This telephoto zoom lens incorporates Sigma’s original OS function and is housed in a compact construction. The OS function offers the use of shutter speeds approximately 4 stops slower than would otherwise be possible.

The Super Multi-Layer Coating reduces flare and ghosting and provides high contrast images throughout the focal range. This lens has a minimum focusing distance of 150cm (59.1”) throughout the entire zoom range and a maximum magnification ratio of 1:3.9, making it ideal for close-up photography.

• SIGMA’s own unique OS technology
  This 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. It makes telephoto shooting easy for many types of photography such as sport and nature. 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 mount, it is not possible to use AF and OS when attaching to a film SLR, Pentax ist* series and K100D DSLR cameras.
