The NIKKOR-Q.C 135mm f/3.5 lens offers excellent descriptive power and beautiful bokeh. - Model Name: NIKKOR-Q.C 135mm f/3.5 - Focal Length: 135mm - Maximum Aperture: f/3.5 - Brand: Nikon Thank you for viewing. The exterior shows some signs of use, but is relatively clean. The focus ring is smooth. The aperture ring has a good click feel. There is no oil on the aperture blades. The lens has been cleaned, but there may be slight dust. There is a line on the front element, which is difficult to see unless you look closely, and is likely related to the coating. Included accessories: Lens caps (front and rear) If you have any questions, I will answer them to the best of my ability. Thank you.
