Nikon f. M39 W-Nikkor.C 2,5/35mm

With original cap, case and box. The Nikon W-NIKKOR·35mm f/2.5 was a popular wide-angle lens for Nikon's 1950s rangefinder cameras. This old lens' performance can exceed modern SLR lenses. This is because rangefinder lenses are designed without the compromise of having to avoid the flipping SLR mirror. Rangefinder lenses can get much closer to the film if the designer wants them to. This 3.5cm lens is one of the good ones that was over-designed for its era, so it still performs wonderfully today. It's a tiny lens: the size of a slightly flattened golf ball weighing under 4 oz. (111g)! Nikon (Nippon Kogaku) calls this the W-NIKKOR·C 3.5cm f/2.5. "W" means wide. 6 elements in 4 groups. Conventional spherical, symmetrical design with two cemented doublets on each side of the diaphragm, and two additional single elements in front and back. This is a design still used today for normal lenses. Single-coated in blue and amber. 8 reversed-curved blades. The lack of straight sections will probably eliminate sunstars at moderate apertures. Mount: M39 rangefinder coupled screw mount, external bayonet. Also Nikon S mount was available of course.
