Welcome to Ron Herron's
Collecting Mamiya 35mm Cameras Forum!

A continuation of the original Forum that started on January 15, 2001


This Forum was created to allow discussions related to the collection, use, repair and service of vintage Mamiya 35mm Film Cameras. It's also a place to show and discuss the images we create with them, digital uses for Mamiya lens, and lots more! Join us, and share in this great hobby! Guests are welcome to visit and view all discussions. However, in order to post a comment or picture you need to register as a Forum Member (it's free).

Your IP address will be checked for spamming prior to approval, but once registered, you'll be able to post responses to any topic, or start a new thread (links for starting a new thread are in each topic area).

When you post your pictures taken with 35mm Mamiya equipment (or lenses), please make them 72-100 dpi jpeg or gif images, and no more than 800 pixels wide, so no one has to scroll to see them (and so any of our friends still with slow connections don't need to go out for coffee while they wait for things to load)!

There are just a couple Zm for sale now on the whole ebay, and at steep prices. If it is as rare as my contax 159, for which I have been looking for a broken twin to cannibalize, so far without success, my guess is that I shall have to create one.

Got some good experience at filing and I have the right tools so I'm not afraid to experiment.

Will try to contact mamyia repair facility in my country but usually such firms keep only spares for cameras being produced.

The repairmen from the USA linked top of this forum seem to have no internet presence now



Two of them are available for "under $20.00", items <162380210160 > and < 381874964068> — the first one with a lens looks like a better deal all around to me.

ZMs show up periodically, often in mobs of 4 or 5 at a time. If you can be patient, it shouldn't take more than a year or so to get a good one or suitable donor with a few choice lenses.

To the best of my knowledge the last remaining service that had a significant stock of replacement parts liquidated them several years ago. With these cameras, we are now on our own regarding fabricating replacement parts.

Mamiya support in any country is pretty much non-existent since they sold off their optical and camera divisions. Some of the later models of the 645 AFd are still supported by PhaseOne.

As I recall, this is not a straightforward part to fabricate, but rather requires several pieces of stamped metal (for electrical contacts) embedded in the nylon carrier. The click to lock is just the flexing action of one of those plates. There is an alignment ridge, but no 'retractable teeth'. Tolerances are rather tight.


Well I think I can use sometricks from knifemaking. A teflon bar with a couple holes, on the back a bent sheet of conducive material, creating contact between the negative of the batteries while pushing the positive side against the positive contact.

Kind of creating it by slow filing a knife mechanism, but improvised. The teflon bar should stay inside by pressure or by a simple adhesive tape.

Something improvised to keep camera going until I find an original spare, nothing for serious work but just to use it in walkabouts

Tomorrow I will try to make a replacement from teflon.

Maybe i will come up with an howto make a functional replacement.

I noted there are two notches in small sheet of metal covering the side of the cavity.

That's where the holder inserts its retractable teeth, I guess.

Check that mechanism.

Post an image of the holder if you can so it can be verified

Hallo, juts got a ZM (without battery holder!) but apparently good shape.

Want to start using it as lenses appear promising, even if rare.

Many years ago I had a mamiya 330 and it worked greatly, but it was basically studio, so I sold it (wrong move).

So I'm back into mamiya shooting

I have compared with a ZE-bellows which I own, and it looks like it really is a CS-bellows in that sale.

BTW. The first bellow among the pictures is a XTL-bellows and the other one is a M42 bellows.

Many regards Per Malare

 9   MAMIYA 35mm - Technical Problems & Questions / Ze quartz stuck at 1/60s  on: Jan 26th, 2017, 02:45am
Started by Rv35 | Post by Rv35
Hello, I recently bought the mamiya ze, it seems to be in a very good condition, clean and no sign of physical damage.

However whenever I pressed the shutter halfway, the speed indicator always lights up at 1/60s. Seems that no matter what the light condition is, it'll stick with that speed.

Any idea how to reset this or fix it?

I've tried cleaning the battery contacts also loaded it with brand new batteries too. Thanks a lot, it would be great if I can get a bit of pointer.
