Voigtlander Nokton 50mm f/1.1 Lens (Leica M)

An exceedingly fast lens, the Nokton 50mm f/1.1 from Voigtlander is a versatile normal-length prime for M-mount rangefinder cameras. The bright f/1.1 maximum aperture is well-suited to working in difficult lighting conditions, and also affords extensive control over depth of field for working with selective focus techniques. The optical design employs high refractive index glass to help control spherical aberrations and various distortions for a high degree of sharpness and clarity. Additionally, a 10-blade diaphragm is featured, which helps to produce a smooth bokeh quality, and the manual focus design enables working with subjects as close as 3.3′ away.
