This latest version of the Sigma APO 120-300mm F2.8 EX DG OS HSM is pleased to announce the inclusion of Optical Stablization(OS) which is critical to equipment sporting this focal range allowing for hand-held tele-photography and the use of shutter speeds approximately 4 stops slower than would otherwise be possible.
One SLD and two FLD glass elements provides maximum correction of chromatic aberrations.
The super multi-layer coating reduces flare and ghosting, and the lens design incorporates an inner focusing and inner zooming system to ensure sharp images throughout the entire zoom range.
