Canon RF Mount. The Canon RF 70-200mm f/4L IS USM belongs to Canon’s line of RF-mount lenses. It’s compatible with RF cameras, such as the EOS R5, EOS R6, EOS R, EOS Ra, and EOS RP. It does not work with Canon EF-mount cameras.

Versatile Telephoto Zoom. This lens’s focal length covers a portrait to short-tele focal range, making it perfect for sports shooters and event photographers. The f/4 aperture range isn’t useful for low-light shooting, so you’ll probably want to stick with outdoor lighting conditions for best results.

Optical Image Stabilization. The built-in optical image stabilization system provides up to five stops of correction, allowing you to shoot in lower light and at lower shutter speeds without worry. When working with select cameras, the Coordinated Optical Images Stabilizer and the In-Body Image Stabilizer will combine to give you up to 7.5 stops of stabilization.

Dual Nano Autofocus. The Dual Nano autofocus system uses both a ring-type USM and an STM mechanism to ensure fast, accurate, and nearly silent autofocus performance. You also get full-time manual focusing when you’re working in one-shot AF mode.

Advanced Optical Design. This lens’s eleven-group/sixteen-element optical design includes four Ultra-Low Dispersion elements that reduce aberrations, color fringing, and distortion for maximum clarity, color accuracy, sharpness, and rendering. Canon has applied an Air Sphere Coating to each lens element to combat backlit ghosting and flaring while keeping contrast high.

Customizable Control Ring. You can configure the RF 70-200’s customizable control ring to adjust a variety of exposure settings, such as aperture, ISO, and exposure compensation.

High-Quality Build. This lens boasts a weather-resistant build that protects against the elements so you can use it in adverse conditions.
