SOURCE: Mamiya 645 pro shutter doesn't fire

First thing that comes to mind on this camera is that it's a modular camera. This means the film back can be changed mid roll so there is what is called a Dark Slide between the film back and the body.

The dark slide needs to be removed before the camera will function. Also depending on how "new" the film back is there may be a dark slide holder/sleeve on the back side of the film back.

So you remove the dark slide and slide is into the holder so first you don't loose it and also it doesn't get bent.

SOURCE: my 645 1000s shutter buttons

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.

I just bought a nice used Mamiya twin lens C3 but the shutter is locked up. There is a small metal piece holding the shutter release from moving. Not sure how to un-lock, seams to be a safety device of...


The vertical shutter sliding lever gets locked if the film doesn't get advanced to the next frame, and the mode selector is set for single exposure. You can't trip the shutter unless you have film in the camera and you forward the film to the next frame. That should allow you to release the shutter with the sliding lever.

if the shutter is jammed just off the device,and slightly pull the shutter door with your hand 3-4 times.apply a drop of oil on both the sides.and then on the device.and check it will work.
and for the replacement off the handle you will have to check on the old device that where are locks in the back you just have to remove that locks,also check for the hidden screws in the centre or back of the handle.which may be blocking it to be removed easily.

thanks.

Mamiya 645- broken mirror stop.


If you find a source, do share. I am looking for the shutter stop to be fixed on my Mamiya 645 Pro TL as well. I saw someone online made one out of metal himself... seems like the way to go, but lot of effort.

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

First check id the sync card is good .... that can be checked by shorting the outer rim and inner pin ... if the flash fires than the cord is fine .... there would be a problem with the jack in the camera.... try cleaning the jack a bit ...sumtimes carbon deposits give problems

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.

Shutter stays open on mamiya 645 M


Get any crud from the battery out of the works with pH-neutral stuff and q-tips or lint-free towels, and see if it works (without film; might as well check current drain with a bench supply instead of a battery, too) once you've done a satisfactory job of that.  Then visit a shop so they can see if the shutter timing is tolerable...and perhaps sometime you can load film in again.
