I have an AE-1 Program.?
Answers:
Check with KEH or B&H or Adorama. You can email the repair service I use at garryscamera@yahoo.com and ask if he has a focusing screen. You can also search on ebay. You may have to buy a "parts" camera and cannabilize it.
Since your camera has long been discontinued this will not be an easy search.
You'd best be careful. The AE-35 has been known to start trouble.
I would suggest you go to an authorized Canon repair station and have them order one for you.
It is unusual that a focusing screen becomes damaged without other dire things happening to the camera, so you may want to the them do a diagnostic test on is as well.
