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)!

I was pretty sure of that but didn't want to make any assumptions grin

I don't own this particular lens, or any CS series lenses, but if it is constructed like the E 50/1.7, the threaded ring/nut is in the back.

Here is an image of the front of the group:

You'll notice the fungus on the bottom left of the front element. The outer notches are for removing the whole group front the lens body. The inner stepped ring holds the front element in place - that is where the problem lies!

Hi guys,

Ive started to clean up some of my old lenses so I can use them on my NC1000s. I have a beautiful 50mm that has some fungus underneath the front element.

I've removed the front lens group but I can't seem to separate the group to get access to the bottom of the front element. There aren't are spots to insert my spanner wrench & I've tried a rubber stopper with pressure.Can anyone help with some knowledge?

Thanks in advance,

Goose


A photo might be helpful. I can't imagine how you removed the whole cell without first removing the decorative ring.

As a last resort, you might need to CAREFULLY drill two small holes in the ring for the pointy bits of the spanner to fit in.

Got another ZM in excellent condition, with 28mmE 3.5 wide angle, another 50mm 1.7 and a tamron zoom (46a) with fungus but with a nice adapter (I swear the tamron I'm cleaning just now is the last one .. this will stay in a dry sealed box for a while, tamron zooms are not difficult to open and dismantle and then remount but lenses never really clean. In comparison I could clean the three original mamyia lenses I have now with a few passes of pure ethanol. tamron lenses actually seem to release filth when cleaned with ethanol, while all my other lenses, canon, contax, leica, clean in a pass or two).



Good news about finding a donor so quickly.

Sorry to hear about your bad luck with Tamrons.

I finally saw a battery holder, the two batteries are connected in series that's why i couldn't use my improvised adapter I had done some days ago.

I think making a correct one won't be difficult just need a small piece of spare teflon and some junk metal. Files I have plenty.

In others words there a slight play when the lens is mounted. Is this normal for the NC1000?

I hope a made some sense in describing my issue.

Hi Alex,

Movement of "a few millimeters in each direction" is definitely not normal. Please check that the bayonet on the lens and the receiver in the body are both properly fastened; that might be a simple fix. Otherwise, the latch is worn, and fixing that could be a bit more complicated.

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.
