Samyang 12mm F2.0 ED AS NCS CS Lens - Micro Four Thirds Mount is a perfect wide angle lens for Micro Four Thirds cameras.

The Samyang 12mm offers an equivalent wide angle of 24mm on Micro Four Thirds (MFT) mounts. A fast aperture of f/2.0 allows shooting even in lower light conditions. Optical construction of the lens comprises 12 elements divided into 10 groups including one aspherical lens (ASP) and one hybrid aspherical lens (H-ASP). There are also three lenses made of ED glass, offering superb performance. Technologically the Samyang 12mm lens is the most advanced Samyang lens to date.

The Samyang 12mm features Samyang’s nano crystal anti-reflection coating system (NCS). These coatings provide even lower reflection factor than Samyang's UMC coatings. The NCS coating technology offers exacting process to apply anti-reflection coating more evenly on the surface of the lens. Other benefits brought by the nano crystal layer include improved light transmission, increased resistance to reflections resulting in maximum image contrast. This is applied to 2 elements in the 12mm lens.

The 12mm is a great lens for landscape photography, interior and architecture photography and astrophotography where a high quality wide angle is desired. It features a removable lens hood and 67mm filter thread. It is compact and lightweight, weighing around 250g making it a perfect solution for compact mirrorless interchangeable lens camera systems.

Samyang Optics’ Nano Coating System
For the first time in Samyang Optics history, NCS (Nano Coating System) is used to lower reflection rate more effectively to provide higher contrast.

Extra-wide-angle lens of professional level
Realised wide-angle of 83.0° and low distortion to create crisp images for landscape and architectural shooting.

Bright aperture (F2.0)
F2.0 enables taking vivid and sharp photo even in dark environments.

Glass aspherical lens (AS)
Provides the high quality and contrast image even when aperture is fully opened by revising colour aberration.

Low distortion lens (ED)
Lowers unnecessary light dispersion to effectively dropped colour aberration.

Aperture with almost full circle
6 aperture blades creating almost a full circle when closed express ray beautifully as starlight.
