Our Take On Canon EF 200-400mm

An exceptional feature of the Canon EF 200-400mm is its cutting-edge Image Stabilization mechanism. The mechanism comprises three distinct stabilization modes so that there can be maximum flexibility during shooting. You will like its advanced ring-type USM that helps in providing fast, noise-free as well as precise autofocus effectiveness, and full-time override of manual focus. It is weather-sealed, hence, you won�t have issues using it in harsh weather. There is a detachable spinning tripod collar for convenient use with a monopod or tripod. It works perfectly with full-frame Canon EF-mount DSLRs, and you can use it with APS-C models to get a corresponding focal length of between 320 and 640 millimeters.

You only need to flip the left-hand switch to immediately beef up your reach to 280-560mm or corresponding 448-896mm when using APS-C cameras. The extender is solidly built into the housing of the lens to provide enhanced imaging effectiveness and maintain weather sealing. Its constant f/4 maximum aperture is a plus, even when the teleconverter is not in a position, providing regular brightness all through the zoom range. When you engage the 1.4x teleconverter, the highest aperture stands at f/5.6. With the use of four ultra-low dispersion elements and one fluorite element, this lens guarantees the ultimate reduction of chromatic aberrations and color fringing.

Also, there are unique IS modes that help you to take the best shots at all times. The IS modes are panning-optimized mode, single-shot mode, and Image Stabilizer activation mode.
