Ultra Micro Nikkor 165mm the Emperor of the Lens

Ultra Micro Nikkor 165mm F4

The Ultra Micro Nikkor 165mm F4 is the most graceful lens in the Ultra-Micro-Nikkor series.
This lens is called "The Emperor of the Lens".
It was introduced in 1970 from Nippon Kogaku.
The Ultra Micro Nikkor 165mm F4 consisted of seven elements set in a black painted barrel with 82mm screw thread.

Mainly for the production of intermediate negatives required for IC photomask manufacture by the step-and-repeat method, it can also be used to produce photomasks directly from the originals.
In addition to its large image area coverage, it performs roughly the same functions as the Ultra Micro Nikkor 135mm F4 and 155mm F4 lenses.
As its working distance is almost the same as the 135mm F4 lens, it can be used on the same special camera equipment.

To put this lens, I obtained an old cloth. The pattern of old Japan is woven to this cloth.
This cloth is a cultural asset preserved in the Shosoin.
No one can buy the real thing in an old age.
Because, the cloth was made in Japan of 1300 years ago. Then, I bought the cloth of the replica made for the tea ceremony in Japan. I put the graceful lens on the cloth of Shosoin.
The Far Eastern light was seen.
