Ok so I have a 9 month old 5DMKII. Everything has worked fine until today. I was finishing up a day of grad photos when I get the error. I did what the screen told me (turn off camera, remove battery etc..). Nothing really worked. I did what it asked, even tried different lenses, cards, batteries..nothing. I still could shoot a few images, and then the camera would go into error 20 again. Sometimes I could get 2 pictures in before it happens, the next time it could be 30, and the next time no pics at all before the error.
So I called the local store I bought it at. They won't replace it but will send it to Canon Canada for me. (Not 100% sure what the difference is for them to do it other they say they could get it done possibly quicker, and they'll give me a loaner camera...albeit probably an old Rebel since she told me it won't be another FF).
So before shipping it to the city to get sent to Canon, I tried the usual, seemingly bull****, exercise of removing lens, battery, and memory card and letting the camera sit for an hour or so. What happened after that was interesting as I have shot off 252 images so far without the error coming up.
So..is it at all possible that this routine actually fixed my problem? Or am I just getting led on by the camera? I have to shoot a wedding in a little over 3 weeks and I'm afraid the camera won't be back from Canon. I also have a 5D backup that recently had the mirror fly off of it (which i know Canon will cover...but once again quite the wait).
What should I do? Is the camera fixed? Or should I risk the wait and take their loaner in the meantime?
