I know. I tried with my old Panasonic Lumix super compact and..well.. it was a disaster. With this 7D however things are a different matter, even with the kit lens. And when I made my shots I wasn't allowed to use a flash and it still worked out great.
Can't wait for 1st week of April when my 70-200mm f/2.8L IS USM II arrives. That should make it even better.
