nocticronPanasonic has introduced the Leica DG Nocticron 42.5 mm f/1.2 ASPH lens for the Lumix G. This Micro Four Thirds (MFT) lens is the equivalent of 85 mm.

The lens not only has a maximum aperture of f/1.2 but it also incorporates optical image stabilization along with full time autofocus.

Certified by Leica, exceptional high image quality is guaranteed as well as its metal design. The name “Nocticron” was newly defined by Leica Camera AG for this lens.

The lens has 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 uniformity from centre 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. 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 lens. Reflection is dramatically minimized for the 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, says the company.

The optical image stabilizer effectively compensates for not only small, fast movement but also large, slow movement.

The lens incorporates a superior inner focus system, which enables excellent resolution and contrast from close-up to infinity, says Panasonic. The inclusion of newly developed stepping motor makes the focusing action smooth and silent for use in both still and video recording.
