The SLR Hut Canon EF 300mm f/2.8L IS II USM telephoto lens is extremely light for its class, and the native Image Stabilization system offers up to four extra stops of performance. Sharper images, with less chromatic aberration, a result of its fluorite optics, and fluorine coating, which keeps smearing and imprint to a minimum, augment the physical aspects of this optimal piece of craftsmanship, exhibited in its super-telephoto focal length, fast aperture endowment - yielding exceptional image quality and clarity, in keeping with the Canon L-Series line.
