Sigma Introduces APO 120-300mm F2.8 EX DG OS HSM Zoom Lens

Sigma APO 120-300mm F2.8 EX DG OS HSM Zoom Lens

The new Sigma APO 120-300mm F2.8 EX DG OS HSM telephoto zoom lens promises improved optical performance over the previous version of this lens, which lacked the OS function. Sigma says the new lens provides excellent correction of sagittal coma flare and ensures ultra-high resolution, comparable to a fixed focal length lens.

This large aperture zoom lens features Sigma’s OS (Optical Stabilizer) function and weather-resistant design throughout for use in harsh conditions. The company says the lens’ OS function offers the use of shutter speeds approximately 4 stops slower than would otherwise be possible and enables hand held tele-photography.

One SLD and Two FLD glass elements are used for maximum correction of chromatic aberrations, Sigma adds. The Super Multi-Layer lens 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.
