Greetings! I’m new to this forum and hoped someone out there might have done this part replacement. When manual aperture control began failing, I cleaned camera and lens contacts and tried multiple lenses… to no avail. The thumbwheel works flawlessly for every other function, point to the lens contact bridge assembly as the culprit.
Have any here replaced this part, and if so, were any special tools or procedures required?
The 5D2 is likely no longer supported by Canon for repair.
My recommendation is Mid West Camera repair.
