In Grind-o-Rama panoramic conversions, the film gate of a SLR/rangefinder is grinded off, thereby generating a longer film path to accommodate a panoramic exposure
Recently Olivier Alonzo shared his collections of handmade panoramic cameras. Part of the collection consist of Canon 7 rangefinder derived and Wirgin Stereo camera based panoramic camera with coupled rangefinder !!!!
For this Canon 7 body, the lens mated was a Bronica 50mm. Whereas for the Wigin, a Super Angulon 47 mm (also a Mamiya Press 50mm in another construction) has been used with rangefinder coupling, generating stunning sharp 24x92 exposures.
There are also other examples of Mamiya TLR lens based panoramic cameras.
