The ROKINON 50mm f/1.4 AS IF UMC Digital Photo Lens is a high performance prime 50mm lens, considered to be the "standard" focal length for Full Frame Format, fills the gap between the highly rated Rokinon 35mm and 85mm models. Offering a very fast f/1.4 maximum aperture, low light shooting, action stopping fast shutter speeds, and shallow depth of field control are yours to enjoy.
Providing a "normal" 46.2 Degree field of view on Full Frame (FX) sensor cameras, it?s perfect for everyday photography. With APS-C sensor cameras, it provides a 75mm focal length equivalent (30.8 Degree field of view) and with Canon APS-C sensor cameras an 80mm focal length equivalent (29.0 Degree field of view) which is perfect for portraits. Lens construction consists of nine high performance glass lens elements, with special anti-reflective Ultra Multi-Coating, arranged in six groups including one Aspherical and one Hybrid-Aspherical lens element. All combine to ensure outstanding resolution, sharpness and contrast while reducing ghosting and flare in all lighting conditions. Focusing using the textured rubberized focusing ring is precise, silky smooth and quiet, while its internal focusing (IF) mechanism prevents both changes in length and rotation for easier use of polarizing and other orientation sensitive filters. Additional features include a circular 8-blade diaphragm enabling pleasing out-of-focus highlights (Bokeh) and an aluminum alloy chassis for enhanced durability, a removable lens hood (reversible for storage), lens caps, lens pouch, instruction manual, serialized certificate of quality and one year Rokinon USA warranty. Manufactured in South Korea and engineered for optimum performance, Rokinon utilizes specialized glass types and multi-coating techniques to produce serious tools for photographers and film makers who appreciate high image quality with quiet, silky smooth and complete focusing control.
