I bought a Panasonic GF-3 kit with the Panasonic 14 f2.5 because I needed a small camera to carry on vacation. I already own a copy of the 14 f2.5 lens so I don't need two . . . even if it is one of my favorite lenses!
This lens is new . . . mounted one time on the GF-3 just to make sure it worked (it does! :-) . . . front and back caps included . . . no box though as it came from the kit.$165 shipped and paypaled. Have over 30 positive feedbacks on fredmiranda . . .
And those are pictures of the pancake 14-42, not the 14/2.5. I have one which has grey at the base. I think the vast majority are like mine, but I've seen pictures on eBay of ones with black base. The lens is so small, I doubt anyone would notice much of a difference.
