Canon AT-1 (Similar AE-1) Shutter Fires Upon Advancing Film Lever

This is an intermittent problem, happens once very ten times film is advanced. I'm testing the camera empty with new battery. I have read something about the shutter magnets possibly being the cause. Can I get more details, a procedure? Is there pictures/schematics of the area needing fixing out there that may help? Anything else to clean when I have it open? THANKS!

No need to look at the schematics. It only will give you a little headache. Replace Shutter release magnet (MG#3). While winding stage the Mg#3 suppose to catch the lever and any dirt or particle may prevent it. Clean it and it shoud take care of the problem. Good Luck -James.

This camera is somewhere between fifteen and thirty years old. It is highly unlikely that spares would be available, and it would be extremely expensive to have it repaired in any case, most artificers familiar with the internal layout having probably retired years ago. Maybe the camera should be retired too ?

If your film was TOTALLY blank then it's been bleached due to a processing error. By totally blank, I mean that there are no frame numbers or other film markings on your blank film. Otherwise, you simply have an unexposed film.

First, operate the camera with the camera back open, hold the camera up to a bright light and operate the camera as you look into the back of the lens. If you see a brief bit of light coming through as you operate the shutter then the shutter is admitting light into the camera and so you should have got some kind of an image unless you failed to correctly load the film (very common).

Unfortunately, there's no way to tell unless you try another roll of film. Once the film is loaded, turn the rewind crank gently to take up slack film and take a few pictures; each time you advance the film the rewind crank should turn a little. If it doesn't then the film has not been correctly loaded as the film leader has not engaged onto the take-up spool. If so, open the camera and re-engage the film. If it clearly has engaged, then the take-up spool is failing to rotate when the film is advanced: try taking a few shots and winding on the film with the back open. If the film is not advancing then you have a faulty Lomo. This is extremely common as it is a plastic toy camera with atrocious build quality and materials and is the FishEye is only designed for paltry ten rolls of film lifespan.

A final check for film which has not advanced through the camera is if the rewind is extremely short when the film has finished.

Battery indicator reads empty when batteries are fully charged


It looks like your question was cut short... all I see is "Battery indicator reads empty when batteries are..."

With my experience with the Pentax *ist DL, I think the problem is probably that brand new batteries still show "empty" on the indicator.

Chances are that you are not using the CR-V3 camera batteries in your *ist DL. I have tried 2400mAh NiMH rechargable batteries and brand new alkaline batteries in an attempt to save money.

Neither lasted anywhere near as long as the CR-V3 batteries! While you may be paying $15-$20 for two CR-V3 batteries, they last a LONG time!

One of the advantages of DSLRs (and digital cameras in general) is that you save money by no longer buying film and paying for developing/prints. But, even at $20 for two CR-V3 batteries, I save money! I am able to take several hundred photos on a pair of batteries (I think the manual says 500+) instead of $10-$15 ($2-$7 for film + $8 dev/print) for every 24-36 photos!

Mamiya 645 AF back won't advance film.


The battery in the film back is only used to supply power when the back is off the camera, when it is on the body power is supplied by the six batteries in the body so try them and also make sure the film insert is properly seated.

Pentax SF10 Camera -- double exposure


If you press the film release button like you are going to rewind exposed film you may be able to activate the film advance lever to cock the camera so you can take another picture, and the film should stay on the first exposure allowing you to re - expose it. I would underexpose each image 1 F stop because.you are exposing the same film twice. Double exposures are always an iffy proposition and anything can happen. After the second exposure cocking the film advance should allow the film to advance once again. You might test this on the final pictures on a roll in case the camera won't start advancing the film after you try it. This way you won't blow a whole roll worth of pictures testing it.

What does A ERR mean?


There are several situations when this message happens and the camera locks up, and almost none of them has anything to do with the cause stated in the camera manual: film DX coding error. (If it is truly a DX-coding error, manually setting the ISO speed of the film should solve the problem. This could happen in cold weather.) Scenario One: when using Alkaline batteries and the batteries are almost exhausted, and yet one continues to shoot. The battery may not have enough power to complete the shutter firing operation (which usually includes: mirror up, close down diaphragm, shutter fire, mirror down, open diaphragm, advance film, and charge the shutter for next frame). The camera could be lock up in the middle of the operation, left with a dimmed viewfinder. Usually an indication appears quite early if one pays attention: when the batteries are almost exhausted, the film advance becomes noticeably slow. In normal situation film advance is very fast and one cannot distinguish it from other noise such as mirror flipping. When the batteries almost exhausted, the film-advance could take almost 1 second, and the noise of film advancing has been mistakenly identified by some as "beep". I think those is the result of over-adjustment for the Premature Battery Indication problem. This scenario is particular to using alkaline batteries, due to the peculiar behavior of the alkaline battery: even when its power is almost exhausted, it still has a pretty high voltage. Solution: replace the batteries and fire the shutter once should solve the problem. I am pretty sure this is normal, since it happened to me several times, and I once deliberately repeated this happening. Scenario Two: At the end of a roll, when the remaining film is too short for one more frame but long enough to fool the camera, the camera could end up with "Err" message. Solution: rewind the film and load with the new one, and possibly fire the shutter once could solve the problem. (This has never happened to me, but summarized from other’s reports.) Scenario Three: I've heard of two reports: happened in the middle of a roll, with sufficient battery power. I have no idea what’s going on. (Could be really a DX-coding problem, which does not necessarily occur just at the beginning of a roll.) Solution: probably should send the camera in for a check. (Also, both reports of this problem occurs while using Kodachrome films.)

Takes a picture when film advance lever is moved


The magnets that control the shutter are the likely suspect. Dirt and debris can cause them not to hold properly. Hence, it fires the shutter when you advance the film. It is something you can repair yourself. I can describe the procedure if you are interested.

Big problem


The only thing i can suggest is pushing the film rewind button on the bottom of the camera body. crank the film back in to the canister and drop a new roll in. Ihave experianced this problem once or twice when I rolled canisters from bulk film and it would get jammed.

Good luck
