1- I tried to remove battery.....nothing
2- removed lens..and re-attached
3- put in my 50 f1.2 ....nothing
i changed the priority to release...took one shot...then put back my setting or priority to focus..and all was good after that
now i can't reproduce it
I had similiar but different problem
Just bought the camera on 13 March After a few days and around my 50000 shot my focus problem started.
( ps I mainly use 12FPS mode and the 70-200 2.8 is usm and similiar(16-35 2.
or worse(70-300 DO) for other lens)
( I am doing a shooting for the same dancing concert for 9 consecutive days it occur after the 4th day and the first few days were perfectly fine )
from time to time I cannot focus in one shot mode. as soon as switch I back to MF for 1 or 2 shutter release and turn back to AF it works again, then after a while it happen again. and repeatable. The AF ok period seems to deteriorate after another 5000-10000 shot.
Then I start to try the Ai-servo mode. Seems like the first few shot is out then in focus for a long period in ai-servo mode. If I switch back to single-shot the above will happen again.
Any one have any suggestions (take back to repair?)
