Optimized for Canon digital SLR cameras, the Sigma 300m telephoto lens is a terrific choice for long-distance photography. The Sigma lens relies on two extra-low-dispersion (ELD) glass elements, which combine to reduce chromatic aberration and create sharp, high-contrast images. The multilayer lens coating, meanwhile, reduces internal reflection and minimizes flare and ghosting to further improve image clarity. Finally, the lens includes a built-in Hyper Sonic Motor (HSM) for quick and silent autofocusing, with a full-time manual override for people who prefer more autonomy. The 300mm lens--which is compatible with APO teleconverters (sold separately) for conversion to a 420mm or 600mm lens--also offers a drop-in 46mm filter holder in the rear part of the lens barrel. All Sigma lenses carry a one-year warranty. Specifications
