The Redrock Micro LiveLens MFT is the first active lens adapter that enables Canon EF lenses to be used with any micro four-thirds (mft) camera, such as the Panasonic AG-AF100, Panasonic GH1/2 and Olympus Pen cameras. Canon EF lenses require power and electronic controls in order to adjust the lens' aperture. Without power and control electronics, The aperture of the EF lenses are stuck wide open, severely limiting the usefulness of the lens.
The Redrock LiveLens mft active lens adapter solves this problem by providing power to the EF lens and a control pad to adjust the lens aperture. With LiveLens mft you can set the EF lens' aperture to any stop in increments as small as 1/3 stop.
The Redrock Micro LiveLens mft is the solution for using sharp EF-mount lenses on Micro Four Third bodies without sacrifice. Where standard "dummy adapters" just physically mount EF lenses to the Micro Four Third body, the Redrock micro LiveLens MFT talks to the lens, giving you the ability to adjust your aperture without the need to use time consuming workarounds on set.
