Is anyone else having problems getting sharp images with the 7D when shooting action. I've had the camera approximately 6 months and the results I am getting are appalling. Every image is soft! I've been shooting top class rugby and football for 15 years and this is by far the worst camera I've owned. It's not a lens issue as I use a 70-200mm 2.8 IS Canon. In the past I've owned 10D, 20D etc... and the image results from these cameras are far superior! Looking into this problem on the net it seems the 7D has had AF issues anyone else experiencing problems?
