This Voigtlander S-Nokton 50mm f/1.5 is an extreme bright lens, features an all-metal lens barrel construction, and a 10 bladed aperture diaphragm which creates pleasing out-of-focus highlights. Click stop aperture movements at half-stop intervals makes subtle adjustments in exposure or depth-of-field easy.
The Nokton lens is unusual in the rangefinder field because of the use of modern aspherical lens element fabrication technology on the rear element. The lens is constructed with two aspherical surfaces and one SD (super-low dispersion) glass element. This maintains the high level of image quality that rangefinder customers have become used to while keeping a highly competitive price point.
This lens features the "S" lens mount, which allows it to be used with any Nikon rangefinder camera.
