I love wide-angle perspective, but I don't find myself using my Oly 12 as often as I thought. It's a gem of a lens, but I've got a lot of funds tied up in a lens I don't use much. I hope I don't regret this! It's still in mint condition as far as I can tell, just like the photo except the lens cap plastic protector has finally fallen off. I'm asking $600 to sell outright, free ground shipping to continental US. Just as good, though, would be a trade for the Panasonic 7-14mm. We can negotiate the cash difference if you want to trade.
