Samyang AF 14mm F2.8 EF / Rokinon AF 14mm F2.8 EF Overview

Manufacturer description: This first EF mount autofocus lens from Samyang (sold under the Rokinon brand in the US) encapsulates the brand's universally respected optical technology, especially in the wide angle lens category. From a total of 15 lenses in 10 groups, 7 special optic lenses have been chosen in the production of this lens, to maximize the image quality. The use of 2 aspherical lenses, 4 high-refractive lenses, and 1 extra-low dispersion lens minimizes distortion and various aberrations while producing crystal clear resolution.

The minimized weight and movement of the focusing lens group enables quiet and pleasant autofocusing with high accuracy. This compact Samyang AF 14mm F2.8 EF weighs only 485g without lens caps and hood, is weather-sealed and a built-in AF/MF switch increase usability.
