There is more to life than increasing its speed

Ultra-Micro-Nikkor 55mm F2

Ultra Micro Nikkor is a very powerful lens. When you have it someday, you will understand that she has one million horsepower.
In 1965, the Ultra Micro Nikkor 55mm F2 lens was released. It is an old lens now, but it is still new. A good historical lens does not age.

Ultra-Micro-Nikkor 55mm F2h Lens Construction

In 1969, Ultra Micro Nikkor 55mm F2 e-line lens was sold for 140,000 Japanese YEN.
A starting salary of a college (university) graduate office worker in 1969 was about 34,000 YEN.
You would understand that the UMN lenses were very expensive at that time.
Even more, the price of the UMN 55mm h-line is more than twice the price of the UMN 55mm e-line.

Brilliant Lens in the Field

I have been using the Ultra Micro Nikkor lenses for over 20 years. I will use the Ultra Micro Nikkor lenses for more than 100 years. 100 years is just like a blink.
