Universal Panorama Camera Viewfinder

STOP! DO NOT USE, REVISION IN PROGRESS TO CORRECT AN ERROR


Universal Panorama Camera Viewfinder is a viewfinder system suitable for wide to normal lenses on panoramic cameras. Currently the development is geared towards 6x17 panorama cameras and cameras with multiple 6x framing options.

I made a fatal error in the telephoto finder therefore scrapped that design entirely as I can't make it work with this type of lens combination.

Development Background

I was designing a panoramic point and shoot camera which also converts to a roll film back for use on my panoramic field camera. So I needed a viewfinder system for use in point and shoot mode.

The 120 roll film back can also use film plane masks to allow me to shoot in 6x17, 6x14, 6x12 and 6x9 formats. That meant I'd need flexibility in the design to be able to use various formats and lenses, and I'd need a large objective lens not only for a bright viewfinder but also to have a wide enough element to accommodate a range
