Please note that even if you purchase this item now, shipping will be after late February 2026. This is a telephoto zoom lens for PENTAX medium format film cameras and PENTAX digital medium format cameras, with a Pentax 645 mount. It's an 80-160 F4.5 constant aperture lens. (The equivalent focal length differs between film medium format and digital medium format.) Operation has been confirmed using a PENTAX 645N Ⅱ, and the AF, MF, aperture operation, etc., have been checked by taking test shots. AF is good both indoors and outdoors. The optics are free of mold and fogging, and dust is only noticeable upon close inspection, making it a beautiful item. The aperture is also clean. Regarding the exterior, there are scratches associated with use, mainly on the lens hood. Please enlarge and check the exterior photos carefully, as they show various angles. I believe there are no significant scratches that would severely damage the appearance. It comes with a rare dedicated case. Thank you for your interest. - Brand: PENTAX - Model: SMC PENTAX-FA 645 ZOOM 1:4.5 80-160mm - PENTAX 645 Mount - Accessories: Lens hood, lens case - Lens Coating: Multi-coating - Autofocus Function: Yes - Focal Length: 80-160mm Other features: Genuine lens hood, genuine front lens cap, genuine rear lens cap, with genuine lens case
