Camera does not auto switch off by defaultI get that with the EOS M and it's continuous AF setting, but what setting are you talking about on the 1D X?I have 2 batteries and they invariably drain way below the shot number allotted, full charge put in the camera shoot about 100 frames let it sit for a day and some times when i come back to it I wake from a sleep. Shoot 20 or 30 more frames and that horrible last click sound of a dead battery when 15 minutes before, the battery said it was maybe one Bar off full.
both batteries do it. now i can shoot 1500 frame or more on a full battery just letting it sleep is a bit sketchy. My 7D just keeps on going and drains at what i would expect it to a long duration or multiple frames over days.
Please look at your 1DX batter life in a few situations tell em what happening for you this seems unacceptable every-time CPS has it they seem to gloss over the problem.
thank you every one.
You are experiencing this fast drain is because by default the 1dx's autofocus search was set to always on - i.e. the camera wasn't sleeping at all. Hence the drain. Once you've done a good setting customisation you will be fine. This is what happened to me when I first got mine 18months ago then I also saw other member posting the same issue before. Worth a check as it might well be the same cause. : )
