The new Sigma 50-500mm f4.5-6.3 DG OS HSM has now arrived in the UK. Presently available in Sigma, Canon and Nikon fittings, the Sigma 50-500mm f4.5-6.3 DG OS HSM has a suggested retail price of £1399.99. The Pentax and Sony versions will follow shortly, said Paul Reynolds of Sigma Imaging (UK) Ltd. Incorporating Sigma’s original Optical Stabiliser function, the Sigma 50-500mm f/4.5-6.3 allows sharp hand-held shots at shutter speeds approximately 4 stops slower than would otherwise be possible. Four SLD (Special Low Dispersion) glass elements provide excellent correction of colour aberration, the company says.

Sigma Press Release

50-500mm f4.5-6.3 DG OS HSM High Magnification Ultra Telephoto Zoom Lens with a 10x zoom ratio

Sigma Imaging (UK) Ltd is pleased to announce that the suggested retail price of the new 50-500mm f4.5-6.3 DG OS HSM is £1399.99. This new lens is now available in the UK in Sigma, Canon and Nikon fittings. Pentax and Sony fit will follow shortly.

This is a 10x high zoom ratio ultra telephoto zoom lens incorporating Sigma’s original Optical Stabiliser function.  This lens covers a wide range of focal lengths from 50mm to 500mm ultra telephoto.  The OS (Optical Stabiliser) function offers the use of shutter speeds approximately 4 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 SLD (Special Low Dispersion) glass elements provide excellent correction of colour aberration.  The Super Multi-Layer Coating reduces flare and ghost 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 HSM (Hyper Sonic Motor), ensuring quiet and high speed AF 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 ?95mm and the lens is supplied with a step down ring enabling digital cameras with an APS-C size image sensor to use an ?86mm filter.
