A powerful addition to any serious photographer's arsenal, this compact extender is compatible with every fixed focal length L-series lens 135mm and over - as well as the EF 70-200/2.8L USM, EF 70-200/2.8L IS USM, EF 70-200/4L USM, EF 70-200/4L IS USM and 100-400/4.5-5.6L IS USM lenses.
It multiplies the lens' marked focal length 1.4 times, with a light loss of only one stop. Most impressively, its superior optics preserve the lens' inherent image quality. New with the version II extender are improved internal anti-reflective blackening, and enhanced weather resistance.
