I've got a nice Hexanon 57mm f/1.2 with a micro 4/3's adapter. It's in good shape with no mark on the glass or dust that I can see. The aperture and focus rings turn smoothly with no problems. I'll perform a closer inspection with better light later tonight, but I don't remember seeing any marks on the body. It's a nice lens to use on m43 bodies with it's f/1.2 light gathering capability. I sold my GF1 and don't need this lens anymore. Please give it a good home! I'm asking $350 (OBO) Paypal'd and shipped in the lower 48 US. I don't mind shipping overseas, but we'll have to negotiate shipping costs since it does cost more and I actually have to make a physical trip down to the post office. I have excellent feedback at eBay and fredmiranda.com if you're worried about that. Send me a message and I'll point you to my feedback.
