i z tego co pisza w trybach ciaglych nie jest tak rozowo jakby sie ze specyfikacji wydawalo... zdarza sie sporo pudel... np

Continuous focus using Zone AF, nine points in the centre, AI Servo and the EF 200mm f/2L IS, tracking a running dog in fading light, the results were terrible. Over about 80 frames the camera got almost nothing usably in focus. If this result is representative of Zone AF, then Zone AF will be the way wrong choice for fast-moving subjects. We had better luck tracking the same dog with Spot AF.
