APO 50-500mm F4.5-6.3 DG OS HSM
The Sigma APO 50-500mm F4.5-6.3 DG OS HSM is a 10x high-zoom ratio, ultra telephoto zoom lens incorporating Sigmas original Optical Stabilization (OS) function. This lens covers a wide range of focal lengths from 50mm to 500mm ultra telephoto. The OS function offers the use of shutter speeds approximately four stops slower than would otherwise be possible. For Sony and Pentax mount, the built-in OS function of this lens can be used even if the camera body is equipped with an image sensor shift anti-shake system. As compensation for camera shake is visible in the view finder, the photographer can easily check for accurate focus and ensure there is no subject movement. Four Special Low Dispersion (SLD) glass elements provide excellent correction of color aberration. The Super Multi-Layer Coating reduces flare and ghosting, and ensures high image quality throughout the entire zoom range. This lens has a maximum magnification ratio of 1:3.1 (at the focal length of 200mm), making it ideal for close-up photography. This lens incorporates Hyper Sonic Motor (HSM), ensuring quiet and high-speed auto focus, as well as full-time manual focus capability. The addition of the optional 1.4x EX DG or 2x EX DG APO Tele Converters produce a 70-700mm F6.3-8 or a 100-1000mm F9-12.6 MF zoom lens, respectively. This lens is equipped with a petal-type hood to block out extraneous light. The filter size of this lens is f95mm and the lens is supplied with a step-down ring enabling digital cameras with an APS-C size image sensor to use a f86mm filter.
