Redrock announced the new LiveLens MFT’s control touchpad that allows the full control of EF lens aperture! The aperture ring can be open and closed in increments as small as 1/3 stop. (Imaging Resource). That is definitely a more advanced (but also much more expensive) solution than using the manual Kipon adpater (click here to see them on eBay).
P.S.: And Birger will also announce a new product soon (Maybe a new Eos to m43 adapter?).
