Leica M1 'Wolf Set' (endoscopy)

The Leica M1 'Wolf Set' (endoscopy) is a specialized variant of the M1 body produced by Leica between 1959 and 1964. Essentially a standard M1 modified for medical endoscopy, it featured a modified body design, often including a longer base plate and specialized controls to accommodate endoscopic lenses and accessories used in medical imaging. Sharing the core mechanics of the M1, including the Leica M bayonet mount and a simplified, rangefinder-based viewfinder compared to the M3, it represents Leica's application of its reliable M-system technology beyond traditional photography into the demanding field of medical diagnostics. Its production was limited, intended solely for professional medical use rather than general photography or videography.
