RF 70-200mm f/4 L IS USM

The Canon RF 70-200mm f/4 L IS USM is a versatile telephoto zoom lens designed for Canon's full-frame RF-mount mirrorless cameras. The lens maintains a constant f/4 maximum aperture throughout its zoom range while achieving a compact, lightweight design of just 1.5 pounds. It incorporates four ultralow dispersion elements to minimize chromatic aberrations, an air sphere coating to reduce flare and ghosting, and a protective fluorine coating on the front and rear elements for durability and ease of cleaning.

The optical image stabilizer provides up to five stops of shake correction, or up to 7.5 stops when paired with compatible EOS R bodies featuring in-body image stabilization. Its dual nano USM focusing system delivers fast, nearly silent autofocus with full-time manual focus override, and a configurable control ring allows quick adjustment of exposure settings including aperture, ISO, and exposure compensation. As part of Canon's L-series, the lens features a weather-sealed construction to protect against dust and moisture.
