APO-LANTHAR 50mm F3.5 (Type II)
Features
A standard lens with a classical and compact style, bearing the name of "APO-LANTHAR," a proof of ultimate performance. While adopting a maximum aperture of F3.5, the lens is composed of eight elements in six groups, four of which are made of anomalous partial-dispersion glass, to achieve uncompromising optical performance.
Main Features
Apochromatic design
This design thoroughly eliminates various aberrations including axial chromatic aberrations and pursues the ultimate performance in terms of resolution and contrast reproducibility
Classical and compact styling
Slim and stylish design reminiscent of the rangefinder lenses that appeared in the 1950s. All parts are made of metal for superior texture and feel, offering the joy of owning a lens
Two types of exterior variations
Two versions of Type II are available: a silver model with a heavy feel using brass material (body weight: 250 g) and a lighter model with black paint and aluminum material in some parts (body weight: 175g)
Minimum focus distance of 0.35 meters
The lens focuses beyond the minimum rangefinder-coupled focus distance of 0.7m all the way down to 0.35m. This feature is especially useful when using the lens on a camera with a live view function
Focusing click of the rangefinder coupling range
A mechanism is provided to recognize the junction point of the rangefinder-linked range by a clicking sensation during focusing operation
Metal hood and Hood-cap included
The silver model has a metal hood in the same color as the main body and a black metal cap with a pear-finish, while the black model has a black paint in the same color as the lens body
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
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
