Ideal for press, sports and nature photography, this compact extender increases the focal length of Canon L-series telephoto or telephoto zoom lens’ by a factor of 1.4x, with higher AF accuracy and improved communication between camera and lens.

Focal length extension for super-telephoto lenses

High-quality construction
Improved anti-reflection materials inside the lens-barrel and a coating around the outer edges of the lens elements reduce flare. Construction is resistant to dust and water, helping to maintain images quality.

Improved communication between lens and camera
A built in microprocessor provides accurate transfer of data from between the lens and camera delivering an improved performance in AF and metering.

Compatible with L-Series telephoto and telephoto zoom lenses
