Canon 2x EF Extender II (Teleconverter) (USED)

High-Performance Focal Length Doubler for Professional Telephoto Lenses

The Canon Extender EF 2x II is a premium teleconverter designed specifically to double the focal length of compatible L-series telephoto and telephoto zoom lenses. Ideal for sports, wildlife, and photojournalism, this optical extender allows photographers to instantly increase their reach without the burden of carrying additional heavy telephoto lenses. By maintaining communication between the lens and the camera body, it seamlessly integrates into a professional workflow, making it an essential tool for photographers who need maximum magnification while working in the field.

Advanced Optical Design for Maximum Image Clarity

Engineered to meet the rigorous demands of professional imaging, the Extender EF 2x II features an upgraded optical layout compared to its predecessor. It is constructed with high-index glass elements to minimize chromatic aberrations and distortion, ensuring that the sharpness and contrast of the master lens are preserved. The internal baffling and specialized anti-reflective lens coatings significantly reduce ghosting and flare, which are common challenges when introducing additional optical elements into a lens system.

Weather-Resistant Construction and Seamless System Integration

Built to withstand harsh outdoor environments, this teleconverter features a robust, weather-resistant construction complete with rubber seals at the mount joints to protect against dust and moisture. It fully supports the lens's autofocus (AF) tracking speed, image stabilization (IS), and E-TTL II flash metering when paired with compatible camera and lens combinations. Note that using a 2x extender results in a two-stop reduction in maximum aperture, so autofocus functionality depends on the maximum aperture of the master lens and the AF sensitivity of the camera body.
