The Canon RF 100-300mm F2.8 L IS USM lens is a top-of-the-line offering for professional photographers and videographers seeking unparalleled zooming capabilities. It brings together the best of both worlds by combining the proven 300mm f/2.8 concept with advanced zooming features, delivering outstanding image quality and gorgeous bokeh that truly makes imagery stand out. This makes it ideal for capturing theater performances, event candid shots from a distance, and indoor sports such as swimming, gymnastics, and basketball.

High-performance Constant f/2.8 Max Aperture and Excellent Quality Lenses and Coatings

The Canon RF 100-300mm F2.8 L IS USM lens boasts an impressive set of features, including a high-performance constant f/2.8 maximum aperture throughout the zoom range. This allows for excellent low-light performance, fast shutter speeds, and incredible bokeh. Additionally, the lens offers exceptional optical quality, edge-to-edge, with an optical design that includes one fluorite lens, 4 UD glass elements, and Canon SSC to minimize ghosting and flare.

Optical Image Stabilization — up to 5.5 stops of shake correction

For consistently sharp results, its built-in optical image stabilization provides enhanced shake reduction for up to 5.5 stops of correction. When paired with an EOS R-series camera that has In Body Image Stabilization (IBIS), the Coordinated IS allows for up to 6 stops of correction. This means more reliable handheld performance and clearer detail in low-light situations, without having to increase the ISO or decrease the shutter speed.

Dual USM Focusing system with Control Ring for Direct Setting Changes

The Canon RF100-300mm F2.8 L IS USM lens also features a dual USM focusing system that offers incredible focus speed and accuracy throughout the entire focus range. This design even helps make the weight of the lens more balanced, reducing fatigue when held by hand. Additionally, a Control Ring on the lens barrel allows for direct setting changes, such as shutter speed, aperture, and exposure compensation, while function preset buttons located around the lens can be programmed to perform specific functions at the press of a button.

Just add Lightness, and Extra Reach

The RF 100-300mm F2.8 L IS USM lens is also incredibly lightweight, coming in at just under 6 lbs, making it easy to hand-hold for short periods of time. It even has a focus preset button for easy reach during use, allowing you to pre-focus on the spot where action is expected and immediately jump to the memorized position via the focus preset button. Furthermore, the lens is compatible with Extenders RF 1.4x or RF2x, which expand effective telephoto power to 140-420mm at f/4 or effective 200-600mm at f/5.6, respectively.

Dust and Weather-resistant Design, with Fluorine Coating on Front Element for Easy Cleaning

The Canon RF 100-300mm F2.8 L IS USM lens is built to L series lens specifications, with a highly durable design for excellent performance even in inclement weather conditions. It features a dust and water-resistant construction with seals around the mount, switches, rings, and more, and has a specially designed fluorine coating on its front surface to prevent water, oil, fingerprints, and other surface residue from sticking to the lens.
