New Sigma APO 50-500mm F4.5-6.3 DG OS HSM. This is a 10x high zoom ratio ultra telephoto zoom lens incorporating Sigma's original Optical Stabilizer function. This lens covers a wide range of focal lengths from 50mm to 500mm ultra telephoto. The OS (Optical Stabilizer) function offers the use of shutter speeds approximately 4 stops slower than would otherwise be possible. Four SLD (Special Low Dispersion) glass elements provide excellent correction of color aberration. The Super Multi-Layer Coating reduces flare and ghost and ensures high image quality throughout the entire zoom range.
