EF 300mm f/2.8L IS II USM
The EF 300mm f/2.8L IS II USM has an obvious weight advantage over its predecessor. The lens has fluorite elements to reduce chromatic aberrations and fluorine coating to ensure that smears and dirt dont cling on to the lens front element. An advanced Image Stabilization system allows four stops of image-shake correction while a third IS mode which activates when the shutter is fully pressed is also provided.
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.
