Canon AE-1 Troubleshooting

The Canon AE-1 is a 35mm single-lens reflex film camera. Canon released the AE-1 in 1976. The Canon AE-1 uses a electromagnetic focal plane shutter with a speed from 1/1000 to 2 seconds.

Battery Needle Will Not Move

"The camera has no power.''

Battery is Not in Correctly

The Canon Ae-1 runs on a single 4LR44 or PX-28 battery. It is possible that the battery was put in incorrectly. Open the battery hatch on the front of the camera. Check to see that the positive and negative nodes on the battery align correctly and that the battery is in all the way.

Battery is Dead

It may be that the battery is dead. This can be check using a voltage meter to check the battery's charge or by simple replacing the battery with a fresh one.

Corroded Terminals

It is possible with the age of the Canon Ae-1 that the terminals for the battery have been corroded. If this is the case try to remove some of the rust off of the terminals. A good way to remove the rust is to soak just the terminals in coke.

Shutter Will Not Function Properly

"Shutter does not cycle correctly with the film."

Replace the Battery

One of the main reasons that this happens is that the battery in the camera is almost dead. The function that cycles the film take a significantly less amount of power, then it does to make the shutter function. Simple replace the battery.

Clean the Electromagnet

The shutter in the Canon Ae-1 funtions with an electromagnet. As the camera gets older the camera can accumulate metal particles on the electromagnet. These particles will cause the electromagnet to not have enough power to function the shutter. To fix this you will need to remove the bottom and spray pressurized air into the small plastic container that houses the electromagnet.

Cleaning Inner Mirror and Lens

"Looking through the view finder the lens appears dirty''

Clean with Pressurized Air

The simplest way to fix this problem is to remove the SLR lense. This will expose the inner mirror and lens. Take a canister of pressurized air and spray it on the mirror and lense. This will remove dust and dirty without the risk of scratching either the lens or mirror.

Replace the Mirror and/or Lens

It is possilbe the the inner mirror and/or the lens have been scratched or cracked. If this is the case they will need to be replaced.

Light Exposure on Film

"There is light exposure on the pictures after they have been developed."

Rewind Film Fully

This may be because the film was not completely rewind before being taken out of the camera. Be sure to rewind the fill fully before opening the film compartment.

Check Foam Seals

There is a foam light seal inside the film compartment that can go bad. This is often the case with light exposure problems becasue the Canon Ae-1 is over 20 years old. Replace the strip of foam with a new piece and the problem should be fixed.

Nothing Worked

The solutions above didn't work or you have a different problem not listed.

If you use pressuized air in mirror box you seriously risk dust/hairs in the viewfinder, use only a single duck feather dipped and flicked vigoursly in 91% alcohol to remove dust on mirror. It is a front surfaced mirror and easily scratched. You may use this same feather on bottom of fresnel is plastic and also easily scratched or milked white if using too much alcohol.....honestly best left to someone very experienced as you can easily create permanent damage.

My film advance lever isn't making the noise it's supposed to when you advance it. What's wrong with it? Is it just broke?
