The name "Nocticron" was defined by Leica Camera AG for this lens that achieves a remarkably fast f1.2 aperture. The popular 42.5 mm of middle-telephoto focal distance (Equivalent to 85 mm on a 35 mm camera) is definitely suitable for portrait with rich stereoscopic effect. Together with the high-speed aperture, you can utilize the beautiful soft focus for more impressive, creative shots. 9 blades give the aperture a rounded shape that produces a smooth effect in out-of-focus areas when shooting at larger aperture settings
The inclusion of newly developed stepping motor makes the focusing action smooth and silent for use in both photo and video recording. Notably the performance of AF is by far superior to the phase-difference AF when fast lens with smaller F value is used. When mounted on the cameras of LUMIX G, you can take advantage of the high-precision, high-speed Contrast AF system.
