Hi everyone hope someone can help here, I have the above lens, fitted to a 7D MkII. I had the lens at 600mm the other day, and the 7D2 set to AI servo, with center point + expansion points. However, the combo refused to auto focus and kept switching to manual focus (I lost some decent shots). Switching the camera to just centre point AF cured the problem.
Yes, I have the dock, and the lens has the latest firmware.
Anyone else had the same problem!!!!!!
Cheers
