Canon RF 100-400mm f/5.6-8 IS USM
Integrating one fluorite and one Super UD element with Air Sphere Coating, this lens delivers sharp, high-contrast images with minimal aberrations, supported by a 4-stop Image Stabilizer for handheld clarity. A rotating zoom ring with adjustable torque and comprehensive weather sealing with a fluorine coating set it apart for reliable, precise control in tough conditions. It’s best for wildlife and sports photographers who need a rugged, stabilized telephoto zoom for tracking fast-moving subjects from a distance.
