretty ticked off.
Now, once I move to Illinois I'm going to hand walk all my crap into the service center and ask what they can do to make all the lenses autofocus correctly with my camera. But until then, it's manual focus for me 100%.
Yes, I'm trying not to be so frustrated but I am.
