A fast optic for the 39mm screwmount rangefinder cameras, the Nokton features 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.
A standard L-mount is used for this lens, making it compatible with Voigtlander Bessa R & L cameras as well as classic cameras from Leica and Canon with the venerable 39mm screwmount design. If you desire to use this lens with Leica M, Voigtlander Bessa T or Konica Hexar RF cameras, use the adapter ring (catalog number 45BD209A). This lens retains rangefinder and viewfinder coupling with all the combinations.
