The 14mm F2.8 AF lens is designed for high-resolution, well-corrected imagery with the most advanced Nikon Full Frame image sensor cameras. It can also be used on APS-C Nikon models where it will provide a 21mm equivalent focal length. State of the art manufacturing techniques and an advanced optical design (15 Ultra Multi Coated elements in 10 groups including 2 Aspherical, 1 Extra-Low Dispersion, and 4 High Refractive Index) minimize aberrations, control distortion and provide excellent resolution. The new Rokinon 14mm Lens is also more affordable than others in its class and also provides a slightly wider angle of view of 116.6°. The ergonomically designed aluminum alloy housing incorporates a M/AF switch that allows the choice of fast and quiet autofocusing or full manual focus control. In addition, when in AF mode, a manual focus override feature is available for fine tuning focus after the lens has autofocused. Additional features include weather sealing, a rounded seven blade aperture for pleasing bokeh and star effects, a built-in lens hood, and a padded lens pouch. It is the perfect for real estate interiors and exteriors, astrophotography, landscapes, and travel.
