Exaktar 135mm F2.8 M42 mount bayonet lens lente objektiv + both rigid caps

Description: This sharp lens is in excellent condition, no scratches or fungus or haze. Diaphragm perfect, no oil traces. Optically and mechanically sound. Front and rear rigid thread-in caps included. 

Issues: may show some normal usage marks in body (glass is perfect). May have some inner dust as 99% vintage used lenses have, but very sparse and unimportant. Some little cleaning marks in external lens surfaces, but unimportant.
