This Accelerator Lens Adapter for Canon EF-Mount Lenses to Micro Four Thirds Mount Cameras from Vello allows a full-frame Canon EF-mount lens to be used on a Micro Four Thirds mount camera. The adapter's optics help to maximize the connected lens's angle of view while providing a one-stop increase for the camera over the lens's aperture range. When used with a Panasonic Micro Four Thirds mount camera or camcorder, this adapter's integrated, aperture toggle dial provides clickless stop adjustments that help prevent unwanted noise or vibrations from being recorded while capturing video with sound.
