The Canon RF 100-400mm f/5.6-8 IS USM is a versatile telephoto zoom lens that opens the door to wildlife, sports, and aviation photography without the size and weight traditionally associated with super-telephoto optics. Designed for the EOS R mirrorless system, this lens strikes an exceptional balance between performance and portability. Weighing just 635g, it is significantly lighter than its L-series counterparts, making it the perfect companion for photographers who hike, travel, or shoot handheld for extended periods. Despite its compact form, it delivers high image quality across the frame thanks to the inclusion of Ultra-Low Dispersion (UD) glass elements that control chromatic aberration.
Performance is driven by Canon’s Nano USM focus motor, which provides high-speed, accurate autofocus for tracking fast-moving subjects like birds in flight or athletes. This motor is also incredibly smooth and silent, making the lens a viable option for video work where audio capture is critical. To ensure sharp results at long focal lengths, the lens features a powerful Optical Image Stabilizer that provides up to 5.5 stops of shake correction (increasing to 6 stops when paired with an IBIS-equipped body like the EOS R6 or R5). Furthermore, it is fully compatible with the RF 1.4x and RF 2x Extenders, allowing users to reach effective focal lengths of up to 800mm.
