Digital Camera World Verdict

The Canon RF 100-500mm is a superb addition to the rapidly expanding range of RF-mount lenses for Canon's EOS R-series cameras. It combines Canon's legendary L-series build quality with premium optical performance that's up there with the very best Canon zoom lenses we've tested. The only real drawback (apart from the hefty price tag) is you’ll need to shoot with this lens mounted on an EOS R5 or R6 to get the fastest AF performance.

The Canon RF 100-500mm f/4.5-7.1L IS USM is the first super-telephoto zoom lens for EOS R-system mirrorless cameras. It goes without saying this is a high-quality lens with its L-series build, and even has a heat shield coating for coping with shooting in challenging weather conditions, whether it’s hot or cold. Plus its 5-stop image stabilization will help you deliver sharp shots when shooting handheld with slower shutter speeds and in low light.
