Canon 1D mk3 - Err 99 in cold conditions
I have a somewhat aging Canon 1D3 that has served me well since purchasing it several years ago.
Shortly after, Canon issued a notice offering free repairs to the shutter/mirror box which I took them up on as I had been seeing an Err 99 message when pressing the shutter button.
Now, however, the same error still appears. Despite testing with various lenses, cleaning contacts etc the only variable I can see that has an effect is temperature.
I shoot wildlife and so I'm often outside in low temperatures. I end up having to detach the body, stuff it in my jacket and warm it up with my body heat to get it working again.
It seems ridiculous that this should affect the operation but I can't see what else it could be.
Would the internal/date battery have any affect on this? I thought about replacing that to see if it made any difference.
Any advice or suggestions would be greatly appreciated!
