Used HASSELBLAD 150mm CARL ZEISS f/4 Sonar Telephoto Lens for 500 series cameras. I bought this lens new and used it for many years. It is in perfect working order. This lens is as sharp as a tack; the lens glass has no scratching or polishing marks. It is used and there are small scratches and small scuffs on the black metal barrel. It comes with front and back lens caps.
