Sigma's incredible ultra-telephoto zoom lens covering a telephoto range up to 500mm, incorporating Sigma's original OS (Optical Stabilizer) function.

• This ultra-telephoto zoom lens covers a telephoto range up to 500mm and allows photographers to bring the subject close with short perspective.
• Three SLD (Special Low Dispersion) glass elements provide excellent correction for chromatic aberration.
• This lens is equipped with a rear focus system that minimizes fluctuation of aberration caused by focusing.
• HSM (Hyper Sonic Motor), ensures a quiet and high-speed AF as well as full-time manual focusing capability.
• It is also possible to attach the optional APO Tele Converters.

Sigma's own unique OS (Optical Stabilizer) technology
 
The lens is equipped with Sigma's own unique OS (Optical Stabilizer) function. This function uses two sensors inside the lens to detect vertical and horizontal movement of the camera and works by moving an optical image stabilizer lens group to effectively compensate for camera shake. It offers the use of shutter speeds approximately 4 stops slower. Mode 1 is ideal for general photography, and Mode 2 is effective on moving subject such as motor sports etc. 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.

*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.
 
 
Telephoto range up to 500mm
 
This ultra-telephoto zoom lens covers a telephoto range up to 500mm and allows photographers to freely play with the ability of telephoto lenses to ring the subject closer and shorten perspective. The OS (Optical Stabilizer) function provides stable images though the viewfinder and enables the photographer to easily determine the composition with the narrow angle of view. A removable tripod socket (TS-31) is included, which is convenient for handheld photography.
 
Minimum focusing distance of 220cm (86.6”) and maximum magnification of 1:5.2
 
This lens has a minimum focusing distance of 220cm (86.6”) throughout the entire zoom range.  It is convenient for taking close-up pictures.  It is possible to enjoy taking close up pictures of small or large subjects.
 
Excellent Optical Performance
 
Three SLD (Special Low Dispersion) glass elements provide the correction for axial chromatic aberration.  The super multi-layer coating reduces flare and ghosting.  This lens is equipped with a rear focus system that minimizes fluctuation of aberration caused by focusing.  High image quality is assured throughout the entire zoom range.

HSM (Hyper Sonic Motor)
 
This lens incorporates HSM (Hyper Sonic Motor), which ensures a quiet and high-speed AF as well as full-time manual focus override by rotation of the focus ring.
*AF will not function if the Sony and Pentax camera bodies do not support HSM. 

APO Tele-Converter (Optional)
 
The addition of the (optional) 1.4x EX DG APO or 2x EX DG APO Tele Converters produce a 210-700mm F7-8.8 MF ultra-telephoto zoom lens or a 300-1000mm F10-12.6 MF ultra-telephoto zoom lens respectively.
* The Pentax mount Tele Converter is not compatible with this particular lens.
