Metabones EF to MFT Speedbooster

The Metabones EF to MFT Speedbooster allows you to connect EF lenses to MFT-mount cameras like the GH series (including the Panasonic GH4).  The adapter reduces the focal length by .71x, increases the aperture by one stop, and allows for electronic control, including aperture adjustments, image stabilization, and EXIF data.  Now, you can use the same lens kit for your EF cameras and MFT cameras.

For heavier lenses like CP2s and long zoom lenses, we strongly suggest using 15mm rails and a lens support.

This is a fantastic adapter for video, but some photo lenses may autofocus more slowly with the adapter.  Most EF-S and some lenses converted to EF may not work properly. Nearly all native EF lenses are supported, but please check the adapter when you pick up your rental to confirm that it will work for your purposes.
