The Olympus and Panasonic 4/3 lenses work fine on each other's bodies - I've got three Panasonic bodies and use the 75mm Olympus and 60mm macro on them. I'm not aware of any compatability problems with newer bodies/lenses.
Which is why I couldn't find the Olympus 45-200... it's a Panasonic! If it's not too late, OP, I'd take that one back and buy the Olympus 75-300, or the Panasonic 100-300. The Olympus has a much closer minimum focus distance - good for butterflies and other insects, if that means anything, but the Panasonic is 'faster' (has a bigger maximum aperture, both wide and telephoto), meaning it can be set to let in more light, which is useful in poor light.
