It depends on what you're intending to shoot and whether you need a fast lens or not. A bit more info. about what you will be photographing, along with your budget, would help.
The Panasonic 100-300 or the Olympus 75-300 are capable of some great shots. Take a look in the Panasonic G series owners thread at what @srhmoto has taken.
if you're looking for a telescope for it then i can't help.
