This vintage zebra stripped Carl Zeiss Jena Sonnar 135mm f/3.5 manual focus telephoto lens is for use with M42 screw mount cameras and adapters. The tiny aperture pin on the backside gets stuck and needs to be manually pulled out. There are a few scuffs and scratches on the exterior of the barrel and there are a couple of dust particles and blotchy haze inside of it. Its focus and aperture adjustments are both smooth and its glass is free of any fungus or separation to its elements.
