The newest nano USM revision with a small lcd display on the side of the unit. A surprisingly really nice lens, but havnt ever needed to use it with street photography. No cosmetic damage or paint scuffs, but owner before me was a smoker. When I bought it I removed all rubber pieces and treated them for a few weeks to remove any smell/residue, then used a combination of baking soda in a box inside my house with the lens in the box + dryer sheets (actually like the best technique I've found, surprised people don't talk about this) to remove the smells. Willing to ship/ meet up in person. Will make trades for 50mm stm II 1.8 and a Rokinon cinema 95mm f1.5 / cash, otherwise not really looking for other lenses than those (why I wanna sell this) Retail - 550
