Canon Lens 2x Extender II

Canon Lens 2x Extender II

Canon EF Extenders are the ideal accessories for photographers who wish to increase the power and versatility of their existing lenses. EF Extenders work by increasing the distance between the film plane (or CCD) and the rear element of the lens. The extra distance increases the effective focal length of the lens to bring distant subjects closer. Canon EF Extenders are specially designed for many of Canon's large aperture EF lenses and retain all metering and AF functions with most of these.

This teleconverter is designed to Auto Focus with Canon L series Telephoto and Telephoto Zoom lenses with a maximum aperture of f/2.8 or faster. It will function with most L series Telephoto and Telephoto Zoom lenses with maximum apertures smaller than this but in Manual Focus only. For more information on teleconverter/lens compatibility please check Canon lens specifications.
