Features:

• Compatible with all Leica M models
• For all very fast Leica M lenses when the full aperture of the lens is used to apply the shallow field depth to a specific detail of the subject
• 40% increase in the effective measuring base results in a corresponding increase in focusing accuracy
• With 75 to 135 mm telephoto lenses, the clearly larger viewfinder image offers significantly better recognition of subject details inside the field frame
• Roughly 70% of the original viewfinder image can still be seen
• A 0.72x camera viewfinder (M8 models: 0.68x) becomes a 1x viewfinder (0,95x); this combination also allows comfortable viewing of the subject with both eyes.
• Supplied with a black chrome brass retaining chain that can be attached to the carrying strap eyelet
• Supplied in a leather case with a loop that allows the magnifier to be stored on the camera's carrying strap
• Rubberized eyepiece protects eyeglasses from being scratched
• Correction lenses M can be used
