Hi, I'am italian Cps pro, I bought a 7d just to have a second fast camera body with my 1d MK3 but last week, shooting a rugby match (with the 400 f2.8 is usm lens), I've had big problems with the Af tracking. My camera doesn't follow the target expecially in low light as using the single af point as the af point expansion. Please, somebody may tell me if Have the same problem? Excuse me fo my bad english!!
Regards.
