 Sigma APO 50-150mm F2.8 EX DC OS HSM lens : Sigma announces the new Sigma APO 50-150mm F2.8 EX DC OS HSM lens, designed especially for APS-C size image sensors. Sigma’s proprietary OS (Optical Stabilizer) system offers the use of shutter speeds approximately 4 stops slower than would otherwise be possible, enabling hand held tele-photography. The Sigma 50-150mm lens offers six SLD glass elements to compensate for chromatic aberrations and provide high image quality throughout the zoom range. The Super Multi-Layer Coating of the Sigma APO 50-150mm reduces flare and ghosting and ensures sharp and high contrast images even at the maximum apertures.
