Description: This large aperture, standard zoom lens contains state-of-the-art enhancements, including the company’s own Optical Stabilization (OS), anti-shake technology that offers the use of shutter speeds approximately four stops slower than would otherwise be possible. Once again, only Sigma has made it possible for Pentax and Sony shooters to utilize an anti-shake system in either the lens or the camera body.
