Mamiya 645 Pro TL Medium Format Camera - Answered Questions & Fixed issues


It's been a while since I used a mamilla 645, so forgive me if this is wrong, but I seem to remember the dark slide would only come out with the camera wound on, ready to take a picture.

Probably not, but I would imagine you would need a lens

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.

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.

hasselblad makes a digital back--approximately $20,000 USD (yes, that is 20 THOUSAND) and then you need the adaptor (approx. another $1000-$1500 USD). If you can afford that, why not buy a NEW MAMIYA RZ22 (22 mP) or the 33 (33 MP)? would cost less and already digital.

After loading the back with film, the dark slide is inserted so you may remove the back without ecxposing the film. Suppose you had 2 different back, 1 with b&w and the other has color. You are shooting with color. Load the color film and before shooting, remove the dark slide. After a few shots, you decide to change to B&W, insert the dark slide, change backs, remove that dark slide and continue shooting. This is assuming that you have 2 dark slides, 1 for each back. If you only have 1 dark slide, then the back that is not on the camera needs it if it is loaded with film and the other back will have to stay on the camera.

You probably nees the "P" adapter made to attach the back to the camera. If your item did nopt come with one, you will have to buy it seperately. Go to Mamiya.com and download the owners manual pdf.

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've got the same problem :-( Help would be appreciated.

Those are spacers for equal plane for all corners.

Without the service manual, then you are up the river without ...

Just try to put spacer(s) on one side more than the other and close it up. Now look thru the viewfinder with lenses attached and check for sharpness.

If you're doing lots of cloe-up or macro, then those spacers are needed. If you can't correct problem, just shoot at F5.6 or higher.

You will have to remove or add spacer(s) by using T & E methods.

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.

Problem solved- The camera does not operate correctly unless the battery is in good condition, in place, and all the contacts are clean. In the RZ76 as opposed to the old RB models the components "talk" to each other: via electronic circuits. The back "tells" the camera bod if the dark slide ins in or out and whether the film is loaded or at the end of the roll. If the batter voltage is too low or the contacts are no clean and making full contact the body has no way of knowing the condition of the film backs and the interlocking mechanisms fail to work.

What I did was firstly test the battery under load and discovered that the cell was a bit low. It was a fresh battery but it is a good idea to turn the camera off after shooting in case the is a slight current draw when the camera is idle (?) . I replaced the battery and traced the voltages through the body to see if it was getting to some of the contacts such as the onces on the meter prism which has LEDs to be lighted. I also used an ohm meter to check out continuity- everything seemed to be in order. I then cleaned all the contacts including the battery terminals withl alcohol and made sure everything was dry and clean.

Now- everything works. The camera was turned off overnight and the battery has lost no voltage when tested under load..

This camera is equipped with RB lenses which have no electrical contacts and therefore the camera and lenses can't "communicate" so the meter will not work with theses older lenses.
