Just kidding.
I am the master of typos
This was not embarrassing, I have done much worse other times...
Of course I meant 44-3.
I think the Helios 3 is one of those rare soviet lenses that are game for hard core collectors. Not totally sure though. If I'm wrong, I will stand corrected very soon

Originally posted by stevebrot Thanks! I remember when no-X started his project but have not been back there for awhile. I did not know that he had the resolution numbers for the 44-3, but now I do.
The resolution figures for most (all?) soviet lenses should be available from the GOI site or sovietcams.com.
There are optical designs cut-outs and the original sheets of the various optics, even the uncommon ones.
The values of resolution for center/borders are much lower than what you'd expect, because they were neither theoretical nor measured on the aerial image. They used cheap soviet film instead.
On a good modern sensor the number of lines/mm that the lens can discriminate would be higher.
EDIT:
couldn't find the GOI site, I don't even know if it's still online.
