Maybe we should do a Poll. Granted it's a small sample on here, but it would be interesting to find out how many 1DX shooters have been getting err80's.
Yep it is about time that we start talking about a Poll. Let's start coming up with some sort of draft.
1) My 1DX works flawlessly with all lens, battery, and memory card combinations available to me
2) I have experienced Error 80 continuously since I first turned my camera on
3) I experience Error 80 with select lenses only
4) I experience Error 80 with select memory cards only
5) I have not experienced Error 80 but the memory card activity light stays on for prolonged periods of time but has caused no issues so far
6) I have not experienced Error 80 but the memory card activity light stays on for prolonged periods of time and has caused my camera to lock up
7) My camera has locked up from Error 80 as well as the memory card activity light bug (throws no error code)
