Three types of exteriors to choose from
Two types of exterior metal are available: Type I, made of aluminum and weighing 188 g for light weight and mobility, and Type II, made of brass and weighing 284 g for a thick and heavy feel, with a choice of black paint or silver plating finish (Type I is only available in matte black paint.).
Minimum focus distance of 0.5 meters
The lens focuses beyond the minimum rangefinder-coupled focus distance of 0.7m all the way down to 0.5m. This feature is especially useful when using the lens on a camera with a live view function.
Manual focus for reliable focusing
Employs a very precisely machined and adjusted all metal helicoid unit lubricated with high quality grease to realize smooth focusing operation with just the right amount of torque. This enables very precise focusing.
Bayonet type VM mount
Uses the VM-mount lens mount compatible with Leica M-mount. Not only can this lens be used on rangefinder-coupled cameras, but design-wise it also balances very nicely when mounted on mirrorless digital cameras with a mount adapter.
Installed with a focus-coupling system
The high-precision rangefinder coupling mechanism enables precise focusing in focus critical situations such as when shooting at or close to maximum aperture.
Imaging circle that covers full frame format
The lens features a generous imaging circle that covers the 35 mm full frame format. Furthermore, its size is extremely compact compared to interchangeable lenses for single-lens reflex cameras.
