Canon EF Lens: The Heart of the EOS System

At the core of the EOS system, Canon's renowned EF lens series offers infinite choices and features for any project, and any budget. With over 50 lenses ranging from fish-eye to super-telephoto, with both fixed-length and zoom lenses to fit any photographer's needs, EF lenses have proven their worth in every photographic context.

Canon designs and manufacturers each of their lenses to provide high image quality throughout the entire image area, with natural background blur, and consistent color regardless of the lens chosen. All Canon EF lenses are designed to be quick, quiet, and highly reliable. With these priorities in mind, Canon's designs have remained on the cutting edge of technological innovation-if a technology does not exist, Canon invents it. Here's a closer look at some of the technologies that Canon has incorporated into their EF lenses.
