The Sigma 50-500mm f4.5-6.3 DG OS HSM lens is an upgrade to Sigma's popular 50-500mm ultra-telephoto zoom, and now includes an Optical Stabilizer which offers the use of shutter speeds approximately 4 stops slower than would otherwise be possible - a particularly useful addition on a lens of this size. The Sigma 50-500mm OS lens incorporates HSM (Hyper Sonic Motor), to ensure quick and quiet auto-focus, as well as full-time manual focus capability. Four SLD (Special Low Dispersion) glass elements provide excellent correction of colour aberration, while the Super Multi-Layer Coating reduces flare and ghost and ensures high image quality throughout the entire zoom range. 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. The filter size of this lens is 95mm, but 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’s DG lenses are designed for cameras with a full-frame sensor, but cameras with a cropped sensor can also take these lenses. These are large-aperture lenses with wide angles and short minimum focusing distances. With an abundance of peripheral illumination, they are ideal lenses for Digital SLR Cameras whilst retaining suitability for traditional 35mm SLRs.
OS (Optical Stabilizer)
This function utilises a built-in mechanism that compensates for camera shake. It dramatically expands photographic possibilities by alleviating camera movement when shooting hand held.
HSM (Hyper-Sonic Motor)
This lens uses a motor driven by ultrasonic waves to provide a quiet, high speed AF.

The key features
Covering a range of focal lengths up to ultra telephoto
This lens is ideal for many types of photography such as motor sport, air planes, macro 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 digital cameras with APS-C size image sensors.
*The angle of view varies depending on which camera the lens is mounted on.
Sigma's own unique OS (Optical Stabilizer) technology
The lens is equipped with Sigma's own unique OS (Optical Stabilizer) 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.
*This lens cannot be used with film SLR cameras with the exception of the Nikon F6 and Canon EOS-1v.
Excellent Optical Performance
This lens features four SLD (Special Low Dispersion) glass elements, providing excellent correction of color 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 minimizes fluctuation of aberration caused by focusing. High image quality is assured throughout the entire zoom range.
The 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 if the Sony and Pentax camera bodies 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.
Hood Adapter HA1030-01 (Supplied)
Hood adapter extends the length of the lens hood and provides more effective shading when used with digital cameras with an APS-C size image sensor.
* When using the APS-C Hood Adapter HA1030-01 with digital cameras with larger than APS-C size image sensor, vignetting will occur. Please remove the hood adapter if you are using these cameras.
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, which is 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 filter size of this lens is Diameter 95mm and the lens is supplied with a step down ring enabling digital cameras with an APS-C size image sensor to use an Diameter 86mm filter.
*It is not possible to use a Polarizing filter with the step down ring. If you attach a Polarizing filter, you may not be able to remove it from the lens again.
