Here are a few of links to lists of available lenses for m4/3rds cameras including Olympus, Panasonic and Kodak ( if you can find one) The most comprehensive list includes 4/3 lenses which require an adapter but are fully functional, the only issue being phase/contrast focus issues on most of the bodies.
There are over 120 lenses listed from fish eye and 3D to super telephoto.
