    Sigma AF 35-135 mm f/ 3.5-4.5

    35–135mm · f/3.5–4.5

    Overview

    The Sigma AF 35-135 mm f/3.5-4.5 offers good center sharpness throughout the range and reaches beyond 135 mm at close focus, but has a curved focus plane and minor CA at the long end. Build includes a loose push-pull zoom and sticky rear coating; the macro mode button is awkwardly placed. Minimum focus distance is long (~1800 mm). It suits users needing a compact, sharp zoom for film or APS-C, but those requiring flat field or close focus should look elsewhere.
