Like virtually all camera makers, Nikon's camera mount is propriatory to Nikon, but there are third party manufacturers - Sigma and Tamron are probably the most well known - who make compatible lenses.
The four thirds standard was formed by Eastman Kodak and Olympus. As of 2006, members consisted of Eastman Kodak, Fuji, Leica, Olympus, Panasonic, Sanyo and Sigma.
Yes, it will fit. However, you will still need to see if the lens you have has or does not have features like autofocus or CPU connectors that will carry all the info that your camera needs...
