This is a Nikon Ai-s NIKKOR 35mm 1:2 lens. It also appears to be labeled as AI 35mm F2S. It was sent for maintenance a year ago, including cleaning of the optical system and helicoid grease-up. It has been used since the maintenance, so there may be some dust and debris inside. However, it is in relatively good condition for its age, and it doesn't seem to affect the image quality. I don't think there is any haze, but please judge from the photos. The focus ring has appropriate torque and is smooth. The aperture blades function without any problems. Accessories include front and rear caps, and a hood. Please refrain from purchasing if you are concerned about scratches on the exterior or dust and debris in the optical system, as this is an old lens. It is also for sale on other sites, so please forgive me if it sells out.
