The Panasonic Leica Dg Nocticron 42.5mm f/1.2 Asph / Power O.i.s Lens is suitable for the Lumix G based on the Micro Four Thirds System standard. (35 mm camera equivalent: 85 mm). 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 color 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. The popular 42.5 mm medium-telephoto focal distance (Equivalent to 85 mm on a 35 mm camera) is perfectly suited for portraits with rich stereoscopic effect. Together with the high-speed aperture, users can utilize the beautiful soft focus for more impressive, creative shots.
