Test Fotos, pics, Rollei isco S Projar 2,5 90mm, Projektionsobjektiv, projection projector lens used as taking lens, adaptiert auf olympus pl1. Wilhelmshaven 2013
Why using projector lenses for photography ?
Projector lenses share many of the design constraints as enlarger lenses but with some critical differences. Projector lenses are always used at full aperture and must produce an acceptably illuminated and acceptably sharp image at full aperture.
Adapted by using helicoid.
Pl use the link, unfortunately pics are not on my harddrive.

Great,

I have a Schneider Ultra-Cinelux 75/2 projection lens, which I´d like to adapt to Nikon F mount, if possible. The lens-to-sensor distance is about is about 57- 59 mm, because at least 11-12 mm extension is needed to get infinity.

Planing to buy a helicoid or something, but what parts are you using?

I glued a small m42 helicoid on an cmount adapter. So u will get easy an adapter for Braun , werra, altix etc., too.
