Discover a blend of reach, speed, and professional image quality designed for the EOS R system. The Canon RF100-500mm F4.5-7.1 L IS USM is a compact, lightweight super telephoto zoom that delivers outstanding sharpness, reliable autofocus, and versatile performance—from fast sports to intimate wildlife moments and even dramatic aviation coverage. Built to Canon’s L-series standards, this lens brings exceptional resolving power, robust construction, and sophisticated stabilization to the RF lineup, empowering photographers to capture decisive moments with confidence and creativity.

• All-in-one telephoto range for fearless field shooting: The 100-500mm focal length covers a wide spectrum—from environmental portraits at 100mm to distant subjects at 500mm—allowing you to adapt quickly to changing scenes without swapping lenses. This flexibility is especially valuable on busy sidelines, in unpredictable wildlife behavior, or when chasing fast aircraft in the sky.
• Professional optical quality with weather-resistant build: As a true L-series lens, it delivers exceptional sharpness, contrast, and color fidelity across the frame. The optical design minimizes aberrations and distortion, ensuring image quality remains consistently high from corner to corner, even at the longest focal lengths. Coupled with weather sealing, it’s built for challenging outdoor environments, rain or shine.
• Fast, reliable focus with smooth, quiet operation: Equipped with USM autofocus for rapid, precise focusing and near-silent performance, this lens tracks motion smoothly—crucial for sports and wildlife where the action moves quickly. The autofocus system works in harmony with Canon EOS R bodies to deliver responsive performance in a variety of lighting conditions.
• Advanced image stabilization for crisp handheld shots: The RF100-500mm features Canon IS technology that helps stabilize your view and keep your images sharp. Expect solid performance in moderate to challenging light, enabling you to shoot at slower shutter speeds to freeze motion or create deliberate subject separation without a tripod in many scenarios.
• User-centric design for comfortable, expressive shooting: Designed with the RF ecosystem in mind, this lens includes a thoughtful Zoom Ring, a robust build, and intuitive handling that suits both stills and video work. The compact form factor for a telephoto zoom enhances balance on mirrorless bodies, making long shoots more comfortable and enjoyable, whether you’re perched in the stands, hidden in the woods, or tracking planes from a runway.

how to install Canon RF100-500mm F4.5-7.1 L IS USM

Mounting this lens to a Canon EOS R camera is straightforward. Follow these steps to ensure a secure setup and optimal performance:

• Turn off the camera before removing the existing lens or attaching the new lens to avoid sensor or electronics issues.
• Align the red dot on the lens mount with the corresponding mark on the camera body. Gently insert the lens into the mount.
• Rotate the lens until you hear or feel a soft click, indicating the lens is securely mounted. Do not force rotation beyond this point.
• Power on the camera and enable any lens-related settings such as IS/Correction features. If available, activate Coordinated IS for improved stabilization when using multiple IS systems together.
• Attach the lens hood if included to reduce glare and protect the front element in bright conditions. Ensure the lens hood is oriented correctly to avoid vignetting.
• Set the focal length to your initial shooting preference (e.g., 100mm for wider scenes or 500mm for distant subjects) and adjust focus manually or with AF as needed. For handheld work, enable IS and adjust shutter speed to suit motion and lighting conditions.
• When not in use, store the lens with the cap on and in a protective bag or pouch. Clean the front element with a microfiber cloth and avoid touching the glass with bare fingers.
