SMC Pentax A 1:2.8 135mm Lens - 5026763 Very Clean. Condition is Used. Shipped with USPS Priority Mail in the USA only. Used this lens when I was shooting with Pentax and then when I switched over to Olympus I used and adaptor and continued to use the lens until I updated my Olympus lens selections. Now I am not shooting with it and it is time to leave it go. Let me know if you have any questions about the lens, I will be happy to answer.
