The Sigma 70-300mm f/4-5.6 DG OS Telephoto Zoom makes telephoto shooting easy for many types of photography such as sport and nature. The lens is built with Special Low Dispersion Glass (SLD) elements to provide corrections for all types of aberrations. Its super-multi-layer coating adds to the excellence of images by reducing flare and ghosting, yielding high contrast images throughout the focal range.
Sigma's OS (Optical Stabilizer) can reduce shutter speeds approximately 4 stops slower than would otherwise be possible. This lens rounded 9-blade diaphragm creates an attractive blur for out-of-focus areas of a picture. With a minimum focusing distance of 59.1" throughout the entire zoom range and a maximum magnification ratio of 1:3.9, this zoom is a good choice for close-up imaging. The compact construction of the lens helps make it good for travel and hand-held telephoto photography.
