This very handsome rare vintage Piesker & Co. Berlin Piconar 40mm f/4.5 lens is for use with Exakta EXA mount cameras and adapters. There is some light scuffing, minor discoloration, and a few tiny scratches on the barrel's exterior and on its mount. There is also a light 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. There is a small amount of oil on its aperture blades.
