I am selling the M-system and this is my only lens left. It's on like new condition and works like a charm. I had no focus issues with this lens (or the M8 for that matter). The lens is not 6-bit coded. Comes with box, papers, case and caps. I have a short write-up on the lens and some sample images posted here. $950 plus $20 US shipping. I prefer a Paypal eCheck. If paying with a Paypal balance or credit card, add 3%.
