500mm F8 reflex lens. Used with a Sony E-mount. I bought it used and used it a few times, but it's been stored in a dry cabinet. I'm not an expert, but I think there might be some dust and debris. It didn't cause any particular problems when I used it. *Notes on purchase* * There is paint peeling as shown in the photos. * There is no rear cap. I also have an EF mount adapter, so if you want it, I'll include it, so please let me know when you purchase. - Model: Tokina 500mm F8 Reflex MF - Country of Manufacture: Japan - Focal Length: 500mm - Aperture: F8 - Macro Function: Yes - Minimum Focusing Distance: 2.7m Thank you for looking.
