Maybe its the lens?

I get the 'jitter' problem with my Bigma on EVERY camera I used it at the low end. 50 to 100 mms. Often it has to do with 'One Shot' or 'AI Focus' and especially 'AI Servo' settings and the focal length. My 7D and Bigma on AI Servo goes nuts trying to focus at the low end - constant refocus sometimes. I then shut off AF (using the lens switch) and go manual focus with long lenses then to not miss the shot. My 2 cents.

Ubilam.
