Not much to say other than I used this one for years and it was a fine lens and still is. I switched to a Schneider Componon-S lens and I'm not sure I can really tell any difference. The glass and mechanics are fine, but the lens is not mint but it will produce as fine an image as a new one. Specifically, the barrel has some dings on it. I have no idea where they came from....I received it this way. There also seems to be a speck or two on the glass. I suspect it will clean off it you care to. It has a retaining ring included. $35 plus $6 for priority mail in US. Payment via paypal.
