My Industar 26 seems to be a poor sample.
Industar 22 collapsible is quite sharp but low contrast.
Industar 61LD has 4 elements and the highest contrast.
Jupiter 8 has 6 elements and the highest resolution of my 4.
Now you will want a small fortune to buy the 28mm Orion. :rolleyes:
I am very pleased with the Industar N-61, the lens which I had previously ordered. It appears to give both good sharpness and contrast as desired. I was very surprised. Based on the info everyone has kindly provided, I believe I will acquire a 61LD, the 22, and then a Jupiter 8, in that order. But, my camera curtain needs a work-over. All the negatives look as though I have been shooting the constellation Sagittarius.
I will share some examples from the N-61 soon.

The Industar 22 collapsible contrast could be improved with a lens hood but they are hard to find or expensive,unless one is home made.
