TheCanon EF 200 mm f/2 L IS USM features a large aperture of f/2 and was specially designed to provide high image brightness for shooting indoor sport and for portrait photography.
As compared with the EF200mm f/1.8L USM, the new lens is equipped with a fluorite glass element for effective minimization of chromatic aberrations, and circular aperture. Thanks to a compact design, the lens has become lighter.
When the camera is being mounted on a tripod, the image stabilizer automatically shuts down, thus preventing feedback loops between the IS sensor and stabilizer motor vibrations. When shooting static subjects, Mode 1 compensates for vertical and horizontal image motions. During following shots in a horizontal direction, Mode 2 switches off vertical compensation, preventing a rolling shutter effect.
Thanks to UD and fluorite glass elements, the lens provides an unexcelled image quality identical with that produced by autonomous lenses or lenses with the Canon 1.4x extender.
There is an autofocus stop button on the black ring near the front element of the lens that allows autofocusing to be temporally switched off. The button can be preset to control autofocusing mode, image stabilization, auto-exposure lock on EOS 40D, EOS 5D, EOS-1D Mark III and EOS-1Ds Mark III cameras.
The EF200mm f/2L IS USM lens features a focus preset function for advance storage of focusing positions in memory to allow instantaneous focusing. This function may be useful for photographers shooting sportive events and wildlife.
