Product Information

product description

An ultra-telephoto zoom lens covering a telephoto range up to 500mm, incorporating Sigma’s original 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 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. 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 Optical Stabilizer technology
The lens is equipped with Sigma’s own unique 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.

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 Optical Stabilizer function provides stable images though the viewfinder and enables the photographer to easily determine the composition with the narrow angle of view.

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 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.

Hyper Sonic Motor
