The shutter assembly has failed, a common fault with all older autofocus SLR's. it's nothing to do with the autofocus itself, just that AF SLR's usually tend to have fully electronically operated shutters which cannot be serviced and repaired like older models.

The only fix is to replace it, but it's no longer available and even if you do find one the repair is not economically worthwhile.

If you're not too choosy as to the brand, then free similar SLR models complete with lenses are regularly available on FreeCycle and Freegle. It's where I got all of mine.

I snap a shot on my Pentax zx-7 and the flash will go off but the film doesn't advance, the number on the roll indicator stays that same, and there are no negative being transferred onto the film...


Hi I need more information. After pushing release button, you will hear motor running sound---like mirror goes up and down and takeup spool running sound. I want to try more. First remove lens and set M mode. Push release button. You will see mirror up/down and motor running sound. If you can see these thing, then you have defective camera. Let me know more detail. thanks and best regard!

My Mamiya C330 Pro only gives me 4 photos per roll


A few things to consider:
-Loading: Make sure you are not over loading the film before you start to shoot. I have sometimes turned the film advance too many times and end up cutting down on the amount of usable film.
-Are you loading the film in a dark area and careful to close up the back just after it has started to load to avoid exposing it?
-Shooting: Are you metering properly when shooting? Obviously underexposed images won't develop. You should consider a hand held meter.
-Shooting: Are you advancing the film more than it needs to be after you take your shot? Watch the film counter and feel for that click as it hits the next frame. I have advanced past the next shot many times by accident.
Hope that helps, Matt

What film do you use for a canon af-7s


The Sure Shot AF-7 is a 35mm camera. That means it uses 35mm film (sometimes known as size 135). You can use black&white film or color film, either slides or negatives (for prints).
You may download a copy of the manual here.

Blank Film Developing

you should have at least 6in. of exposed film from the film canister to the take-up spool unless you loaded the film in total darkness.
open the back cover to make sure the shutter is working, reload and give it another try.

Loaded film blank


Chances are the film had quite a bit of curl to it (often a sign of old film) and it was not pulled over quite far enough during auto loading, or perhaps too far and it had too much slack that the take up reel never grabbed it to advance it thru. You're not the first one this has happened to as the auto load is not as reliable as the older style where you had to load the film leader through a slot in the take up reel.

Problem in camera or film roll??


Hey msenile,
It is possible that each frame would have image data imprinted without and image being exposed. This could be caused by the shutter not opening while the camera still exposing the film internally with the image data recorded. It is unlikely that this bad film since the emulsion covers the entire surface of the film and if it were bad the image data would not be recorded either. Another cause of this but very unlikely is every frame was somehow extremely underexposed. This could happen if the camera is set to manual and the light level is low and the shutter speed is set to a fast speed and the aperture is set to a very small aperture. I hope this helps!

Sincerely,
Allan
Go Ahead. Use Us.

My first roll of film came back all blank. Not even one negative was underexposed. I have just bought a Nikon F6 film camara.


Just to make sure, if you do see the picture on your negatives, then the problem most likely lies within the developer. Try somewhere else and see if that works for you. If not, then you can use another type of film. The film could have been mishandled when manufacturered. These cameras don't usually have problems so that would be the last thing I would look at.

Pentax MZ 50 film winding problem


Well, I'm not a camera repairman, but it sounds to me (and probably to you too) that the electronics are damaged or perhaps there's dust in the contacts inside. I also have an MZ-50. There's so many electronics involved and they don't age so gracefully. I would consider buying another one off eBay or you can get a ZX-30 (same as MZ-30) for $75 from Blue Moon Camera & Machine with a 1 year warranty (parts and labor). The best way would be, in my opinion, to get a manual, mechanical camera from the 1970s and put a good lens on it. Those seem to last forever. No electronics to worry about. Advance and rewind the film manually. You can use a digital camera as a light meter to set the aperture and shutter speed. I'm thinking of going this route when my MZ-50 finally conks out.
