    Mounts Canon EOS Lenses to Micro Four Thirds (MFT)

    Whether you're shooting digitally or on film, Fotodiox offers the world's largest selection of lens adapters. Mix camera/lens platforms or reinvigorate vintage glass; Fotodiox has hundreds of ways to mount lenses onto your DSLR or MILC camera. Our adapters deliver infinity focus and a sturdy build for lasting quality.

    The adapter is designed to offer an inexpensive system that allows for the use of a vast range of lenses. All Canon EOS EF  lenses produce image circles large enough to cover the Micro 4/3 sensor (though their performance will only have been optimized for their native formats). This adapter system is particularly useful for mounting tilt/shift and other specialty lenses not available in the native Micro-4/3 format to almost the entire range of MFT cameras, providing for an inexpensive alternative for photographers and videographers alike.

    Built-In FUSION Technology

    Sometimes you need more than a simple adapter to mount a lens onto a camera - you need real power. Seize control over the electronic features of your lenses with a FUSION lens adapter. The FUSION technology built into the adapter enables electronic communication between mixed lens and camera platforms. FUSION adapters enable auto focus, aperture control, image stabilization, and more. This adapter enables EXIF and aperture data to be transmitted to and controlled by the camera. Different lenses may exhibit different operating characteristics depending on lens age and manufacturer. We recommend testing individual lenses in your setup before critical shoots.

    Included on the adapter is a 'Iris Toggle' switch supports aperture control through the adapter. You can adjust the aperture from the adapter to directly control the lens actual aperture. Although the adapter will allow you to mount any Canon EF lens, not all lenses will perform the same. Lens firmware, focusing motors, and age of lens will all affect the speed, reliability and accuracy of the adapter.

    The EF-MFT Fusion Smart AF Lens Adapter is one of the first adapters in Fotodiox's Fusion line to include a micro USB port to allow for firmware updates providing a nearly future proof solution for MFT users by including new lenses and fixing possible bugs through firmware updates. For firmware updates and directions, please see the firmware update article for this adapter in the Fotodiox technical suppport knowledge base.

    Built in Focal Reducer

    A focal reducer is a little piece of magic between two lens mounts. The built in focal reducer refocuses the lens image circle which reduces the crop factor and amplifies the incoming light allowing for a smaller aperture needed. The adapter has an image angle magnification of 0.71x, which means that a lens with a focal length of 50mm has a focal length of 35mm. By concentrating the light in this way, the adapter also increases the light collection ability by about one stop, so that an aperture of f/1.2 instead becomes f/0.9.

    Natalie V. ★★★★★

    The focal reducer in this adapter gives my old Canon lenses a noticeably wider field of view on my Lumix body, and autofocus is snappy enough for casual shooting. I'm impressed the build quality feels solid despite the reasonable price.

    Victoria U. ★★★★★

    I’ve been using this adapter with my Canon 50mm f/1.4 on an Olympus body, and the autofocus is surprisingly snappy for stills. The built-in focal reducer gives me an extra stop of light, which really helps in low-light shots—definitely worth the upgrade over my old dumb adapter.

    Julian Y. ★★★★★

    Was a bit skeptical about the focal reducer’s effect on image quality, but the built-in FUSIO optics actually give my old Canon EF lenses a noticeably wider field of view on the MFT body. Autofocus locks quickly enough for most of my street shots, and the full electronic aperture control works witho
