I just got a nice Olympus E-500 camera for $10 at a thrift store and it had a 40-150mm Olympus MFT lens on it. The mount seems extremely close (same mounting dot location and data connection location) to my current PEN E-PL7, but it does not fit because the mount is slightly different. My question is, is there an adapter to use lenses from the E-500 on my PEN E-PL7? Also, what is the name of the older E-500 mount? Thanks!
