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. * 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, the Optical Stabiliser (OS) function will not work with film SLR cameras except Nikon F6 and Canon EOS-1V.
