Hey everyone. I'm having some difficulties with my 5D3 in AI servo mode and I am wondering of anyone else out there has had a similar experience.
The shortest story that I can make of it is that no matter what I do my keeper rate in AI servo with the 5D3 is seriously below what I can get with my 7D. I have used all the modes and tweaked all the setting but generally speaking the camera will not keep focus on my subject. More often than not focus jumps to the background (fence, buildings, etc.). I have tried several experiments with slow moving traffic and I get similar 'jumpiness' in this and similar scenarios which should prove fairly easy for any AI servo. If I focus on a static subject and just pan the camera I get similar results as well.
I gave it a lot of time because at first I thought it was just part of the learning curve but now I am convinced that there is an issue with the camera or, at least convinced enough to send it in to get checked. I would be interested in knowing if anyone else has had a similar issue with the 5D3 (or any recent Canon body for that matter). I'm also wondering what could be causing this. It would seem to me that AI Servo would be something that would either work fine or not work at all.
I'm very interested in what you folks might have to say.
