From
Birger Engineering:
"Birger is coming out with a lens control system for EF mount lenses on the Panasonic AF100. Control for the iris, both auto and manual, will be from the camera. Continuous (video-style) auto-focus will be supported on most Canon "L-series" lenses. Power is provided by the camera for most lenses. Image stabilization is supported on "IS" lenses, and this feature can be turned on or off from the lens. Ships 14 February 2011. MSRP $700 for the adapter. Optional cinema-style remote control, available at additional cost, to be announced January 2011. Sign up for the "General News" email list to receive updated announcements. Photo below is a prototype on an engineering sample of the AF100, and a Canon EF 17-40mm f/4 lens."
