With Technicolor Schneider 3D lens, how to determine prime lens focal length?

[Don Furr]

I have run many old over under titles on the tech lens.

I've run a dozen or so T3d titles with the Technicolor lens. My issue was finding the perfect focal length to fit my screen. Didn't happen so I went back to the Sirius lens.

The tech system was 3 primes and then combinations of magnifiers

That's what I thought. I have all three plus the magnifiers but only the smallest focal length worked but only with the large schneider zoom lens allowed it to almost fit the screen. Also because of the lens size, the Sirius was easier to install Dolby 3D filters on.

Resurrecting this thread after 2 years. When there was a choice between Technicolor 3D (35mm) and Panavision 3D (35mm) systems, most theatres who were not ready for digital 3D choose the Technicolor 3D system so.
Panavision dropped out of the race.
I'm looking for a theatre operator who choose the Panavision 3D and still have the ISCO Panavision filtered 3D lens. I'm in the market to purchase your lens.
