Renowned for its versatility, the Sigma SA-mount APO 70-200mm f/2.8 EX DG OS HSM from Sigma is a telephoto zoom lens covering a useful portrait-length to medium telephoto range. Characterized by its bright f/2.8 constant maximum aperture, this lens excels in difficult lighting conditions and also affords flexible depth of field control for isolating focus. Featuring an apochromatic designation, this lens's optical design employs a series of low dispersion elements to virtually eliminate chromatic aberrations and color fringing for high clarity and color accuracy. A multi-layer coating is also used to control ghosting and flare for improved contrast when working in bright and backlit conditions.
Balancing the optics, a Hyper Sonic Motor affords quick and quiet autofocus performance while an Optical Stabilizer minimizes the appearance of camera shake for sharper handheld shooting. Additionally, a removable, rotating tripod collar is included to better support working with the lens atop a tripod or monopod.
