The only think I can see on my back screen is "Err 20 Shooting is not possible. Turn the power switch to<OFF> and <ON>again or re-Install the battery."
I try everything another lens or CF card...but after a few shots the problem is back again !
Don't know what to do...I will return it and hope to get a new one
I'm using CANON since years now and it is the first time I have that kind of problem.
Did anyone here having the same problem ????
