Red Rock Microsystems has released this adapter we first suggested to them a few years ago. Now you can electronically control the aperture of your EF series Canon lenses while they're on your Micro 4/3 mount cameras. Function - Allows adjustment of the lens aperture in 1/3 stop increments.
Limitations - 1. Aperture control only through the control pad, not any camera controls - 2. Will not power image stabilization if your lens has it. - 3. Long or heavy lenses will require additional lens support. Power - Powered by an external 9v battery (included) that will last about 20 hours. Weight - Including 9v battery - 7.3 oz.
