오래전 니콘은

35mm S-Mount rangefinder Micro-Nikkor.C 1:3.5 f=5cm model과

Nippon Kogaku Japan Micro-NIKKOR 1:5 f=7cm와

Nippon Kogaku Japan Micro-NIKKOR 1:5.6 f=150mm라는 두 가지 모델 및

F마운트 Micro-NIKKOR 55mm/3.5 를 동시에 출시하였습니다.

 

 

Micro-NIKKOR 55mm/3.5를 제외한 렌즈는 매우 휘귀하고,

The Nikon 150 Micro Nikkor is pretty rare. It is a high resolution lens designed for optimum performance at a 10/1 reduction ratio. Useable range: 1/30x-1/5x Picture angle 43 degrees. Corrected chromatic aberation range: 400nm-650nm ( this is not a typo unless it is in the original Nikon spec sheet).  Vignetting 0% at f/8 Distortion 0.1%.  Image size 115mm (4.6").  Resolution 150LP/mm (1/10X e-line) The resolution may be conservative as I've seen a private lab test on one that performed measurably higher. Nikon describes the Micro line this way:   "Micro Nikor lenses offer high resolution, flatness of field, and freedom from astigmatism-qualities that are prerequisites for producing perfece microcopies or microphotographs".
