17–35mm · f/2.8–4
The Sigma 17-35mm f/2.8-4 EX DG HSM is a well-built wide-angle zoom with improved optics over its predecessor. It offers excellent sharpness and very low distortion, though performance drops at longer focal lengths due to the variable aperture. Close-up capability is a standout feature. Build quality is solid with a sleek matte finish, HSM focusing, and a useful depth-of-field scale. It suits photographers seeking an affordable, versatile ultrawide zoom for full-frame or APS-C, especially those prioritizing close-ups and low distortion.
