Canon RF 100-400mm f/5.6-8 IS USM Lens

The Canon 5050C002 is an RF-mount telephoto zoom lens that stretches from 100 mm to 400 mm, giving photographers and videographers the reach they need for wildlife, field sports, airshows, and distant landscapes without the burden of a heavy rig. Designed specifically for Canon R-series cameras, it balances long focal lengths with a compact body that weighs about 1.4 pounds and measures roughly 6.5 inches, so you can keep it on your camera during a full day of shooting or pack it easily in a travel bag.

Inside, built-in optical image stabilization delivers up to six stops of correction, a major help when you are panning with fast action or hand-holding at dawn and dusk. The Nano USM drive focuses quickly and almost silently, a combination that suits both still photography and on-camera audio during video work.

The lens can focus as close as 2.9 feet and reaches 0.41× magnification at 400 mm, which means you can fill the frame with small birds, flowers, or details on a vehicle badge without changing lenses. One Ultra Low Dispersion element and one aspherical element work together to reduce chromatic aberrations and maintain sharpness across the zoom range, while a programmable control ring lets you dial in exposure or ISO directly from the lens barrel.

For even more reach, the 100-400 mm pairs with Canon RF 1.4× and 2× extenders, turning distant subjects into frame-filling shots. A standard 67 mm front thread accommodates polarizers or neutral-density filters, making it easier to manage glare or control shutter speed in bright conditions.

Whether you are tracking birds along a coastal trail, covering your child’s soccer match from the sidelines, or packing light for a safari, this lens offers a versatile blend of range, portability, and reliable autofocus that fits seamlessly into an RF system kit.
