Lens has M42 mount. Lens will be shipped as pictured, without any caps. Lens will be shipped as pictured, so please look at the pictures above. Shipping is free within USA and $10 via USPS first class air mail service worldwide. You can choose faster (and more expensive ) shipping if desired during checkout. Cosmetic Condition: Lens has been used, but it is in excellent cosmetic condition. It looks very nice. I don't see any noticeable scratches on front or rear glass coating. I don't see any haze or fungus inside. But lens has couple very very tiny (0.01mm) dust specs inside the glass elements. Dust does not show up in pictures. I'd say glass looks very nice and near mint condition over all. Glass is very clean and bright. Everything works good. Lens has been fully tested by our tech guys. I guaranty that it will arrive as described or your money back.
