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. It works with just about every lens available today, including variable aperture zoom lenses, prime lenses, consumer-level lenses, and professional L-series lenses. It also works with most third party EF-compatible lenses. There are some limitations to please make sure to read Technical Details.


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. Don’t work around the ability of your lenses; make your lenses work for you, starting today.

How does LiveLens mft work?
The LiveLens mft is a lens adapter that fits onto any micro four-thirds camera body, and provides a Canon EF lens mount on the other side for attaching any EF-compatible lens. an on board computer and electronics power a small control panel that allow you to adjust the aperture of the lens, open or closed, in 1/3 stop increments.


Does LiveLens do what I need it to do?
Absolutely. LiveLens technology has been used by many professional productions for over three years, demonstrating the reliability and capability of LiveLens. With a few exceptions it works with most EF-compatible lenses.LiveLens mft uses true active EF lens control technology, not fake extra iris, mechanical-only lens mount, or other non-performing poor quality "solutions" found on the Internet today.


How is it powered?
The LiveLens mft is powered by an external 9v battery, which can be switched on and off.


How long does the 9v battery last?
The 9V battery can power the unit for about 20 hours depending on how frequently aperture is adjusted .


Will this adapter work on all of my lenses?
The Redrock Micro LiveLens MFT will work on most Canon EF Lenses. However, there are a few exceptions. LiveLens mft does not power focus by wire lenses like the 85mm f/1.2 and 300mm f/2.8. It also does not work with Canon or third party teleconverters, extenders, or macro tubes.


How would I support long or heavy lenses?
If you plan on using long or heavy glass, we’d suggest a microLensSupport to ensure the lens is secure and properly supported.


Can I use the camera to control aperture?
Currently the lens aperture is controlled only through the LiveLens control pad, not the camera.


Do I need to change any setting in my camera before shooting with the LiveLens MFT?
Make sure that the Lens Check function of your AF100 is off. To do so, navigate in the AF100 to Menu > Other Functions > Lens Check > Off . You will see a black screen when your LiveLens MFT is attached if your lens check is enabled.


Will this power the image stabilizer of my IS enabled lenses?
Currently the LiveLens MFT powers only the aperture control of the lens, and does not provide power for image stabilization.


How does this differ from the LiveLens for the M3?
The underlying control technology of the LiveLens MFT and LiveLens for M3 is identical. Where the LiveLens MFT differs is it’s custom-built flange that attaches the unit to the Micro Four Thirds lens mount. LiveLens for the M3 has been proven to work for over three years in production environments and gives LiveLens mft this proven reliability.
