Help! Direction? Assistance?
My 5d mkIII is acting badly, started a week ago, err 20. Brought her home like an injured bird as the battery pull in the field and power on and off did nothing. Pulled the lens and the mirror was raised a bit, pressed down as if I was trying to move a butterfly's wing and no movement, pushed up and it went all the way up easy. Pulled the battery and all was well. Did some test shots, noted an odd addition to the shutter sound but thought it was ok and thought I would get a second opinion. Took her to a local shop known for excellent work, they gave her a thumbs up, "spring tension is good" and "no odd noise".
Just the other day I was shooting my wife in a Double Road Race (a 10k and then 5k run) and found that she (the camera not my wife) was locking up again with err 20 then err 1 and then err 20 again. I flipped to silent multiple-exposure rather then normal multiple-exposure and found I could get about 10 continuous shots before lock up and error, yeah! And of course the odd shutter noise was gone. Dah, silent mode.
Purchased July 2012, yes, out of warranty, spoke to Canon and they asked that I send it to Irvine for non warranty repair.

The camera could be mistaken for brand new, she is my baby and receives all the benefits associated with this title! My wife calls her my "other girl-friend".
Last lock up (thought it would not free up too) I saw that the shutter was completely closed and the mirror was all the way up too.
The camera will not perform "manual sensor cleaning" from main menu. And will not lock up the mirror.
When engaging "live View" the mirror lock up sound is normal but the release is when it sounds odd. This is the new odd sound of the shutter movement.
Today I am going back to the local good shop with this new info in hand but I also wanted to see what and if anything anyone here may know on this? Any opinions are welcome? Well, besides someone telling me I should have bought a Nikon.
