Canon Extender EF 1.4x III & Canon Extender EF 2x III
The two new EF extenders are direct replacements of the current extenders offered by Canon as essential accessories for professionals. These new extenders have been designed to provide faster autofocusing and improved autofocus precision with compatible EF lenses. Each extender includes an anomalous dispersion lens element for reduced chromatic aberration and enhanced optical image quality. Each extender also features a newly developed microcomputer that increases AF precision when the extenders are used with a IS Series II EF super-telephoto lens. Both extenders are equipped with rubber gaskets and seals to enhance weather resistance. A new fluorine anti-smear coating is applied to the front and rear elements of both extenders.
The Canon Extender EF 1.4x III & Canon Extender EF 2x III are expected to be available in December for an approximate retail price of $500US each.
