Schneider Kreuznach produce macro lenses for Machine imaging ( robots and such like). They are designed with dual mounts so that you can mount them in any direction you like( no need for a reversing ring). They have a V mount I am not sure if it is the same as Hasselblad's V mount does any one know anything about this V mount?

Should be a medium format Hasselblad lens mount, the only other V-Mount I've heard of is for Minolta Electronic lenses and was never really popular. The Hasselblad V-Mount was introduced with their H-System cameras.

http://en.wikipedia.org/wiki/Hasselblad#V-System

Here is a specification PDF and webpage covering the Schneider V-Mount lenses

Note that Edmund Optics offers quite a few lens mounts from the Schneider V-Mount to popular lens mounts currently in production.

Thanks. I am not so sure that it is the Hasselblad system. I had been looking all through the Schneider Kreuznach site the only hint I got suggested it might be a M37 threaded mount....but it was only a hint. The other reason I don't think it is the Hasselblad V mount is the Hasselblad V-mount was for medium format lenses the SK V mount lenses, produce a range of image circles but almost all of them are smaller than a medium format sensor( but all are adequate for a full frame sensor) Unfortunately You can't buy direct from SK. The only supplier I have found so far is Edmonds optics. A V mount - M42 adapter is around US$75.00. The helcoid focusing tubes are around US$300.00. They are not a cheap option but given the design specifications they might be phenomenal coin lenses.

After I posted I started thinking the Schneider lenses probably aren't medium format due to the image circle also, since I don't have any hands on experience with the V-Mount lenses other than the ones from Hasselblad and Zeiss, defintely check it out, I don't want to mislead you.

Thanks westcoin..you weren't putting me wrong.....I am just intrigued by these "macro" lenses. They appear to be adaptions on enlarger lenses when I read both on the edmonds site and on SK's own site I get the impression that these lenses are designed in such away that they should be brilliant coin lenses. Given how expensive they are ( The APO 90mm is close to US$1400.00) I wanted to know what the mount was I think they would be brilliant on a bellows set up. I have been checking a number of websites and these modern SK products don't appear to be discussed much......so perhaps they aren't as good as I think they could be......or they are just too expensive.

I'd bet the latter, probably so expensive that most amateurs have not tested, reviewed or run tests with them. I have not found any professional reviews in my quick search. They do look interesting though.

Rodenstock has a similar line of high resolution lenses sold under the Linos brand. Most of these are made for high speed optical inspection using line sensors. They are almost all based on existing enlarging/duplicating/scanning lens designs with mounts appropriate for industrial use. That said, as a working amateur I've never had the resources to test these lines of industrial lenses, so they might indeed be very good, but none of the specs I've seen indicate better performance than the commercial APO lenses.

I got the answer. Sending an email helps! The V mount is neither threaded nor a bayonet it is just a 37mm cylinder. The V mount to M2 mount adapter is just a ring with a 37mm hole and three hex screws that are used to secure the lens ( and of course an M42 thread). Very industrial but what more could one expect from a lens system designed for industrial purposes. No wonder Schneider Kreuznach says they are easily reversible, They just have to make sure part of the lens barrel at the front and rear is 37mm in diameter. I would also anticipate that they are physically small lenses not much different to M39 enlarger lenses.
