I have a very nice AE-1 with everything working, but the shutter stays open for seconds. Sometimes it won't close until I pull the battery out. The shutter speed setting has no effect. Any ideas? Thanks! - Rien

    \$\begingroup\$ Hi Rien and welcome to Photo.SE! When you mention Sometime it won't close... when is this sometimes happening? Just at random? \$\endgroup\$ Mar 14, 2020 at 6:06
  • \$\begingroup\$ Can you please confirm if the shutter stays open or if it's just the mirror not returning? \$\endgroup\$

  • \$\begingroup\$ Does the camera have a self timer, and is it on? Also, I remember a similar situation when the mirror would stay locked up if the battery was low. \$\endgroup\$

Sounds like you have it on Auto mode in a low light situation, or your battery may be getting low. Check those things first.
If it's not low light or battery you may need a partial "Clean, Lubricate, Adjust" (CLA) maintenance or a repair.

  • \$\begingroup\$ The Canon AE-1 is a shutter priority camera. Given Marinus H.B. Vesseur has correctly identified his camera, there is no automatic mode that would control the shutter speed. \$\endgroup\$
