The 14mm F2.8 AF Full Frame Ultra-Wide for Canon EF-Mount is not only Rokinon's first auto focus lens engineered for Canon, but it also is their 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-wides.

Designed from the ground up specifically for Canon EOS Digital Full Frame DSLR's, this prime 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°, 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.

A total of fifteen elements in ten groups along with UMC anti-reflective coatings are utilized to maximize image quality. One Extra Low Dispersion, two Aspherical and four High Refractive Index lens elements combine for outstanding image clarity, contrast, color fidelity, and high resolution from the center to the corners of the image as can be seen on its MTF chart. Additional features include a durable all metal housing with a built in lens hood, a Manual / Auto Focus switch and full compatibility with APS-C Canon EF Mount Cameras, where it will provide an equivalent focal length of approximately 22.4mm.
