I've got a Nikon 55mm f/2.8 Micro AIS lens that I am trying to sell. Since I purchased my Panasonic 45mm macro, I have not used this lens at all. The lens is in pretty good condition and its working properly! No scratches in the front or rear element, no fungus, no oil in aperture blades and the focus is pretty smooth. For $150 Shipped and Paypal'd, you will get the lens and a free Fotodiox Nikon F-mount to M-4/3 adapter.
