This vintage Nikon Nikkor-Q Auto 135mm f/3.5 pre-Ai manual focus prime lens is for use with F-mount cameras and adapters. There are a few scuffs and scratches on the barrel's exterior. There is a dent in its filter ring that will prevent the use of a screw-on filter. Its focus and aperture adjustments are both smooth. There is fungus inside but its glass is free of any haze or separation to its elements. There is no oil on its aperture blades.
