The Leica Noctilux-M 50mm f/0.95 ASPH. is the world's highest-speed aspherical lens. It newly defines the limits of the physically feasible and enables to experiment with focus and blur on a level never seen before. The new Noctilux owes its outstanding performance to a combination of special glasses with anomalous partial dispersion, high refractive index glasses, a floating element and two ground and polished aspheres. The latter are individually manufactured in consistently perfect quality.
