The Canon EF 100-400mm f/4.5-5.6L IS USM lens delivers high-resolution with superb contrast, neutral color balance, and built-in Optical Image Stabilization to compensate for blur caused by camera movement.
High zoom magnification is achieved by means of a 6-group configuration with 5 movable groups. Fluorite and Super UD glass reduce secondary spectrum for superb color rendition. Autofocus is fast and silent with Canon’s ring Ultrasonic Autofocus Motor (USM), and AF speed is further enhanced through an advanced, lightweight rear focusing design that incorporates a floating element for consistent image quality at all focusing distances from 5.9′ to infinity.
The dual-mode image stabilizer is suitable for panning shots, as well as stationary subjects. With full-time manual focus, one-touch zooming with a wide grip, a focus range limiter and a special ring that permits adjustment of zooming tension, this is a lens that’s extremely easy to use, and ideal for a wide variety of applications including nature, wildlife, sports, and documentary photography.
