Nikon El NIKKOR 135mm f/5.6 Enlarging Lens - Refurbished by Nikon U.S.A.

Capturing your image on film is only part of the challenge. If your darkroom equipment doesn't perform, your efforts could be wasted. Only El-Nikkor enlarging lenses offer nikon's unmatched optical technology. Constructed of Nikon's own optical glass, El-Nikkor lenses are corrected for chromatic aberration beyond the visible spectrum into near ultraviolet wavelengths to which photographic papers are particularly sensitive. Through the use of special optical glass and matching optic coatings, El-Nikkor lenses are designed for ultraviolet transmission in the 350 to 450mm range. This means El-Nikkor enlarging lenses can be used for color separation in addition to all other enlarging applications. El-Nikkor lenses are also front-threaded to accept screw-in accessories, and can be used for exceptional small-object photography when mounted on a bellows.
