The Redrock Micro LiveLens MFT Active Lens Mount is the first active lens adapter allowing Canon EF lenses to be used with any micro 4/3 (MFT) camera, including the Panasonic AG-AF100, Panasonic GH 1/2, and Olympus PEN cameras. A 9V battery and power cable are included.
Canon EF lenses need power and electronic controls to adjust aperture. Without them, aperture is stuck wide open, severely limiting the usefulness of the lens. The Redrock LiveLens MFT presents a solution to the problem, delivering power to the EF lens and a control pad enabling aperture adjustment. Using the LiveLens MFT, you are able to set the EF lens aperture to any stop in increments as small as 1/3 or 1/5, depending upon the lens. The adapter is compatible with virtually every EF lens on the market today, including variable aperture zoom, prime, consumer-level and professional L-series lenses. It also works with the majority of third party EF-compatible lenses.
Whereas standard "dummy adapters" only physically mount EF lenses to the Micro Four Thirds body, the LiveLens MFT communicates with the lens, giving you the power to adjust aperture without using time-consuming workarounds on set.
Works with most Canon EF lenses including third party....Does NOT work with Canon's 85mm 1.2.
