Product Description

Canon’s RF 100‑500 mm F4.5‑7.1 IS USM is a high‑performance L‑series telephoto zoom engineered for wildlife, sports, and distant subjects. This 5× zoom covers 100 to 500 mm in a compact form (~1.37 kg without tripod collar), with solid build quality and dust/water sealing. Autofocus is driven by Canons Dual Nano USM motors for smooth, quick, and near‑silent performance, ideal for fast‑moving subjects. Optical finesse comes via Super UD and UD glass elements plus Air Sphere Coating and a heat‑shield layer to minimize flare and maintain consistency in hot environments. Image Stabilization inside the lens delivers up to 5 stops of shake reduction, boosted to 6 stops when paired with IBIS‑enabled EOS R bodies. A customizable control ring, zoom‑friction ring, removable tripod collar, and a filter‑threaded lens hood with sliding window add intuitive handling. It’s equally adept at dynamic wildlife shots or compressed-angle landscapes.
