Canon’s EF 200-400mm f/4L IS USM Extender 1.4x is a long-range zoom that offers versatility. Canon’s EF 200-400mm f/4L IS USM Extender 1.4x is a medium to super-telephoto lens with a unique optical design and fast performance. With the built-in 1.4x extender, you can quickly and intuitively switch between the native 200-400mm f/4 setting and an effective 280-560mm f/5.6 for a longer range. This unique design benefits from an advanced optical layout that includes a fluorite element and four ultra-low dispersion elements to control chromatic aberration and color fringing for clarity. The individual elements have also been given a super-spectral coating to reduce stray light and ghosting for improved colour accuracy and contrast when working in bright or backlit conditions.In addition to its optical characteristics, this 200-400mm f/4 also features an advanced four-aperture image stabilisation system with three separate stabilisation modes to suit different shooting applications. Handling is also enhanced by an advanced ring USM that provides fast, quiet and precise autofocus performance along with full-time manual focus override. In addition, this lens is weatherproof for use in harsh environments and features a removable, rotatable tripod cuff that makes it easy to work on a tripod or monopod.
