I did try USCamera website, but no hits.
Depending on the exact version of the lens USCamera may have a parts list (generally under $10) and then the actual apr number could be searched for on eBay or general internet search..
Website is USCamera-dot-com.
Thank you. I did find the part number for the a/m switch assembly, viz: YG9-1073-000. I've tried eBay and also a general internet search without luck. My camera is a Canon t3i - I've thoroughly enjoyed using it; but it has a lot of age and thousands of shots taken. So, I have to decide whether to replace the lens realizing the camera is nearing its end of usefulness or to replace both camera and lens.
Any way, thanks for your assistance.......
I have never tried to replace that switch but getting inside a lens can mess up alignment. Canon would check that after they did any inside repair. Whomever does it needs to also check lens alignment and I doubt most shops have that ability or a DIY person for certain.
The working used lens form KEH is probably the best go.
