The Samyang 16mm T2.2 ED AS UMC CS VDSLR lens is a bright ultra wide-angle manual focus lens, designed for cameras and camcorders equipped with CS / APS-C / DX and MFT sensors. Available mounts for Canon EF, Nikon F, Sony A, Sony E, Canon M (EF-EOS M), Fuji / Fujifilm X and Olympus / Panasonic Micro Four Thirds (MFT / M43). This VDSLR (Video DSLR) version was developed primarily for professional filmmaking. The VDSLR version is equipped with a follow focus ring and a de-clicked aperture, which allow the user to smoothly and silently adjust focus and aperture / depth of field during shooting, and to connect to professional follow focus systems. The Samyang is rated in T-stops rather than F-stops, which is customary for cinema camera lenses. The F-number expresses the speed of the lens assuming that it transmits 100% of the incident light. The T-number expresses the actual light transmission, which is more accurate and is the standard for professional cinema lenses. The Samyang 16mm T2.2 ED AS UMC CS VDSLR version is optically identical to the standard Samyang 16mm f/2.0 ED AS UMC CS version. The Samyang 16mm is a rectilinear lens offering superb image quality and low distortion. It is perfectly suited to APS-C sensor cameras for landscape photography and general photography requiring a high-quality wide-angle lens. The wide f2 aperture enables low-light photography. The optical construction comprises 13 elements in 11 groups, with 2 aspherical lenses, 1 extra-low dispersion (ED) element and a hybrid aspherical element, and features Samyang's Ultra UMC multi-coating which ensures excellent light transmission and minimises flare and ghosting. The elements are housed in a solid body weighing approximately 570g, depending on the mount. Suitable for professional and amateur photographers, the 16mm is equivalent to 24mm on APS-C sensors, 25.6mm on Canon EOS (1.6x crop factor) and 32mm on Olympus and Panasonic MFT sensor system cameras. The new Samyang 16mm accepts 77mm filters for attaching ND filters, polarisers or any filter with a 77mm thread, and features a removable petal-shaped lens hood. The Samyang 16mm has a wide ribbed manual focus ring that is smooth and well damped. This allows precise manual focusing, particularly suited to more professional video / DSLR shooting where manual focus is preferred, enabling focus pulling during video recording. The lens is supplied with front and rear caps, a petal-shaped lens hood and a soft pouch. Available mounts: Canon EF, Canon M (EF-EOS M), Nikon F, Sony A, Sony E, Fujifilm X, Pentax K and Olympus / Panasonic Micro Four Thirds (MFT / M43) versions Specifications
