Hi, can't you get somewhere some information about the size??
Normally 35mm projectors are quite long throwing ones, which means that the anamorphic equipment for them just works with a small throwing angle.
But do ou have a source for buying such stuff? Recently I tried to get a Super Panatar at ebay. I was outbidded by a few $
That sucked.
I have an anamorphotic lens for 16mm but this does not really work because of the small angle.
In a german ht-forum there is a guy who builds his own anamorphotic lens. He uses prisms which are made of glass and filled with specific oil- as I read about leaking oil problems (I don't say the P word, could lead to some wars here) I knew why.
This is absolutely the easiest way to build a prism whith certain refraction. The guy took glass with special coating to avoid light loss. He calculated a lot and found the parameters for the prisms that he could easily change the strech-factor from 4:3 to 16:9 which means you can use your 4:3 pj for 2:35:1 and 1.78:1.
He also wanted to implement some "neutral" setting which means you can watch 4:3 native without ever to remove the lens.
The last problem he had was, that the oil was quite aggressive and the glue he used to build the prisms could not stand it. So he was looking for a different glue and is still working on it.
There are persons in the forum who will make some building-plan for homemade anamorphic lenses. The material costs are (including the coated glass!) below 250$
Since you seem to seek as desperately for an anamorphic lens as me, shall I inform you when this tryout leads to success?
When I had my first pj - a Sony CPJ 100E... - and then bought my first DVD-Player I thought about having an anamorphic lens for the pj.
