Canon RF‑S 55‑210mm F5‑7.1 IS STM – Lightweight APS‑C Telephoto Zoom

The Canon RF‑S 55‑210 mm F5‑7.1 IS STM is a compact and lightweight telephoto zoom lens made for Canon APS‑C sensor mirrorless cameras (RF mount). With a focal range equivalent to 88–336 mm (35 mm equivalent), this lens gives you significant reach for subjects that are far away — ideal for wildlife, sports, portraits, or travel. Despite its telephoto range, the lens remains portable — weighing only approx. 270 g l — making it easy to carry for long shoots or to throw into a travel bag. The lens features a 4.5-stop Optical Image Stabilizer to help reduce camera shake, and when used with an EOS R-series camera with in-body stabilization, it can achieve up to 7 stops of coordinated IS. Autofocus is driven by a lead-screw type STM (Stepping Motor), which provides smooth and near-silent focus — especially useful for video.The lens also includes a combined control + manual focus ring, allowing intuitive camera parameter control like ISO or exposure compensation. For creative depth of field, it has a 7-blade near-circular aperture, which helps produce pleasant bokeh. At the long end (210 mm), it offers a 0.28× maximum magnification, making it possible to shoot tighter detail while keeping distance.Optically, the lens uses 11 elements in 8 groups, including two UD (Ultra‑Low Dispersion) glass elements, which help minimize chromatic aberration and deliver sharper, cleaner images.
