Just stumbled upon this snippet of hitherto unknown to me information, that means I should be able once again to use the bag full of pristine Canon FD lenses that have been gathering dust for the last twenty-odd years. (Including my beloved 85mm f1.2L

).
Novoflex have a range of adapters that will fit many manufacturers old manual focus lenses onto any of today's currently available Micro Four Thirds cameras. (including Olympus OM, Pentax K, M42, Minolta MD, Nikon F, Contax/Yashica, Leica M & R, Sony/Mnolta/Alpha).
Novoflex brings mount adapters for Micro Four Thirds: Digital Photography Review
Obviously only for manual focussing, but full focus to infinity is available, along with stop down metering and aperture priority auto.
I'm not sure of the position with other makes, but full focus to infinity has been the stumbling block for all these years with any attempt to use Canon FD lenses on modern day digital DSLR's.
Unlike some no-name obscure suppliers of adapters, Novoflex is a very well respected company, and these adaptors look to be very good quality. I may well be tempted to obtain a micro four thirds body, just to have the pleasure of using my old FD lenses again.
They also have a Canon to Nikon adapter that allows any modern day Nikon lens to be used directly on any Canon DSLR !
