Maintenance Notes: Resolving the "Canon Squeak"
A common issue with aged AE-1 Program bodies is a high-pitched squeak during shutter release caused by dry mirror governor gears. Servicing involves applying a micro-drop of synthetic oil to the mirror gear mechanism via the bottom plate without contaminating the shutter curtains.
