Description

RARE! MC Photographic AMAZING bayonet lens mounting system for HORSEMAN & SINAR
This is a super rare bayonet mounting system for Horseman and Sinar cameras. Check out the operation of how it works in the photos. There’s a little finger-tight screw for tightening and loosening, then you twist the lens slightly to release, then mount a new lens. The conviences of not having to have each lens mounted to a full board can’t be understated. It’s incredibly well-made and hard to find anymore. it’s also completely light tight, as any lensboard should be. You’ll love it.
You’ll notice that in the photo with the rings all together, the finish is so matte-black, it’s hard to see the seperation between rings. The black finish is one of the reasons they work so well.
Please look at all the photos as they clearly show the cosmetic condition of the board and rings, as well as how it works. I appologize if I am unable to answer questions that are answered in the text or photos.
I list my auctions as “No Returns” so I do not have people buying things to try them out; but if there’s a real problem then I am open to solving it.  I am confident in my description and the quality of the mounting system.
