A lens optimized for a full-size M-mount sensor, based on the Sony E-mount dedicated lens that was launched on the market as the highest-performance standard lens in the history of Voigtlander. The apochromatic design, which makes the on-axis chromatic aberration of RGB, which constitutes the three primary colors of light, as close to zero as possible, realizes performance that completely changes the values ​​of standard lenses. With a tight style, it also has good handling when using a rangefinder camera.

Main features:

• Apochromat design
  We thoroughly eliminate various aberrations such as axial chromatic aberration and pursue the ultimate performance in terms of resolution and contrast reproducibility.
• An optical glass that drives high performance
  The lens configuration of 10 elements in 8 groups of the mechanical part, 2 abnormally dispersed glass and 2 double-sided aspherical lenses are used, and a floating mechanism is also equipped.
• Compact style
  Reduces the vignetting of the range finder in putting together a full-length short. It weighs 288g (excluding accessories) and realizes light handling.
• 12 diaphragms
  That allows you to enjoy the expression of bokeh The diaphragm blades, which consist of 12 diaphragms, adopt a special shape that makes a circle not only in F2 but also in F2.8 and F5.6. It is possible to draw using “ball blur” such as a point light source.

• Optional bayonet hood
  Offers a beautiful metal bayonet hood LH-13 which is rich in durable option.
• Manual focus for reliable focus operation
  By adopting an all-metal helicoid unit processed and adjusted with high precision and high-quality grease that produces an appropriate torque, focusing with a smooth operation feeling is realized. Allows for delicate focus adjustment.
• Bayonet VM mount
  Adopt the VM mount Leica M mount compatible with the lens mount. Not only can it be used with rangefinder-linked cameras, but it also has an excellent design balance when attached to a mirrorless digital camera via a mount adapter.
• Equipped with a distance meter interlocking system
  The high-precision rangefinder interlocking mechanism enables severe focusing near the maximum aperture.
• Full-size image circle
  We have secured a generous image circle that supports a full-frame 35mm format

The lens is scheduled to be made available in January of 2021 for about $1,150. The hood is sold separately and will retail for about $100 with the same release schedule.
