Buy Camera SA - Sigma mm F2.8 EX DG OS APO HSM (NEW) This latest version of the Sigma APO mm F2.8 EX DG OS HSM is pleased to announce the inclusion of Optical Stablization(OS) which is critical to equipment sporting this focal range allowing for hand-held tele-photography and the use of shutter speeds approximately 4 stops slower than would otherwise be possible. Sigma's new splash-proof feature is also included preventing dust and precipitation from getting inside the lens. One SLD and two FLD glass elements provides maximum correction of chromatic aberrations. The super multi-layer coating reduces flare and ghosting, and the lens design incorporates an inner focusing and inner zooming system to ensure sharp images throughout the entire zoom range. Improved optical performance provides excellent correction of sagittal coma flare and ensures ultra-high resolution, comparable to a fixed focal length lens. The HSM (Hyper Sonic Motor ensures quiet and high speed AF, while allowing full-time manual focus override. A truly unique product which is a rarity in the photo industry, this lens is the only lens of its kind on the market; a professional zoom lens that also features a fast aperture. Most professionals own the standard 300mm 2.8, but they also have to carry a shorter zoom lens for those times when the subjects move closer. That means fumbling around switching lenses or carrying a second camera body. The amazing Sigma zoom lens let you instantly determine the picture composition you want without having to change your vantage point. Imagine photographing courtside at a college basketball game and having the versatility to zoom in on a player's face or hand and then instantly zoom back to capture the entire player making his shot. You can do it with the Sigma APO mm F2.8 EX DG OS HSM. The aperture remains constant at F2.8 throughout the entire zoom range. The addition of the optional APO tele converter produces an ultra telephoto zoom lens with AF Features Designed for use with full frame digital SLR cameras. May also be used with smaller APS-c size sensors Splash-proof feature protects the lens from the effects of harsh weather conditions Offers Sigma¿s OS System (Optical Stabilization) allowing handheld photography even in low-light situation HSM (Hyper-Sonic Motor) ensures a quiet & high-speed auto focus FLD glass elements with performance equal to fluorite glass for compensate for colour aberration Specifications Lens Construction 23 Elements in 18 Groups Angle of View degrees Number of Diaphragm Blades 9 Mininum Aperture fF22 Minimum Focusing Distance cm cm / in in Filter Size (mm) 105mm Maximum Magnifications 1:8.1 (at 200mm focal length) Dimensions(Diameter x Length) mm x mm mm/4.5in. x 11.4in. in Weight g / 104oz.
