The Unique Nikkor-O CRT 55mm f/1.2 Lens
« on: November 21, 2017, 07:28:05 PM »

Using the very helpful lens-tester on CoinImaging.com:

http://coinimaging.com/macro_lens_tests.html?

I was able to test a number of lenses that I often use for close-up photography. The lenses I am looking at here include:

Nikkor-O CRT 55mm f/1.2 Lens
Nikon APO-El-Nikkor 105mm f/5.6
Nikon Printing-Nikkor APO 150mm f/2.8
Schneider MacroVaron 85mm f/4.5

These are four of the best industrial lenses that I know of. Most of you probably know of all these lenses. But something I did not know, although I sensed it, was the uniqueness of Nikkor-O CRT 55mm f/1.2 Lens, not just because of its curvature as used in monitoring CRTs, but how incredibly sharp and good it is at resolving images. I think it is best to just look at these charts. You should be able to see which colored line goes with which lens. They tell the whole story. The CRT Nikkor-O is the dark-blue line.

I would be interested in your remarks.
