Technical details Leica Noctilux-M 50mm
As the world’s highest-speed aspherical lens, this 50mm Noctilux lens exceeds the perception of the human eye. State-of-the-art optics and mechanical technologies have created a noticeable increase in lens speed, and a floating element retains high image quality even in the close-up range. Vignetting and distortion are even better than former Noctilux generations.
