Leica DG Nocticron 42.5mm f/1.2 ASPH Lens

The Leica DG Nocticron 42.5mm f/1.2 ASPH is an interchangeable lens for the LUMIX G based on the Micro Four Thirds System standard. The lens will be available for £1,399 from March 2014. 

Certified by the world-renowned Leica, this new lens has a maximum aperture of f/1.2 and features optical image stabilization (POWER O.I.S.) along with full time Auto Focus.

The new lens system is comprised of 14 elements in 11 groups and uses two aspherical lenses, one ED (Extra-low Dispersion) and one UHR (Ultra High Refractive Index) lens. The aspherical lenses suppress spherical aberration and distortion. The ED lens enables sharp, high contrast description without colour bleeding to the corners while the UHR lens enables high optical performance that renders an image with uniformed descriptiveness from center to edges as well as downsizing of the lens unit.   

Nine blades give the aperture a rounded shape that produces an attractively smooth effect in out-of-focus areas when shooting at larger aperture settings and the aperture ring on the lens barrel allows direct, intuitive control over aperture settings.


Panasonic's Nano Surface Coating technology has been adopted to the Leica DG Nocticron 42.5mm f/1.2 ASPH. Reflection is dramatically minimized at entire visual light range (380nm-780nm) by applying the extra-low refractive index coating with nano-sized structure on the surface of the lens. It results in a super clear image with dramatic reduction of ghost and flare.

POWER O.I.S. (Optical Image Stabilizer) is also found on this lens which effectively compensates for not only small, fast movement but also large, slow movement, making it easy to capture super clear shots even when shooting in low-lit situations such as in night time or indoors.

It incorporates superior inner focus system, which enables excellent resolution and contrast from close-up to infinity. The inclusion of newly developed stepping motor makes the focusing action smooth and silent for use in both still and video recording. Notably the performance of Auto Focus is far superior to the phase-difference AF when a fast lens with smaller F value is used. When mounted on LUMIX G cameras, users can take advantage of the high-speed, high-precision Contrast AF system.

The Leica DG Nocticron 42.5mm f/1.2 ASPH features a metal design, including the hood, and a highly reliable metal mount.
