Nikon EL-NIKKOR 50mm 1 : 2.8 Enlarging Lens with mount board is a great product for photographers who like to make prints of their pictures in the darkroom. The lens is compatible with Nikon cameras and the mount board is an added bonus that comes with the purchase. This product is suitable for anyone who enjoys photography and wants to create high-quality prints. Good used condition, lens needs a cleaning, mounting plate has some scratches. Thanks for looking.
