Grind-o-Ramas by Olivier Alonzo

 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. 

I thank Olivier Alonzo very much for sharing the information. You can visit his Flickr Gallery to get the details of construction of these cameras and see example photographs taken by these great cameras.
