This lens is in excellent condition. The focus is smooth; the aperture ring turns freely and precisely. I see no oil on the glass or the aperture blades. The lens hood slides smoothly. There are a few signs of wear, but it is in otherwise great shape. This is a non-AI lens that can be converted to an AI lens for about $35 plus shipping according to several websites. Front and rear lens caps and UV filter are included, as is its original case, which is very worn.
