Viltrox EF‑EOS M2 is a 0.71× electronic Speed Booster for Canon EF lenses on Canon EOS M cameras. It widens the field of view, increases effective brightness and retains autofocus and aperture control.

The 0.71× reducer optics provide a wider field of view and approximately one stop of additional effective brightness.
Focal length is multiplied by a factor of 0.71 after mounting.
The electronic adapter supports AF with compatible lenses and cameras.
Contacts enable aperture control and operating-data transmission.
The Speed Booster concentrates the Canon EF lens image circle onto an EOS M sensor.


The USB interface enables firmware updates, while a 1/4-inch thread aids stable mounting.
