Your Eiki takes a lens with a 42.5mm barrel. So there are a wide variety of lenses that will fit it, of different lengths.
In MOST cases, the anamorphic lens is an adaptor which fits over the front of your existing lens. So you might, have, say, a 100mm Isco lens on the projector, and you screw an adaptor ring onto that and then you screw on a Sankor anamorphic adaptor over top of that lens. This works well for long throw applications but you can run into issues if the spherical lens is too short. There are SOME anamorphic lenses that just slide into the projector and replace both halves. The original Bausch and Lomb 16mm Cinemascope lenses were this way. For the most part these are kind of lousy and some of them only focus properly with a narrow range of throw lengths. So... the first question here is how big an image do you want with how much of a throw, and what kind of spherical lenses do you have and what kind of anamorphic adaptors do you have? The 35mm anamorphic adaptors are selling cheaply today and they can usually be adapted for 16mm use. Many of them are very sharp. However, they are generally pretty heavy and may need external support. The Sankor lenses aren't really all that sharp and they tend to cost good money these days but they are light and convenient. --scott _______________________________________________ FrameWorks mailing list FrameWorks@jonasmekasfilms.com https://mailman-mail5.webfaction.com/listinfo/frameworks
