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.

I bought a second hand Mamiya 645 Af but as soon as I load a film it shows a error message ERR 01 .... what is that ?


From the manual:
"If the error display is not canceled when the shutter release button is pressed again, insert the Dark slide, half-press the shutter release button while pressing the roll film holder's manual film advance button to wind up the film, then contact your nearest Mamiya agent or service center."

If you need a manual, you can download one from

Light leakage detected from my second hand PRO TL especially at low shutter speed (<1/15 sec). Details are as follows: a) appeared at lower third of a frame; b) spread out evenly from 3 points lying...


It sounds like the aux. curtain that covers the film when you're focusing either is not properly lowering, or is damaged somehow. You can remove the back and look through to see if you notice any light coming through. If you do, consult a tech. You'd only notice it on frames because mid-frames wouldn't remain in the light path long enough to be affected under most circumstances. It'd likely be a tear/nick in the curtain. Or, it could just not be completely be closing.

It could also be an issue with bad seals in the film back, or between the back and body, or even a crack somewhere in the back or the body itself. If you can't find a leak in the curtain, try keeping the dark slide in right up til you take a shot in, taking it out as soon as you're ready to shoot, replacing it before you wind, etc. to minimize the amount of time light could come from the anywhere but the back - to try and narrow down the location of the leak.

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.

Blank roll of film


Two possible problems:

1. Film did not wind on. 2. Shutter not opening.

Easy to test with camera back open. Load a film and fire the shutter a few times each time with winding on, to see if film is winding correctly, at the same time you should be able notice if the shutters are firing, eight of them in succession makes a bit of noise.

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.

My Mamiya RB67 triggers and shutter lease lever works but film advance lever doesn't move. Trigger button fired several times but film advance still showing 1.


This is not the best solution as it indicates a faulty film back. The film should advance without resorting to activating the film-wind release lever. That is only for intentionally advancing a partially exposed roll of film. Make sure the multi-exposure lever is not engaged and that the counter does advance and the red mark disappears as you advance to an unexposed frame.

I took a roll of pictures but the film came out blank. What did I do wrong? or what could be wrong w/the camera?


Please say what model of camera you're using.

You may not have loaded the film properly so that it wasn't wound forward after each exposure. Sometimes the film leader isn't picked up by the wind-on mechanism. Check the frame indicator moves as you wind the film on. Also operate the shutter without film and with the back open. You should see a flash of light through the lens if the shutter operates.

RZ67 with new battery, lens set, 120 film back set but we get all the time a yellow led warning and the shutter does not work


A yellow led indicates the wind lever isn't cocked, or a weak spring hasn't returned it to the fully up position. A red led says pull out the dark slide.

Orange Warning Light


I recently had a similar problem and found the answer to be the shutter release on the lens itself.

When the using the shutter release, (mirror up feature), on the lens the shutter release, screw in portion, in the lens will actually will pop out to accomidate for the cable release.

There will be a small red circle around the base of the area where the cable release would screw into.

Try pushing that back in. Worked for me.

Good luck,

James

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.
