Wind / shutter issue (2nd try to post)

Hi. My 645 Pro, has suddenly stoped cocking the shutter. With power wind it runs though a whole film in two winds. I have tried three backs (all 120) and replaced the battery.

NO warning, was OK then this.

It sounds like there is a problem with the frame counter in the film back itself. Try operating the camera with the back removed and on multi-exp to check the shutter functions.

My 645 1000s shutter buttons wont pop back up.this is my 1st mamiya


You might want to check and make sure the battery is still good. If you purchased the camera used and didn't change the battery then this might be the case.

But in the mean time this is what you need to do:
1st-make sure that the shutter speed dial is set to any shutter speed other than the red circle w/red ring. If your camera is set to that it will drain your battery when not in use since it is designed to be an automatic setting. I set mine to 1/125th to do this push in the circular dial on the side and at the same time turn the knob.

2nd- locate the 2 levers on the opposite side of the shutter speed dial. Once you found them then position the back lever all the way forward towards the setting for "MULTI" and position the lever towards the front straight up.

3rd- then wind the film crank till it won't wind anymore and depress the shutter, if it is wound and the shutter release is still stuck then skip to the fourth step, if something happened and you heard a click then still proceed to the next step because no the shutter release will be temporarily stuck.

4th-Once both of these levers are in this position there should be a red button just behind the shutter release button on the top right side of the camera.... drum roll please...."Push the red button" what you should hear is a rather loud click, this click is the mirror releasing allowing you to: 1 wind the film crank and take another picture and 2 this also now allows you to see through the lens again (assuming that you have a lens on the camera).

In Conclusion: without a battery that is fully functional in the camera this is how the camera will operate once you get a battery for your camera then reposition the levers on the side of the camera opposite of what I suggested (this will be the normal operating mode for the camera with a battery) then when you wind the film crank and depress the shutter everything will function normally.

Hi , I have a Canon AE-1 camera and I'm haviving a problem with the film advance lever . It seems to be stuck . It will not advance. Have you ever come across this problem before? Thanks ,John.


Canon AE-1 35mm SLR is a manual focus camera EOS is Canon's designation of auto focus EOS stands for Electro-Optical System. The problem you are experiencing is caused by several little things that throws the camera, wind and cocking leaver out of synchronization or simply come to the end of the roll. There is a frame counter window just to the left of the shutter release behind the shutter speed dial. Also if you have just loaded film in the camera it may not be seated correctly check by releasing the rewind button, wind the film back but not all the way and open the camera to restart the film.

Hi, I was taking pictures with my camera and I turned the handle to get to the next picture and the button we press to open the shutter (capture the picture) I can push it but it wont click. Please tell me...


Sounds like the shutter has not fully cocked, which often happens when you get to the end of a film and the film advance won't move on a full frame. Try the film rewind crank(gently). If it is not able to turn either way, then you have used up a film and have to rewind it and remove it from the camera. You will then be able to advance the film wind lever to finish cocking the shutter and it will fire as normal.

35mm slr praktica bca shutter problem.


1) Open the top cover.
2) On the film advance gear, the shutter winding lever is attached to it.
It has screw adjustment there. Unscrew the screw ( not all the way out ) You will need to adjust the wind travel and make the length of the wind lever ( made of spring steel) shorter and tighten the screw.

Just starting out with medium format. We bought a second hand Bronica SQ-A from a reputable dealer but the shutter will not **** in 'Normal' 'single exposure setting'. Cocks fine in Multi-exposure setting,...


Sounds like a problem with the single/multi "switch".
Film should not wind on in "multi" setting.
Back to the dealer - if he is reputable, he will get it fixed.

Mamiya 645 Super mirror locked in open position


My mirror somehow got stuck open too, I removed the power winder and grasped the pins in the middle of the silver wheel underneath used to wind the camera. Turn this clockwise until it stops and shutter is completely closed. Test fire camera after. If it doesn't work make sure you wound it all the way.

The shuter is jamed.


The first thing to check are the batteries make sure they are good.

Second thing to check, are you at the end of the film?, I have had lots of customers think they have a 36 exp film in the camera, only to find it is a 24 exp running out of film will stop the shutter and winding from re cocking

Third thing to check if the batteries are good is the position of the mirror, if it is stuck in the up position it may be that the shutter has just hung up, this happens when the camera gets a little olde and the grease in the shutter mech dries up and the shutter blinds get a bit stiff.

A shutter overhaul will fix this but you may be able to free up as a temporary measure. Follow the following steps.

1. Remove the film from the camera.
2. Open the back cover.
3. Hold the camera so you are applying a little pressure on the wind on lever.
4. Very gently and slowly press your thumb onto the shutter curtain material about 5-6mm, just enough to apply a little tension to the material but not enough for it to come out of its side locations.

If the shutter has just hung up this extra tension will cause the mirror to come back down and then allow you to carry on winding.

Sears ks super camera.


You'll have to remove the bottom cover. Either the mirror box or the shutter are stuck. re-cocking it is possible by moving the wind stop clear of the bottom portion of the film advance shaft.

Film advance lever


Your camera is cocked but since the shutter is not working you cannot release it and hence your film advance mechanism does not work. ME-super will work without batteries in full manual mode so set your shutter to B and try to release it. If the shutter will not release in B mode then the shutter/mirror box will need servicing : rubber components in the mirror box mechanism have perished and need replacing. After that your camera will be fine for another couple of years.

67 type II winder problem


This is not a simple repair - if the wind lever is "ratcheting", parts will have to be replaced. If the wind lever is "free-wheeling", there might be no film in the camera, or the counter isn't working ( it has to be at #1 or above to cock the shutter ). It's a job for a repair shop.
