Canon EF 70-200mm F/2.8 L IS USM Lens (USED)

The Canon EF 70-200mm f/2.8 L IS USM lens is a workhorse professional level large aperture telephoto zoom lens featuring innovative Image Stabilization technology.

Being an L series lens maximum attention was been given to sharpness, color reproduction, & bokeh by the designers. The heart of the lens is an optical system consisting of 23 elements in 18 groups; Four Ultra Low Dispersion UD glass elements are strategically placed to maximize image quality. A large f/2.8 maximum aperture allows superior light gathering capability, 8 aperture blades produce circular apertures for pleasing out of focus areas. All lens elements are free of lead.

Canon's optical Image Stabilization system consists of sensors which detect shake or vibration and a special set of elements moved in real time to offset the path of light to compensate for the lens shake. The Image Stabilization movement mechanism in the EF 70-200mm f/2.8 L IS USM is an upgraded design from earlier Canon IS lenses enabling smoother movements allowing up to three stops worth of stabilization. This means a photographer previously using a shutter speed of 1/500 of a second may now be able to get similar stability at 1/60th of a second. The image Image Stabilization system has two modes: Mode One designed for stationary subject matter and Mode Two designed for panning along with a moving subject. An On/Off button is also provided to save power and for when the lens is mounted on a solid support like a sturdy tripod.

Portrait Photographers, sports photographers, pet photographers, wedding photographers, photojournalists, wildlife photographer, other action photographers and nearly everyone else wants fast autofocus and Canon delivers it with an internal focus system connected to a ring type Ultrasonic Motor. The focus mechanism is designed to provide the photographer the option of instant manual focus override without touching the lens AF control button, manual focus override works full time (even without power to the lens). The zoom and focus grips have different patterns and widths to aid tactile differentiation. A focus limit switch allows selection of a narrower 1.5 meters to infinity focus range to significantly reduce autofocus time as closer focusing distances occupy an amount of focus travel that is proportionally much greater than in farther focus distances. The full focus range of the lens is 1.4 meters to infinity.

A removable tripod mount is standard equipment and it rotates for easier vertical photography on a tripod or monopod. The lens mount features a partial environmental seal mainly to aid reducing dust accumulation on digital sensors.
