I am new to the micro 4/3 world and shopping for what to get. Are there any issues with fitting one brand of lenses on the other brand of bodies? The only thing I have found so far is that each brand uses a different anti-vibration setup with Panasonic's built in to the lens and Olympus' built into the body. Thus Oly lenses would not have any on a Panny body - correct? Any other issues? thanks.
