My about one month old 5D III appears to be unresponsive at times. It was purchased from an authorized US dealer. The lack of responsiveness could be a few seconds or a minute or so that the pressing of the shutter does not do anything. This happens with flash (580 EX II) or without flash. Initially I thought it had to do with processing time which was due to the high # of fps I was shooting at swim meets specially when I was doing both RAW + JPG simultaneously. Now that I am saving in RAW only, and single shots without a burst, it still behaves the same way. This incidentally is happening with any lens on the camera and any shooting mode. The lenses that I mostly use are 70-200, 24-70, 50 1.2 and 24-105. I have not tried it with any other lenses or my 600 EX-RT flash that I got this Christmas yet.
I know this could be a user error as I have not cracked opened the manual to the camera. Please do NOT give me a hard time on that as my wife has taken care of that on behalf of all my fellow FMers already!
My concern is if this is possibly a bad copy, and if so, perhaps I should return it and get a new one.
I appreciate any thoughts you might have on this.
