Sorry if this is a real numbty-type question, but I couln't find the answer anywhere via Google (probably asking the wrong questions!). I have a Panasonic G1 and the excellent Panasonic 20mm F1.7 lens. I may also be getting an Olympus Four Thirds camera and abviously would like to use the "pancake" on that. So the question is "can you"? I know it is possible to use Four Thirds lenses on Micro Four Thirds cameras via the MA1 (?) adapter, but is there a Micro Four Thirds to Four Thirds adapter?
