This Nikon El-Nikkor 135mm f/5.6 darkroom photo enlarger enlarging lens comes in its original plastic bubble case. Its rear thread is 39mm and it does not come with a mounting ring. There is a slight dent in its nose that will prevent the use of a screw-on filter. Its aperture adjustment is smooth and its glass is free of any fungus, haze, or separation to its elements.
