Have you looked into Fotodiox's adapter? (http://www.amazon.com/Fotodiox-Adapter-Thirds-Olympus-Panasonic/dp/B003EAXT5G)
The price is right, though you'll need an EOS camera for iris control. At least you can dust off your lenses...
Thanks mate! I already have kipon mount which is a little better as it has its own aperture blades but you can only stop Down to f4 before seeing vin.
