xx nc 1000 bellows
« Thread started on: Apr 8th, 2017, 4:08pm »

I recently acquired what appears to be a Mamiya NC1000 Auto Bellows unit (tilt/swings + double cable release), Slide Copier and Bellows Stand as shown at:

http://www.butkus.org/chinon/mamiya/mamiya_nc1000/mamiya_nc1000-3.htm

They're in mint condition and in the original styrofoam slabs (bellows stand has original outer box). I was going to hack it to fit Sony Alpha mount and enlarging lens but it's such a beautiful set I hate to see it mauled.
Any offers... or suggesting how it can be adapted to Sony A mount without destroying it.
I have fond Mamiya memories having started with a 1000DTL, graduated to a C330 and ended with an RZ.

Welcome. Congratulations on your good fortune. Hopefully someone with more complete experience will happen by and can answer your questions more definitively.

In several other threads I have noted that Fotodiox has made adapters from Ma/Ze lenses (E and EF series) to various digital cameras, including Sony Alpha (Minolta AF-mount). Because the Mamiya bayonets are roughly compatible rear caps and the infamous bubble cases for the ES series are interchangeable it's worth a try in your case. In another thread the result was not satisfactory, but that was with a lens, not an appliance.

If you have played with this rig at all, you will have noticed that the bayonet can be rotated by loosening a set screw. What is undocumented is that with another turn or so the collar can be completely removed, opening up the possibility for fabricating multiple camera adapters for the same standard. If it were me, I would start with a Pentacon-6 to Sony A adapter and open up the P-6 end with a grinder, then drill and tap a hole for the set screw. wink To be sure, other solutions involving 3D printing or metal lathe work also exist that don't require mutilating the original rig, based on this connection.

At the other end, all you need is a Mamiya P-adapter, a M42 to M39 reduction ring, and a large number of enlarger lenses are immediately compatible. With a little luck, some of them might even be useful for portrait work, and with a bag instead of a bellows, architectural if not landscape.

When I became interested in movements, I went in a slightly different direction. All things considered, I came to the conclusion that the M645 rig would be more flexible and more useful for me. For one thing, I already had a good sample of M645 C series lenses, most notably the C 45/2.8 S, the C 70/2.8, and the C 210/4.0 N.

The consideration is this: when movements are involved, it is desirable to use lenses designed for formats at least one "size" larger than the target. For example, for an APS-C sensor, satisfying tilt-shift photography needs a lens designed for 36 mm x 24 mm, and better yet 6 cm x 4.5 cm or 6 cm x 6 cm. In my case, using a M645 bellows opened up the use of medium format and enlarger lenses in the front and 6x4.5cm, 36x24mm, APS-C, and 4/3rds cameras in the back.

If I had not had the M645 lenses, I would have pursued the enlarger lens route like you because this covers even more potential than what I have.

So these are my thoughts and I hope they are helpful. Please let us know what works or doesn't work for you.

Thanks for your suggestions. I'm currently using a Sinar rig but I thought a slightly smaller format would be less cumbersome for shooting negs with digital camera. I'd hate to have to take a grinder to this little jewel. One thing I really like about it is the film copying unit with the flip back diffuser that has rise/fall. It appears that this bellows set is identical to the Contax version which sells for $$$ on ebay. I'll take your suggestion and head over to the Fotodiox site.

I'm glad I could help.

Just to be clear, I was suggesting grinding out the adapter, not the original part. =^0

What happened?

Enquiring minds want to know. smiley

Seeing as you are already familiar with a Sinar rig, your eyes might have glazed over for the rest of what I had written. I wouldn't blame you, since what you already have is much more flexible, albeit massive.

If you haven't discovered it yet, there was indeed someone very interested in this.

Thanks for your interest. I was unable to release the camera mount from the bellows as you suggested nor was I able to locate a P-adapter (though one was part of a larger package being sold on ebay) before I left Florida for the EU for a few months. You're right about the Sinar rig being massive but mounting the Sony a900 was made easier when I was able to mount it to a Sinar lens board using a simple T-mount and an "M48 to M42 48mm - 42mm male-to-male coupling Ring Adapter for Filters" found on ebay (after grinding a few mm off the hole in the board) as a retaining ring. I'm leaning towards using a 24MP Sony aps-c sensor camera with Live View as the throat of the FF camera and adapter create slight vignetting. I'll be back in Florida in October at which time I'll reassess.

This is a slow-motion conversation, so I hope you don't mind if I take my time with each response. 8^)

After a little more research, I have learned that the macro rail which I own is representative of later versions. Please forgive my ignorance. Although I have not had one literally in my hands, it appears that earlier versions had cast metal standards (I assume aluminium), which is quite different from the extruded metal with modular fittings like the one which I own that became available after the introduction of the M645.
