The EF 200-400mm f/4L IS USM Extender 1.4x from Canon is a medium to super-telephoto distinguished by its unique optical design and fast performance. Featuring a 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 greater reach.Super telephoto zoom is designed for full-frame Canon EF-mount DSLRs, however can also be used with APS-C models where it provides a 320-640mm equivalent focal length.One fluorite element and four ultra-low dispersion elements are used to greatly reduce color fringing and chromatic aberrations in order to achieve greater clarity and color accuracy.An Optical Image Stabilizer helps to minimize the appearance of camera shake by up to four shutter speed stops to better enable working in low-light conditions and with slower shutter speeds. Three distinct IS modes are available: standard single-shot mode, a panning-optimized mode, and a mode that only activates the Image Stabilizer during the exposure.Focus Preset function is available to quickly recall a programmed focusing position.Removable rotating tripod collar is included and benefits working with the lens atop a tripod or monopod.Compatible with optional EF 1.4X and EF 2X teleconverters.
