Canon EF 2.0x II

The Canon Extender EF 2x II (also known as Canon EF 2.0x II) is the teleconverter designed by Canon for EF lenses, here offered as RCE Foto guaranteed used gear. Solid construction, precise mounts and reliable performance have made it a benchmark for photographers seeking more reach without increasing the bulk of their photographic equipment and the telephoto used lens.

Compatible with a selection of Canon EF telephoto lenses (particularly from the L series), it doubles the focal length and entails a loss of about 2 stops of brightness. It maintains electronic communication for AF, metering and any stabilization; autofocus performance depends on the camera body and the resulting aperture. Recognized for its refined build and for delivering the best results when paired with fast, high‑quality super‑tele lenses.

Designed for nature, birdlife and sports, it also suits reportage and outdoor events when greater reach is needed in a light backpack. Perfect for those working with Canon EF who want to extend their kit without resorting to new super‑telephoto lenses. The selection of RCE Foto guaranteed used offers reliability and technical checks, to safely integrate a key accessory of the Canon system.
