Canon Extender EF 2x III brand_Thinktank Sporting not a zoom butCanon Extender EF 2x III teleconverter, in excellent cosmetic condition. Doubles the effective focal length of the lens mounted to it. Since the teleconverter extends into the back of the lens, not all lenses may be mounted: this works with select Canon L series telephoto lenses only. Please confirm compatibility between your intended lens and this teleconverter. Clean glass and excellent function.
