Automatic aperture setting on canon FD lenses not working on AE-1


I recently bought a canon ae-1 on ebay. I had been using this camera with a friends older canon 50mm lens (silver ring type, not bayonet). When set to the "A" setting, the lens aperture would react according to the light conditions when I took the picture, as it is supposed to do. The problem appears when I try to use the newer bayonet type lens on this camera. With these lenses, the "A" setting alone does make the aperture change when I snap off a picture. If i depress the stop-down lever, the aperture kicks in, but when I wind the film, instead of returning the aperture to full open for the next shot to be metered, it opens and then closes down again. This leads me to believe that the stop-down lever is not used for this purpose. Using a piece of plastic or cork to stop one of the lenses levers, the aperture will do it's job in the "A" mode. Is this normal? Why do these lenses need modifications to work with the cameras they were made for?

You have a case of AE(auto exposure) Unit faulty or getting bad. It suppose to register as it move within the AE unit according to the exposure calculation but somehow it is broken. Technician usualy replace the AE unit and takes care of the problem. It can also be rebuilt if new parts are not available. This requires complete disassembly and mirror box removal. The average cost of repair probably runs around $100. Yes, "A" mode is correct for most of the shots and it was a state of art electronic system and more computerized than you think. It has 3 IC chips in there for precessing and 1 chip for the exposure. All works together for good. -James

My A1 only works when the lens is off the "A" position. Manually setting the apperture it works fine, otherwise it displays a bunch of EEEEEEEEEs....


The AE-1 requires, that when the camera's shutter speed dial is set on A or Auto, that the lense must be set on the highest aperature (22, 32, whatever that lense has). In all other settings you can move around however you'd like.

Value of my av-1


Almost nothing, even if perfect. I've got three of them all for nothing from FreeCycle.

It's a cut-price, aperture priority only version of the AE-1 program and so is not even popular with collectors unless absolutely mint and with all original accessories.

At most, the body only is worth about £10 on a good day, and absolutely nothing if the batteries are flat as the camera cannot then be shown to be in working order and the battery pack costs around £6. Any lenses with the camera will be worth more, but it all depends upon what they are. Canon FD lenses will not fit the later AF Canons though (except for the obsolete T-Series), so are not as popular as they could be.

Answer to your question is, ‘Yes’ we can. Use Sigma FD lenses.

As we know Canon AV-1 has electronically controlled AE (Automatic Exposure) & has a Canon Breech-lock lens mount.

Original generation of FD lenses featured a silver locking ring at the base. Only that locking ring turns to lock the lens to the camera body; the lens body remains still.

In the newer lens system which was introduced with this camera, the user has to line up the red dot on the lens, with the red dot on the camera and simply turned the whole lens clockwise until it clicked into place.

Note: FD-mount cameras could use FL lenses in stop-down metering mode.

Thank you & have a nice day.

Warm regards,
William

My daughter is having trouble with using my old AE-1. She is trying to set the apperture manually but sees no change inside the lense. Can you tell me if there is something that she is not doing correctly...


The apeture is toward the back part of the lens. Shine a light down into the front of the lens and turn the apeture ring, you should see it change size.

Your second answer is the correct one. The seal at the edge of the film/back door needs to be replaced. The foam fails over time, a common problem

Meter on ae1 not working when aperture setting adjusted


On that camera the needle is not supposed to move when the f-stop ring is turned. It should stay on whatever number it is on and you should set the ring manually to whatever the needle points to.

That camera was really not made to be easy to use in the manual mode. I guess Canon thought everyone would just use it in Auto.

To open the back pull on the rewind knob ( pulling up ) until back opens. Check that your 6 volt battery is ok ( ae -1 has an electronic shutter so will not work without a battery ): battery situated on the left hand side of the camera ( if it is facing you ) underneath small flip up door ( lock is at the bottom on the left of the small door ) . Check the battery by pressing the shutter release gently and seeing if your light meter needle moves. No movement ? replace battery. You have two modes for taking pictures : auto which is actually AV ( aperture priority) or full manual : both are set by moving the shutter speed dial on the top right hand side ( underneath film winding lever ).
