It seems that at times folks are getting focused images of a moving target in the first few frames, and then back focusing onto "other objects".
The problem I am seeing, and I can replicate it now, is that the first frame is always sharp out of a burst of say 7. Frames 2 to 6 are a mixture of sharp, unfocussed, or focus placement error, the latter being very much my fault but it is easy to see, for example the engine cowling of a race is in focus instead of the drivers head, the AF point viewing confirms this. What I am unhappy about is simply the number of unfocussed shots, not front or back focussed, just nothing in the shot is in focus. This is always in AI Servo and High Speed drive mode (10fps). Single shot drive and AI Servo gives great results, but I can't use the camera in this way for the motorsport photography I do.
I would be very very curious to see what results people get using either low speed drive mode (3 to 5 fps) and reducing the speed of high speed drive mode to say 8fps, all while using AI Servo.
I also agree with the sentiment, that if the camera is working so hard to buffer and write the images generated at 10fps to the card, so much so that focussing operations are interupted, this is indeed a major major problem.
