Model 11r is a special version of the 11el (later 11si) for the REVOX-AUTOCARD microfiche document storage system.

It takes images in the 11.5 x 16.5 mm format which makes for about 130 pictures on a 135-36 film.

Differentiating points :

• The lens mounting bayonet is ~1 cm thick, the camera was at the correct distance from the document when the Macro-Switar 1.9/50mm standard lens was at set at infinity.
  
  
• Special ground glass
  
  
• 90° angle viewer made by Minolta



• the exposure meter was fed by an external 6V transformer that was plugged into the modified M flash socket (indicated by a red dot). There was no internal battery.

Serial numbers go from 60601 to 60698. Some of these bodies were later factory-retrofitted for the normal 24x36 format.
