The Canon EOS Camera System is the most complete Single Lens Reflex (SLR) camera system in the world. Whether you are a beginner or advanced professional looking for a digital camera or 35mm film camera, the EOS System takes your photography to the next level. Amazing image quality and outstanding performance are just two of the many benefits photographers, from beginners to professionals, will experience with every interaction with a Canon EOS digital camera. Great images start with great Lenses and, in many ways, an SLR is defined by the quality, breadth and scope of its associated system of Lenses. For many, Canon EF/EF-S Lenses alone are reason enough to choose the EOS System. A unique blend of the world’s most advanced optical, microelectronic, and precision manufacturing technologies, the Lenses are perfected in Canon’s laboratories and proven in the field. Whatever you shoot, whatever your budget, there are Canon Lenses perfect for your needs. Most highly regarded among professional photographers, Canon L-series lenses are distinguished by a bold red ring around the outer barrel. What makes them truly distinctive performance is the result of sophisticated Canon technologies, such as Ultra-low Dispersion UD glass, Fluorite and Aspherical elements, and Super Spectra Multi Coating.
