Mamiya rz67 cocking lever problem - Mamiya RZ67 ProII Medium Format Camera

SOURCE: 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

Hi there

I have researched your problem. I have located the online version of your camera and attached the link here:

It seems like the following cause might fit your symptom:

Is it possible that the small lever on the side might be set to multiple exposures. (See number 22 on the online manual that I sent the link for!)

Good Luck! and let us know how this works.

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.

I have a PDF version I'd be willing to send you if you still need it. What's your email address?

Some of the gears are probably loose. I would suggest you take it to a professional camera shop.
