Nikon began their venture into ultra-wide photographic lenses for their Nikon F system with the creation of the 15mm ultra-wide angle lens, followed by the ultra-wide 18mm f/4 AI lens shortly afterwards.
This variation of the Nikkor 18mm Ultra-Wide lens sports a faster aperture of f/3.5 & also uses Nikon's CSC (close focus correction) technology to improve optical performance down to the closest focus setting of 0.25m.
This Nikkor 18mm f/3.5 AI-S Ultra Wide Angle lens is in Very Good cosmetic & mechanical condition. The optical condition of the lens is Very Good with a very small abrasion to the rear element.
