Perfect for wildlife, sports, travel and more, the RF100-400mm F5.6-8 IS USM is a compact, lightweight telephoto lens for EOS R Series cameras, offering a versatile zoom range that brings subjects closer with ease. The RF100-400mm F5.6-8 IS USM is similar in size to the EF 70-300mm F4.5-5.6 IS II USM lens, and not only reaches to 400mm, but also has fast Nano USM focusing and up to 6 stops of Coordinated IS when used in combination with an EOS R series camera featuring In-body Image Stabilization, like the EOS R5 and EOS R6, or 5.5 stops with an EOS R/RP camera. Using a single Ultra Low Dispersion lens element towards the front of the lens group corrects chromatic aberration throughout the entire zoom range, making your images look crisp and colorful with minimal color blur. The RF100-400mm F5.6-8 IS USM lens can also accept both the RF1.4x and RF2x tele extenders giving you the effective maximum focal length of 560mm and 800mm respectively. With a control ring that allows for quick setting changes, including shutter speed and aperture, the RF100-400mm F5.6-8 IS USM lens puts quality, convenience and control in your hands.

• Compatible with Canon EOS R series cameras: For use with your existing camera with an RF mount system.
• Telephoto lens provides detailed photos from a distance: Magnify distant subjects and isolate a small field of view for vivid close-up shots.
• 100-400mm focal length: This versatile, long-range zoom lens covers a broad range, enabling you to capture the perfect image from various distances.
• f/5.6 maximum aperture: Provides clear landscape images and beautiful distance shots even in the shade and on cloudy days.
• Compact, lightweight and high-image quality RF telezoom lens, with a versatile zoom range of 100-400mm: The travel-friendly size and weight (similar in size to the EF 70-300mm F4.5-5.6 IS II USM lens but a bit lighter) of this lens makes it easier for it to be attached with a camera around your neck while walking around for an extended time and also allows room for more lenses in a camera backpack.
• Optical image stabilizer with up to 5.5 Stops* of shake correction: Because RF lenses are designed specifically for the RF Mount found on EOS R series cameras, the lens and camera combine to share Image Stabilization data, helping to dramatically reduce the effect of camera shake that can occur when working handheld. This applies when capturing both stills and video with up to 5.5 stops of stabilization* for accurate and clear content.
• Up to 6 stops of shake correction** when paired with EOS R Series cameras featuring In-Body Image Stabilizer (IBIS): This IS enabled lens can provide even more steadiness when shooting, up to 6 stops of coordinated IS, if paired with an EOS R Series camera featuring In-Body Image Stabilization, such as the EOS R5 and EOS R6, to further help you capture impressively clear results with slower shutter speeds.
• Minimum focusing distance of 2.89 feet at 200mm and maximum magnification of 0.41x at 400mm: The RF100-400mm F5.6-8 IS USM lens is capable of capturing sharp and detailed images from various distances. Especially noteworthy is the lens’s close-up capabilities at the 400mm zoom setting — at its minimum focus distance, at 400mm, you can fill the frame with a subject about the size of a credit card providing outstanding versatility and strikingly sharp images.
• High speed, smooth and quiet autofocus with Canon’s Nano USM: With any Canon EOS R-series camera, expect swift and positive autofocus. The Nano USM focus system is especially advantageous to video users, because of its combination of quiet operation and outstanding smoothness of focus changes during actual recording.
• 9-blade circular aperture for beautiful bokeh: Getting a smooth and natural looking out-of-focus background blur isn’t a problem for this lens as it has a 9-blade circular aperture which separates your subject from the background, while also providing a beautiful backdrop that's visually appealing in itself.
• Control Ring for direct setting changes: The RF100-400mm F5.6-8 IS USM lens incorporates a Control Ring on the lens barrel that can directly adjust numerous settings including shutter speed, aperture, ISO, exposure compensation and more. Located towards the front of the lens it effectively adds a third dial to EOS R and RP cameras, and a fourth dial to cameras such as EOS R5 and R6 cameras.
• Compatible with optional Canon Extenders RF1.4x^ and RF2x^^: To help get you even closer to the subject, attach the compatible optional Canon RF extenders to the RF100-400mm F5.6-8 IS USM and get the equivalent of 560mm focal length coverage with the Extender RF1.4x, or 800mm using the Extender RF2x.
