This near-mint condition Carl Zeiss Jena Tessar T 50mm f/3.5 manual focus lens has a Burke & James LTM M39 screw mount adapter installed on it and it comes with its original front cap. The only thing holding it back from being mint are a couple of light scuffs on its exterior. Its focus and aperture adjustments are both smooth and its glass is free of any fungus, haze, or separation to its elements.
