Category: Sigma
The Sigma 20‑200mm F3.5‑6.3 DG Contemporary is a versatile all‑in‑one zoom lens made for full‑frame mirrorless cameras (Sony E‑mount and L‑mount). It offers an ultra‑wide 20mm on the wide end to fairly strong 200mm telephoto on the long end — a 10× zoom range — allowing photographers to cover a huge variety of shooting scenarios with a single lens: sweeping landscapes, street, portraits, travel, wildlife, etc.
Despite this large zoom range, the lens aims to remain compact and portable for such power, with weather sealing (dust‑ & splash‑resistant), front element coating that’s water‑ & oil‑repellent, and optical corrections for aberrations, flare, and ghosting. It uses an HLA (High‑response Linear Actuator) motor for autofocus, making it reasonably fast and suitable even for moving subjects. There’s also a zoom‑lock switch to prevent “zoom creep” when carrying or when gravity might pull the lens to extend.
This lens is especially useful for photographers who prefer not to swap lenses constantly, or who travel and need both wide‑angle and telephoto in one kit. Of course some trade‑offs are there (variable aperture, maybe less optical “prime‑like” quality at extremes) but Sigma has packed a lot of features into this lens for its class.
