Canon EF 100-400mm f/4.5-5.6L IS II USM Lens

The Canon EF 100-400mm f/4.5-5.6L IS II USM is a professional-grade telephoto zoom lens designed for wildlife, sports, and aviation photography where reach and optical quality are paramount. The second-generation design adopts a push-pull zoom mechanism replaced by a more conventional rotating zoom ring, improving handling and reducing the risk of zoom creep in the field. Optical construction consists of 21 elements in 16 groups, incorporating one fluorite and four Ultra-Low Dispersion glass elements to control chromatic aberration and deliver high contrast across the zoom range. The four-stop Image Stabilizer offers three modes including a dedicated panning mode, and the ring-type Ultrasonic Motor provides fast, near-silent autofocus with full-time manual focus override. As an L-series lens, the barrel features dust and weather resistance throughout, with a fluorine coating on the front element to repel moisture and smudging. The lens accepts Canon’s 1.4x III and 2x III extenders for additional reach, and is compatible with RF-mount bodies via Canon’s EF-EOS R adapter series.
