Lens is sold as is without an option to return, Please read item description. Lens has screw mount. It was used with JVC BY-10U CCD Camcorder. This is a very nice lens, very high quality, It was used by US Navy. It is heavy, well build, it used to cost $5,000 just 10 years ago. Lens looks mint. And it works. But problem is that it has some kind of soft plastic on the rear . Couple buttons have been smeared with that substance. Not sure why. Other then that lens works. Glass is not scratched, it does not have any haze, or fungus inside. I see couple tiny dust specs inside. But glass looks near mint over all. All the buttons work, focus and zoom works good. Aperture blades open and close properly, it has no known other problems, other then that plastic like substance on couple buttons. It seems that owner has tried to prevent to change the setting on those buttons. Shipping is free within USA and $35 worldwide via USPS first class mail service.
