Overview

The Sigma 70-200mm f/2.8 EX APO HSM is a professional-grade telephoto zoom lens engineered for Sigma SLR camera systems. Its constant f/2.8 maximum aperture provides consistent exposure control and shallow depth-of-field capability throughout the zoom range, making it well-suited for portraits with creamy bokeh, fast-moving sports subjects, and wildlife photography where light-gathering ability is essential. The APO (apochromatic) designation indicates the use of special low-dispersion glass elements that minimize chromatic aberration, resulting in sharper images with improved color fidelity.

The built-in Hyper Sonic Motor (HSM) drives the autofocus system quickly and quietly, an important feature when shooting in environments where noise is a concern, such as weddings or wildlife settings. As part of Sigma's EX professional line, the lens is built to a higher standard of construction and optical performance. The 70-200mm focal length is one of the most popular ranges for working photographers, providing enough reach to isolate subjects while remaining versatile enough for event and editorial work.
