Re: just got 7d, I am really frustrated right now.

I just recently bought a tamron lens and it is very slow at focusing compared to my canon lens. No matter how I set up the camera in the custom autofocus menu it is substantially slower at focusing than my canon lens. My percentage of in focus shots in bursts of shooting has dropped.

I don't think it is a calibration issue. I'm not sure of the theory as to why but if I want to shoot fast moving subjects I just use the canon lens. The tamron is a very decent lens and stationary subjects are no problem. Just the moving subjects.

I will probably stick with canon lenses even though they are expensive.
