I have a 100mm SMC F 1:2.8 Macro for sale. I bought it from a member of the list in 2001. In fact, I found the original message from Stan Halpin offering it: http://www.mail-archive.com/pentax-discuss@pdml.net/msg20022.html
The lens is still in very good condition, it is the best lens I ever had by far (I haven't had many lenses, though!). In the message by Stan you can see it came from a lab and that "there are three visible indentations in the outside of the filter ring. Does NOT hurt the ability to screw on a hood or filter". I have no experience as to be able to judge its condition, but Stan said "aperture, lens surfaces, external cosmetics all in EXC or EXC+" and it keeps working great. I'm selling it to rise the money for a DSLR, I've already sold my 35mm, and . I'm asking the same I payed for it: $300 (+ shipping). I hope someone will enjoy this lens as much as I did. Best wishes, Hernan Mouro Davis, CA.
