Overview
  • 1Description

This Sigma 120-400mm f/4.5-5.6 DG APO OS HSM Autofocus Lens for Sigma SLR Camera is an ultra telephoto zoom lens ideal for nature/outdoor or sports photography. This translates into an equivalent range of 204-680mm when used with a Sigma digital SLR camera.

The use of HSM (Hyper Sonic Motor), APO apochromatic design, three elements of SLD (Special Low Dispersion) glass, and multicoated optics all enable this lens to provide a high level of performance throughout its entire zoom range, as well as versatility. A rear focus system insures quick, convenient manual focus and a non-rotating front barrel.

The improved DG lens design corrects for various aberrations. This lens is specially coated to get the best color balance, while cutting down on ghosting caused by reflections from the digital image sensor. The lens provides the utmost correction against lateral chromatic aberration, which is a serious problem for digital SLR cameras.

By adding the optional Sigma APO teleconverter, you can use this lens as a 168-560mm f/6.3-8 manual focus ultra-telephoto zoom lens with a 1.4X EX teleconverter, or as a 240-800mm f/9-11 manual focus ultra-telephoto zoom lens with a 2X teleconverter.

The HSM (Hyper Sonic Motor) system ensures quiet and high-speed auto focusing with full time manual focus override.
Three Special Low Dispersion (SLD) elements provide excellent correction for chromatic aberration.
Super Multi Layer (SML) coating reduces ghost and flare.
The lens design incorporates an inner focusing system, which prevents the front of the lens from rotating, thereby making it particularly suitable for use with circular polarizing filters and petal shaped lens hoods.
