Sigma EF 70-200 f/2.8 EX-DG-APO-OS-HSM

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.
Optical Stabilizer system minimizes the appearance of camera shake to benefit making sharper imagery when shooting handheld.
