Photographic enlarging lenses

EL-Nikkor

The EL-Nikkor series of lenses are designed for photographic enlargers. Most feature 39mm Leica thread mounts, although some feature a 50mm screw mount. Most are 6-element, 4-group designs. Some slower, lower-cost designs (marked †) are 4-element, 3-group designs. Newer versions of these lenses are marked with an "N" (focal lengths to 105mm) or "A" (focal lengths from 135mm). (Per Nikon, Inc. Technical and Service Support (800-645-6689), manufacture and sale of all enlarging lenses has been discontinued.)
