Though a pair of pano-cameras can be used to shoot 3D panoramics, a single camera setup is often more desirable considering the ease of handling. One of the noteworthy models is made by
Manfred Graumann. The details of the camera can be found
here .
This camera utilizes a Meopta body similar to that used by
Razzledog. The lenses are a pair of Mamiya Sekor 4.5/55mm with shutter speed from 1-1/500 sec and B(ulb). The camera shoots a pair 24x56mm transparencies.
To know more about early models of stereo panorama cameras have a look at the book "Stereoscopic Photography" By Arthur W. Judge. A limited preview version of it is available
here.
