Author Topic: Lens barrel for 35mm anamorphic lens Scott Stark Film Handler Posts: 8 From: Austin, TX, USA Registered: Nov 2015 posted 11-29-2015 12:21 PM                     Hi all, my first post here, and a pretty out-there question. I have an old 35mm tabletop movie projector with lots of Chinese lettering on it, made in Hong Kong by "ME SING ELECTRONIC CO." according to the only marking I can find on it. It works fine. I would like to mount an anamorphic lens, but the lens barrel is too small in diameter, about 3/8" smaller than the lens. I don't really know how to use this - should I mount the lens on a tripod in front of the existing standard lens, or do I need to find a lens barrel that's wide enough for the anamorphic one? If the latter, any ideas where to find such a thing? The existing barrel is about 2-3/8" and the ana-lens is about 2-3/4" in diameter. Thanks and sorry if this is a dumb question.  |  IP: Logged Richard Fowler Film God Posts: 2392 From: Ft.

That is a Shanghai Harvest projector of which there are many models and marketed under different names.  |  IP: Logged Scott Stark Film Handler Posts: 8 From: Austin, TX, USA Registered: Nov 2015 posted 11-29-2015 02:19 PM                     Ah ok so does the standard lens stay there and the anamorphic is mounted in front of it, or do I remove the standard? (guess I could try it out, right?) -- thanks Richard.  |  IP: Logged Steve Kraus Film God Posts: 4094 From: Chicago, IL, USA Registered: May 2000 posted 11-29-2015 02:33 PM                    The regular lens would be in the barrel in the projector. You might want a different focal length. Generally a shorter focal length for flat and a longer one for Scope, the specifics depending on your screen size and throw (distance to screen). But even in a "don't care / just fooling around" home situation, you might find that your existing lens is too short and creates a picture (expanding as you move away from it) too large to fit through the anamorphic. There is probably a minimum focal length for Scope.  |  IP: Logged
