Canon Extender EF 2x II Converter

The Canon Extender EF 2x II Converter is affordable and easy to use. The Canon EF 2x II provides outstanding optical performance that visually matches the images quality of the host lens.

The Canon Extender EF 2x II doubles the focal length of lenses it’s mounted to, and reduces its f stop aperture by 2 stops. All of these improvements in the Canon EF 2x II will allow professional photographers of capture higher quality images than ever before.

This Extender has been re-designed optically and offers excellent performance with compatible EF lenses. The Canon EF 2x II features a new seven-element design, and same weather-resistant design and anti-reflection internal construction as the new EF 1.4x II. The EF 2x II doubles the focal length of any lens it's mounted to, and reduces its effective aperture by two stops. With Canon EF 2x II, AF is possible with any EOS body if the lens has an f/2.8 or faster maximum aperture, and compatible Image Stabilization lenses maintain the IS feature when used with any current EOS camera.

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 2x II are specially designed for many of Canon's large aperture EF lenses and retain all metering and AF functions with most of these.

The Canon EF 2x II extender is an easy and very affordable way to dramatically extend the focal length of compatible canon L series lenses. The Canon EF 2x II Extender mounts between the compatible lens and body then multiplies the focal length settings of lens by 2. A canon EF 300mm f/2.8 L IS lens becomes a 600mm f/5.6 IS lens.

The canon EF 2x II Extender is relatively small and light. It is weather sealed when used with similarly-sealed lenses and camera bodies. This extender has been re-designed optically and offers excellent performance with compatible EF lenses.
