Nikon CRT-Nikkor Auto 1.0/58mm *

The fastest and probably rarest lens in Nikon F mount ever made. The CRT-Nikkor 58mm f1.0 was designed for use with an oscilloscope. "CRT" is the abbreviation for 'Cathode Ray Tube'. Produced in the early to mid 1970's. The lens was designed (red engraved 'M = 1/4') for rays of 404.7 µm (h-line) wavelength. It is extremely rare and almost unknown - only few examples appeared on the market in the last 15 years! The offered lens is in beautiful, mint condition, with optics in outstanding condition, together with its original certificate, plastic keeper, front lens cap and maker's box.
