Samyang has announced the 10mm F2.8 ED AS NCS SC, a wide-angle manual focus prime for APS-C format cameras. It's the company's first lens to feature nano crystal coating for increased light transmission and reduced internal reflections. With a 15mm equivalent angle of view (20mm equivalent on Micro Four Thirds), it'll be made in mounts for all current SLR and mirrorless systems. The lens features an integrated petal-type hood, and the aperture is set manually by a ring on the barrel. It'll go on sale at the end of January 2014 at an RRP of £469.99 for Nikon AE mount, or £429.99 for all other versions.
The prototype of this lens was first shown at Photokina 2012, but since then the design has been refined. According to Samyang the main changes have been the addition of the Nano Coating System (NCS) and the integration of the lens hood - apparently saving 160g over the original removable-hood design.

New Samyang 10mm 1:2.8 ED AS NCS CS
 |
December 6th 2013 - Samyang release new wide-angle 10mm 1:2.8 ED AS NCS CS lens in APS-C format.
Samyang has introduced a focused development program to obtain the highest possible optical parameters and reduce the product's size at the same time. These efforts resulted in the latest version of Samyang 10mm 1:2.8 ED AS NCS CS lens featuring parameters and capabilities comparable to the best wide-angle prime and zoom lenses on the market.
The new Samyang 10mm 1:2.8 ED AS NCS CS is an ideal tool for indoor, architecture and landscape photography. It provides an exceptionally wide field of view of up to 109.5 degrees and rectilinear image mapping function. Owing to a fast f/2.8 lens speed you can also use the lens in low light conditions as well as sports photography and photojournalism purposes. The product's optics comprises 14 elements divided into 10 groups, this includes 2 aspherical AS lenses and one lens made of extra-low dispersion glass. During development works on the prototype version the lens was fitted with an embedded lens hood which ensures a more compact size and reduces its weight by approximately 160 grams*.
* - applicable to a version with Canon E mount
NCS (Nano Coating System)
The Samyang 10mm 1:2.8 ED AS NCS CS is the first Samyang Optics lens to feature a nano crystal anti-reflection coating system. This technology provides a lower reflection factor than (U)MC system as the coating is now applied more evenly on the surface of the lens. Benefits brought by the nano crystal layer include better light transmission, increased resistance to reflections and higher contrast, and all of this translates into supreme optical resolution of the lens.
The lens will be available from the end of January 2014.
The suggested retail price for the Nikon version is £469.99 inc VAT
All other fittings carry a suggested retail price of £429.99 inc VAT
