SN 465133. Lens is in bellow average condition. It has some fungus webbing inside. And it has light haze inside as well. Luckily it still makes very ice pictures. Fungus seems not affect image quality. Haze is very light. And lens front glass has lots of very fine scratches. So lens has some issues, but it still works good and produces very nice and sharp pictures. Lens shows normal wear on exterior. Filter rim looks good and it accepts filters. Performance: Lens works well. Focus works good. Aperture works well as well. You could use it as is, or get it cleaned. Shipping is free within USA and $15 via USPS first class air mail service worldwide. You can choose faster (and more expensive ) shipping if desired during checkout. It will be mailed as pictured with both caps. Please no returns on this lens. I have described it to the best of my knowledge. It is sold as is, since it has some issues.
