The new Canon EF to MFT Speed Booster is here!

Metabones released the new Canon EF to Micro-4/3 mount Speed Booster adapter. The adapter makes the lens 0.71x wider, increases maximum aperture by 1 stop, and also increases MTF. The adapter features built-in electronics to control lens aperture by the controls on the camera body, and is also powered by the camera's body. The adapter is an ideal companion for Blackmagic Cinema Camera MFT or the mirrorless Panasonic GH4 models.
