High ratio ultra telephoto zoom lens covering a standard range focal length to telephoto and incorporating Sigma’s original OS function.
This ultra telephoto zoom lens covers a range of focal lengths from 50mm to 500mm ultra telephoto. This lens is equipped with Sigma’s unique OS (Optical Stabiliser) function. This system enables hand held photography for many types of subjects such as motor sports, aeroplanes, close-up and wildlife. Four SLD (Special Low Dispersion) glass elements provide excellent correction of colour aberration throughout the entire zoom range. Incorporation of HSM (Hyper Sonic Motor) ensures quiet and high speed AF, while allowing full-time manual focus override. The addition of the optional APO TELE CONVERTER produces a 1000mm ultra telephoto zoom lens.
Covering a range of focal lengths up to ultra telephoto This lens is ideal for many types of photography such as motor sport, aeroplanes, close-up and wildlife. By rotating the zoom ring, it is possible to change the focal length easily from a standard focal length to an ultra telephoto range. This lens has an equivalent angle of view of a 75-750mm lens * when used on a digital camera with an APS-C size image sensor *The angle of view varies depending on which camera the lens is mounted on.
Sigma’s own unique OS technology The lens is equipped with Sigma’s own unique OS (Optical Stabiliser) function. This system offers the use of shutter speeds approximately 4 stops slower than would otherwise be possible, making telephoto shooting easy. Mode 1 is ideal for general photography and Mode 2 is designed for panning subjects such as racing cars. 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 anti-shake function. 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. *For Pentax and Sony mounts, it is not possible to use the AF and the built-in OS function of this lens when attaching it to film SLR cameras as well as Pentax *ist series and K100D. *When using the OS function of a lens with a camera which incorporates a stabilizer unit, please turn the camera’s stabilizer unit off. *For Nikon and Canon mounts, Optical Stabilizer (OS) function will not work with film SLR cameras except Nikon F6 and Canon EOS-1V.
Excellent Optical Performance This lens features four SLD (Special Low Dispersion) glass elements, providing excellent correction of colour aberration throughout the entire zoom range. The super multi-layer coating reduces flare and ghosting and ensures high contrast images. This lens is equipped with a read focus system that minimises fluctuation of aberration caused by focusing. High image quality is assured throughout the entire zoom range
Close focusing capability This lens has a maximum magnification of 1:3.1 (at the focal length of 200mm). It enables photographers to get close up to small subjects and eliminate distracting parts of larger subjects.
HSM (Hyper Sonic Motor) The rear focus mechanism and HSM (Hyper Sonic Motor) ensures quiet and high speed AF as well as full time manual focus capability. *AF will not function with Sony and Pentax cameras that do not support HSM.
APO Tele-Converter (Optional) The addition of the optical 1.4x EX DG APO or 2x EX DG APO Tele Converters produce a 70-700mm F6.3-8.8 MF ultra-telephoto zoom lens or a 100-1000mm F9-12.6 MF ultra-telephoto zoom lens respectively. * The Pentax mount Tele Converter is not compatible with this particular lens.
Easy Operation and Handling This lens features a Zoom Lock device to eliminate “zoom creep” when the lens is tilted down. When the lens is set to the 50mm focal length, it is remarkably compact and provides easy handling. A removable tripod socket (TS-31) is included making it convenient for handheld photography. The Rear Focus mechanism makes it possible to use the custom bayonet "Petal-type Hood" which prevents extraneous light from degrading the image quality. The lens has a 95mm filter thread and is also supplied with a step down ring enabling digital cameras with an APS-C size image sensor to use an 86mm diameter filter. *It is not possible to use a Polarising filter with the step down ring. If you attach a Polarising filter, you may not be able to remove it again from the lens.
