Canon EF-M Lens Adapter Kit for Canon EF / EF-S Lenses

The Canon EF-M Lens Adapter Kit for Canon EF / EF-S Lenses is an official Canon mount adapter that lets photographers mount Canon EF and EF-S lenses, as well as TS-E and MP-E lenses, onto Canon EOS M-series mirrorless cameras, which use the EF-M lens mount. It’s designed as the key to unlocking the vast array of existing Canon lenses for use on an EOS M body, giving photographers access to a much broader lens selection than the EF-M native lineup alone.

The adapter is fully compatible with all lens functions, including autofocus and image stabilization, maintaining full electronic communication between the lens and camera body just as it would when the lens is mounted directly to an EF-mount body. It contains no optical elements, functioning purely as a mechanical and electronic pass-through, with its only moving part being the lens release switch, so it introduces no image quality degradation or change in effective focal length.

A detachable tripod adapter is included, providing additional support for longer, heavier Canon lenses and allowing the camera balance to be shifted rearward when tripod-mounted, since EOS M bodies are otherwise quite light. Build quality is solid metal construction, and the adapter itself weighs approximately 105-110g (3.7-3.9 oz.) and measures roughly 2.6-2.7 x 1.1-1.2 inches without the tripod adapter attached, adding a modest amount of additional length and weight when the tripod adapter is in place.
