From the Nikon Journal (Vol. 3, No. 4, September 31st, 1986)
This seven element three group SONNAR design was the first attempt by N-K to produce a high speed normal lens. The formula is presumed to be identical to that of the ZEISS 50/1.5 SONNAR. A rigid chrome plated parallel focussing mount provided stops to f11. The optic had a non rangefinder coupled close focus range to 1.5 feet. Accessory size was P42/S40.5 so all hoods and caps available for the 5/2 could be used. Angle of view was 46 degrees. One serial number batch is known: 907XXX. Early units have a larger, less refined block engraving style while later units have the usual style associated with the later 5/2 and 5/1.4 lenses. This lens was very short lived; introduced early in i950, it was discontinued before the year was out because of the appearance of the 5/1.4. All are engraved "Tokyo". It was the premium normal optic offered with the early NICCA and TOWER III cameras. The 5/1.5 was one of the lenses that gained an excellent reputation with combat photographers in Korea. Its early demise to make way for the 5/1.4 was probably due to a desire on the part of N-K to secure the prestige of the world’s fastest normal lens as quickly as possible.
From the editor
Standard lens for the Nicca 3. It was produced for a short time and was quickly replaced by the Nikkor-S 50/1.4 with a different optical design. Optically the 50/1.5 was based on the pre-war Carl Zeiss Jena Sonnar 50/1.5 for CONTAX rangefinder cameras.
