Yesterday,when I tried out my 1DX,there were times when the auto=focusing had a hard time working or not working at all.A few times,I have to press the shuttet button(Both Vertical and Horizontal)harder to take a shot and there would be a few times when it wouldn't work.This is the first time that it has happened.By the way,this doesn't happen most of the time.Like I said,it was only the first time this has happened.It only happens about 5% to 10% of the time since yesterdayWould anyone out there know on what is happening.Is there anything wrong with the lens contact of the cameraOr,is there something wrong with the shutter release of my camera?You see,I tried out different lenses and still get the same problem.
Thanks.
