【收藏品】Nikon/尼康 NIKKOR-S 50/1.5 Leica L39口 Nippon Kogaku 送滤镜#jp19653
成色97新, 正常使用痕迹, 如图
50mm f/1.5是所有尼康镜头中最罕见的镜头，对应的unsynced Nikon M这部相机生产于1950年，用了不足一年时间研发。这个是尼康的第一个“超高速镜头“。很快被更快的50mm f/1.4所取代。这支镜头用铬制作，令人惊讶的最小光圈为f/11。有时会被那些没有认真留意镜头的人错误认为与它非常相似的50mm f/1.4对买家而言是喜悦，对卖家而言却是沮丧。尼康和徕卡螺口的总产量约为800。估计有300支是徕卡螺口，仅有约500支可以满足旁轴收藏家对拥有尼康第一款超高速镜头的渴望，使得50mm f/1.5比50mm f/1.1更具收藏价值。
The 50mm f/1.5 is one of the rarest of all Nikon lenses, produced less than a year in 1950 for the unsynced Nikon M. It was Nikon's first "Super-speed Lens." The 50mm f/1.5 was soon replaced by the even faster 50mm f/1.4 so Nikon could have temporary bragging rights of producing the world's fastest 50mm lens. It was produced only in chrome, with a surprising minimum aperture of f/11. The 50mm f/1.5 Nikkor has sometimes been mistaken for the very similar 50mm f/1.4 by those who just don't bother to read the f/stops -- to the delight of buyers and dismay of sellers. Total production in both Nikon and Leica screw mounts was about 800. It is estimated about 300 were Leica screw mount, leaving only about 500 to satisfy Nikon rangefinder collector's quest to have Nikon's 1st super speed lens, making the 50mm f/1.5 rarer than even the 50mm f/1.1.
