|DG||The lens is designed for full-frame SLR cameras but can be also used on APS-C SLR cameras.|
|OS||The lens is equipped with optical image stabilizer. The stabilizer allows to increase the shutter speed by several stops and shoot handheld in such lighting conditions and at such focal lengths where without stabilizer you will have to use tripod, decrease the shutter speed and/or increase the ISO setting which can lead to blurry and noisy images.|
Sigma lenses for Olympus, Pentax and Sony digital SLR cameras are not equipped with optical image stabilizers because these cameras have built-in sensor-shift image stabilization technology.
|HSM||The lens is equipped with ultrasonic motor to provide very fast and virtually silent autofocus. Learn more|
|| S||Sports series of lenses which offers sophisticated optical performance and expressiveness. Delivers high action-capture performance enabling photographers to get exactly the shots they want.|

The lens barrel is large, heavy, dust-proof and water-resistant, made of high-quality plastic (TSC). The lens mount is metallic.
The lens features AF/MF focus mode switch.
|AF||Autofocus mode with Full-Time Manual Focus.|
|MF||Manual focus mode.|
The lens uses front filters with standard size of 105 mm which are easy to find. However, filters of such size are more expensive and mainly used with professional lenses.
The filter thread does not rotate during focusing which allows convenient use of different types of filters (including but not limited to polarizing and gradient).
Low dispersion elements (AD, ED, LD, HLD, SD, UD etc) and fluorite elements minimize chromatic aberrations and ensure excellent sharpness and contrast even at maximum aperture.
The lens features optical image stabilizer.
At the choice of the photographer the image stabilizer can operate in one of the following modes:
|Mode 1||Corrects vertical and horizontal camera shake. Mainly effective for shooting still subjects.|
|Mode 2||Corrects vertical camera shake during following shots in a horizontal direction.|
Typical Application1) Distant landscapes with perspective compression effect
2) On a tripod
