The Viltrox EF-EOS M2 0.71x adapter allows you to connect EF mount lenses to the Canon M body. The adapter supports full electrical communication between the lens and the body, so autofocus, among other things, works.
This adapter also works as a speedbooster, meaning it changes the focal length to 0.71x. This increases the lens's aperture by about one stop. In addition, the increase in focal length cancels out the effect of the crop factor, meaning a 50mm lens is still about 50mm even on APS-C sensor bodies.
The adapter has a detachable stand mount on the bottom and a USB port for updates.
