Sigma 120-300mm f/2.8 DG OS APO HSM Lens for Canon EF

The Sigma 120-300mm f/2.8 EX DG OS APO HSM is delivers high speed superior optical performance for Full Frame or APS-C sized sensors. It features a Hyper Sonic Motor (HSM), an Optical Stabilizer, Inner Focusing and Zooming System, as well as SLD and FLD Glass Elements (FLD has a performance equal to fluorite). The HSM ensures quiet, high speed, accurate autofocusing while the OS allows for use of shutter speeds 4 stops slower than would otherwise be possible. Super Multi-Layer coating and the SLD and FLD lens elements work together to reduce flare, and ghosting while providing the maximum correction of chromatic aberrations. An inner focusing and zooming system produces sharper images throughout the entire zoom range, and the large fixed aperture of f/2.8 is capable of handling any lighting scenario. All of these amazing features make Sigma 120-300mm f/2.8 DG OS APO HSM Lens For Nikon the perfect lens for capture fast moving objects at a distance, perfect for sports and wildlife photography.

Apochromatic

In order to attain the highest quality images, the APO lens has been made using special low-dispersion (SLD) glass and is designed to minimize color aberration.

Teleconverter Compatible

This lens can be used with the APO Teleconverter EX. It can increase the focal length and will interface with the camera's AE (automatic exposure) function.

DG for Digital

Sigma's DG lenses are specifically designed to deliver the ultimate level of performance on full frame digital SLRs. Sigma DGs also maximize the abilities of 35mm SLR cameras and APS-C size DSLRs. Thanks to a complete and comprehensive approach to the correction of chromatic aberrations, you will experience incredible image clarity and smoothness. Specific attention was paid to helping eliminate color fringing often caused by lateral chromatic aberration, a problem that is magnified at high resolution in digital photography. DG lenses provide exceptionally high contrast along with subtle gradations in tone and color. Super Multi-Layer Coating, along with Sigma's optimized optical design work to reduce reflections between the image sensor and the lens surfaces. The large image circles of DG lenses mean there will always be enough peripheral illumination to avoid vignetting.

Quiet and Fast Autofocusing

HSM lenses employ a motor powered by ultrasonic waves that produce a quiet, yet high-speed AutoFocus. You can enjoy high performance with low noise in a variety of shooting situations.

Inner Focus

To ensure stability in focusing, this lens moves the inner lens group without changing the lens’ physical length.

Optical Stabilizer

This function utilizes a built-in mechanism that compensates for camera shake. It dramatically expands photographic possibilities by alleviating cameras movement when shooting by hand held camera.

Sport Lens

Engineered for dynamic capture and split-second timing, Sigma's Sports line delivers sophisticated optical performance to get you closer to those powerful action shots you're after.

Fixed Focal Aperture

Offering excellent image expression and a low F-number, the large-aperture 300 mm F2.8 lens is a favorite piece of equipment among professional photographers. While taking this spec to the next level with powerful zoom capability, SIGMA has also used two lens elements made of fluorite-equivalent FLD (“F” Low Dispersion) glass and one element made of SLD (Special Low Dispersion) glass, which help minimize chromatic aberration and provide image quality that rivals that of a fixed-focus lens.
