The Canon EF 100-400mm f/4.5-5.6L IS II USM lens offers a professional level telephoto zoom. Its flexible approach towards a range of photography opportunities is all down to its superlative handling and consistently high image quality, so its a great choice for capturing wildlife and sports. This lens is compatible with Extender EF 1.4x II and Extender EF 2x II. Super zoom An L-series telephoto super zoom lens, the Canon EF 100-400mm f/4.5-5.6L IS II USM comes equipped with a floating optical system which ensures that the picture quality is good at all focal lengths. Its versatile zoom range of 100-400mm makes it ideal for close-up and action shots. Ultrasonic focusing The autofocus is driven incredibly quickly and almost inaudibly thanks to the ring-type ultrasonic motor. With excellent holding torque, the point of focus will be reached accurately without risk of overshooting. You can adjust the focus yourself whilst still in AF mode with full-time manual override options. Image Stabilisation This lens is ideal for handheld photography thanks to its three stop Image Stabiliser (IS). You can use shutter speeds up to three stops slower than usual without any perceptible increase in blur in your images. If there is major movement in any one direction, the lens will interpret this as panning and will automatically turn off IS. High image quality Throughout the zoom range, low distortion, high contrast and good corner-to-corner resolution remains evident. An electromagnetically controlled, virtually circular aperture diaphragm gives regions which are out-of-focus a softer, more even feel, and makes in-focus subjects stand out against a blurred background.
