A worthy successor to the popular Canon EF 300mm f/2.8 IS, the all-new Canon EF 300mm f/2.8 IS II USM super telephoto lens is lightweight, weighing approximately 13% less than its predecessor, yet offers faster operation, improved image stabilization and superior optics. Incorporating Fluorite elements for improved image quality and reduced chromatic aberration plus a number of advanced coatings to minimize ghosting, flaring, and with a newly developed Fluorine coating that keeps soiling, smears and fingerprints to a minimum, the EF 300mm f/2.8 IS II USM is ready to deliver spectacular images in an instant. With a third Image Stabilization mode (Mode 3) that activates IS only when the shutter button is fully pressed, and giving the equivalent effect of a shutter speed four stops faster, the EF 300mm f/2.8 IS II USM allows for easy panning and is ideally positioned for professional action photography. The EF 300mm f/2.8 IS II USM also features a new security slot for wire-type security locks.
