Sigma 70-200mm f2.8 EX DG OS HSM - Nikon Fit

Packed with the latest technology from Sigma and smaller than its predecessor, the Sigma 70-200mm f2.8 EX DG OS HSM lens features Optical Stabilisation (OS), which helps achieve blur-free shots even at maximum zoom, and a fast f/2.8 aperture that is ideal for shooting in low light. The HSM (Hyper Sonic Motor) offers quiet and high speed AF as well as full-time manual focus capability.

Key Features: Sigma 70-200mm f/2.8 EX DG OS HSM

• Designed for use with full frame digital SLR cameras. May also be used with smaller APS-c size sensors with a corresponding effective increase in focal length to about 100 to 300mm with most cameras
• Offers Sigma’s OS System (Optical Stabilization) allowing handheld photography even in low-light situation
• HSM (Hyper-Sonic Motor) ensures a quiet & high-speed auto focus
• FLD glass elements with performance equal to fluorite glass for compensate for colour aberration

Ideal for handheld photography
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 86.4mm(3.4in.), overall length of 197.6mm(7.8in.) and weight of 1,430g(50.4oz.). This compact and lightweight construction makes it ideal for many types of photography such as portraits, landscapes and sports.

Excellent Optical Performance
This lens features 2 FLD ("F" Low Dispersion) glass elements, which have the performance equal to fluorite glass, and 3 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.

Hyper Sonic Motor
The lens incorporates HSM (Hyper Sonic Motor), ensuring high speed and quiet AF as well as full time manual focus capability.

* For Sony and Pentax mount, AF will not function with DSLR cameras that do not support HSM.

Inner focusing and inner zooming system
The lens design incorporates an inner focusing and inner zooming systems. The overall length of the lens does not change during focusing and zooming, ensuring convenient handling. The inner focusing system also eliminates front lens rotation, making the lens particularly suitable for using circular polarizing filters and the supplied petal-type lens hood. A removable tripod collar (TS-21) is included as a standard component.

Rounded diaphragm
This lens has a rounded 9 blade diaphragm which creates an attractive bokeh to the out of focus area.

APO Tele-Converter (Optional)
The addition of the optical 1.4x EX DG APO or 2x EX DG APO Tele Converters* produce a 98-280mm F4 AF telephoto zoom lens or a 140-400mm F5.6 AF telephoto zoom lens respectively.

* The Pentax mount Tele Converter is not compatible with the particular lens.

Hood Adapter HA850-01 (Supplied)
Hood adapter extends the length of the lens hood and provides more effective shading when used with digital cameras with an APS-C size images sensor.

* When using the APS-C Hood Adapter HA850-01 with digital cameras with larger than APS-C size image sensor, vignetting will occur. Please remove the hood adapter if you are using these cameras.

Lens Terminology

DG
Sigma’s DG lenses are designed for cameras with a full-frame sensor, but cameras with a cropped sensor can also take these lenses. These are large-aperture lenses with wide angles and short minimum focusing distances. With an abundance of peripheral illumination, they are ideal lenses for Digital SLR Cameras whilst retaining suitability for traditional 35mm SLRs.

OS (Optical Stabilizer)
This function utilises a built-in mechanism that compensates for camera shake. It dramatically expands photographic possibilities by alleviating camera movement when shooting hand held.

EX
The exterior of this lens is EX-finished to denote the superior build and optical quality, and to enhance its appearance.
