I have a Canon 7D (mark 1). Recently it started giving an "Error 20". Searching the internet this error appears to be a problem with the mirror movement mechanism.
Has anyone experienced this problem, and is there any solution other than sending the camera back to Canon for service?
My problem is the only service center shown for Canada is the other side of the country (Ontario), which means expensive shipping (and possible loss).
I'm wondering if there's a quick fix or workaround.
