NOKTON is the title given to fast lenses with an open F value of F1.5 or less among Voigtländer lenses. In the 1950s, when the first Nokton appeared, it was positioned as a lens that enables to shoot even under low light conditions. Now, the merit of fast lenses in modern times, where the sensitivity of image sensors has increased, is that the large bokeh at open aperture can be used as a photographic expression.
The NOKTON 50mm F1 Aspherical VM is an ultra-fast standard lens that achieves the brightest F1 as a full-frame interchangeable lens for Voigtländer. In addition to suppressing the interruption of the optical viewfinder on a rangefinder camera, the total length is limited to 55.0 mm (tip to mount surface) while keeping sharp image even at the open aperture. In order to satisfy the design goals of both lens performance and styling, we have adopted an in-house produced GA (grinding aspherical) lens on the first surface of the lens.
The reason why we designed and manufactured a GA lens, which is more difficult to control the production than a general mold aspherical lens, and time required for the manufacturing process, is that it is possible to use high melting point and high refraction glass materials which cannot be used in mold manufacturing method. By manufacturing an aspherical lens from a glass material with a high refractive index, it became possible to simplify the lens configuration while ensuring high performance and a lens with a sharp styling with a short length was born. In addition, by adopting a floating mechanism that moves a specific group of lenses to the optimum position according to the shooting distance, stable image quality can be obtained from the shortest shooting distance to distant motifs.
Uses GA (grinding aspherical surface) lens
A GA (grinding aspherical surface) lens produced in-house is used on the first surface of the lens. It is possible to simplify the lens configuration while ensuring high performance, and achieve both high-level image quality and condensed styling while maintaining an ultra-large aperture.
A fearless and practical style
In addition to suppressing vignetting of the rangefinder by suppressing the total length to 55.0 mm (tip to mount surface) despite the ultra-large aperture of F1, it also features a good balance between the body and the lens from an aesthetic point of view.
Beautiful bokeh with 12 diaphragm blades
A 12-blade diaphragm is used to make the holes formed by the diaphragm blades closer to a circle. The out-of-focus part is a natural depiction, and the point light source is not a polygon but a round and soft bokeh.
Dedicated metal hood included
The attached metal hood has a bayonet-type fitting and can be mounted in reverse when stored. It is a convenient specification to carry without compromising the compactness of the main body.
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 appropriate torque, focusing with a smooth operation feeling is realized. It enables fine focus adjustment.
Bayonet VM mount
A VM mount compatible with the Leica M mount is used for 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 rangefinder 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 full-frame 35mm format. In addition, it achieves a very compact style compared to interchangeable lenses for single-lens reflex cameras.
