SIGMA 70-200MM LENS NIKON F/2.8 LRG TELEPHOTOFrom the Manufacturer



Large aperture telephoto zoom lens incorporating Sigma''s original Optical Stabilizer function

This large aperture telephoto zoom lens, incorporating Sigma''s original Optical Stabilizer function, covers focal lengths from 70mm to 200mm and offers a constant aperture of F2.8 over the entire zoom range. The OS function offers the use of shutter speeds approximately 4 stops slower than would otherwise be possible. It makes shooting easy for many types of photography such as portraits and sports. Two FLD (''F'' Low Dispersion) glass elements, which have performance equal to fluorite glass, and three SLD (Special Low Dispersion) glass elements provide excellent correction of color aberration. Super Multi-Layer Coating reduces flare and ghosting. The lens incorporates HSM (Hyper Sonic Motor), ensuring a quiet and high speed AF as well as full-time manual focus capability. It is also possible to attach Sigma''s optional APO Tele Converters.No Optical Stabilizer (top). With Optical Stabilizer (bottom).Super Multi-Layer Coating

The lens is equipped with Sigma''s own unique OS (Optical Stabilizer) 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.

* For Pentax and Sony mounts, it is not possible to use the AF and the built-in OS function of this lens when attaching it to film SLR cameras as well as Pentax ist series and K100D.

* When using the OS function of a lens with a camera which incorporates a stabilizer unit, please turn the camera''s stabilizer unit off.

* This lens cannot be used with film SLR cameras with the exception of the Nikon F6 and Canon EOS-1v. Compact construction

This lens has a compact construction with a diameter of 3.4in, overall length of 7.8in. and weight of 50.4oz. This compact and lightweight construction makes it ideal for many types of photography such as portraits, landscapes and sports.No Super Multi-Layer Coating (left). With Super Multi-Layer Coating (right).Excellent Optical Performance

This lens features two FLD (''F'' Low Dispersion) glass elements, which have the performance equal to fluorite glass, and three SLD (Special Low Dispersion) glass elements providing excellent correction of color aberration. The Super Multi-Layer Coating reduces flare and ghosting and ensures high contrast images. High image quality is assured throughout the entire zoom range.

* FLD glass is the highest level low dispersion glass available with extremely high light transmission. This optical glass has a performance equal to fluorite glass which has a low refractive index and low dispersion compared to current optical glass. It also benefits from high anomalous dispersion.

These characteristics give excellent correction for residual chromatic aberration (secondary spectrum) which cannot be corrected by ordinary optical glass and ensures high definition and high contrast images.Hy
