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. This is why it turns out a useful tool for sport 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 more compact size of the lens and reduces its weight by approximately 160 grams Samyang 10mm 1:2.8 ED AS NCS CS is the first Samyang Optics lens featuring a nano crystal anti-reflection coating system. This technology provides lower reflection factor than (U)MC system as the coating is now applied more evenly on the surface of the lens.
