Tamron Adaptall (Leica R) Lens Adapter

Tamron Adaptall custom lens mount attaches your Tamron Adaptall Automatic SLR lens to popular SLR and DSLR cameras. This adaptall mount custom made for Leica R mount cameras. It offers automatic diaphragm and full aperture metering with compatible manual and auto exposure modes (program mode where available).  An additional scale is provided for cameras that use this to display the aperture setting in the viewfinder, with f/22 marked in green for program and shutter priority modes. The f/22 setting has a steadier click stop than the other apertures, and the lens should NOT be set to f/32 (AE) with this mount.
