Sigma 50-500 mm F4.5-6.3 APO DG OS HSM Lens

Sigma APO 50-500mm F4.5-6.3 DG OS HSM f/ Canon EOS

The Sigma APO 50-500mm F4.5-6.3 DG OS HSM is a 10x high zoom ratio ultra telephoto zoom lens incorporating Sigma's original Optical Stabilizer function. This lens covers a wide range of focal lengths from 50mm to 500mm ultra telephoto. The OS (Optical Stabilizer) function offers the use of shutter speeds approximately 4 stops slower than would otherwise be possible. 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 color 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. It 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.

Sigma 50-500mm f/4.5-6.3 APO DG OS HSM SLD Ultra Telephoto Zoom Lens for Canon Digital SLR Camera

Sigma's APO 50-500mm F4.5-6.3 DG OS HSM is an advanced optical design of this 10x power high-performance zoom lens that covers the standard-to-super- telephoto range, now with the added advantage of Sigma's own Optical Stabilization which offers the use of shutter speeds approximately 4 stops slower than would otherwise be possible. Sigma is the only one to offer OS for Sony and Pentax mount where the image is stabilized in the viewfinder if chosen. For many photographers, having an all-in-one lens is an absolute dream. Especially for nature photographers, the idea of a lens suitable for landscape photography at the short end of the zoom range, while still having enough reach for wildlife is a great option. Add to that, the ability to close focus on small objects in the field such as flowers and it's the perfect backpackers' lens. Four SLD (Special Low Dispersion) glass elements provide optimum color correction & sharpness throughout the entire zoom range and super Multi-Layer lens coating reduces flare and ghosting and assures high image quality throughout the entire zoom range. With no need to change lenses, there is less chance of dirt or moisture entering the camera and fouling the imaging sensor.
