Rokinon's newest 14mm prime is not only its first auto focus lens engineered for Canon, but it also is its first model to offer weather sealing. Built for the rigors of professional use and uncompromised optical performance, it easily meets or exceeds the performance characteristics of other professional / “luxury” ultra-wide angle lenses, and is the most affordable with a MSRP of $999.00. Designed from the ground up specifically for Canon EOS Digital Full Frame DSLR's, this ultra-wide offers a bright F2.8 aperture, uncompromised optical performance, sealing against the elements and a rounded seven blade aperture for pleasing bokeh and star effects. Compared to others in its class, the Rokinon 14mm F2.8 AF Prime for Canon EF Mount provides reduced size and weight, a wider angle of view of 116.6 Degree, and its new AF design takes advantage of the minimized weight and movement of the focusing lens group for accurate, faster, and even quieter in operation than competing systems.
