Used Carl Zeiss Jena Flektogon MC 35mm f/2.4 lens with issues. Casings of this lens looks good, with normal signs of use, as on real pictures. Lens has micro dent on filter ring, but filters screw fine. Glass issues: some points of micro fungus inside and some marks/spots on front glass coatings. Lens has no haze, deep scratches or separations. As most old lenses, lens can have some micro dust inside, few micro marks/spots on coatings and few micro cleaning marks here and there. Focus ring works good, but it is hard at the end and unregular. Aperture blades glued with grease, do not work now. Lens need some care and attention to be again good lens, which i mean good cleaning in lens service.  Lens has M42/EF adapter on it and two caps. My price is 179.99 USD or 'best offer' price. This is 'as is' auction, so no returns or exchanges, all sales are final. I'm also not an expert in lenses, so i've described this lens the best, i could. Thank you !
