That's what I would like to know, if the red "P" Industar 26 M39 is better than the regular one. I know the red P means it's coated, but nothing else.
What do you think?.

Nope.
By 1960s the П mark (просветленный - coated) was dropped from all products, as lens coating long since ceased to be news to a customer.
Hi,
Well, perhaps...
The problem is that these cameras and lenses are 60 or more years old. Many of them have been sitting in cupboards or drawers (or barns and sheds) since the 80's or 90's when "better" cameras came along. So the condition isn't guaranteed.
My experience is that any lens can be damaged slightly or a lot over the years. So best to be prepared and get them checked. Checked and adjusted you'll probably not see any difference and may well be pleasantly surprised. Of course, if the lens is badly damaged, scratched etc, then age has nothing to do with it.
So, I'll wish you luck and hope you are pleasantly surprised. (It's worse with Leicas, btw. The Summars were a good example of how poor handling etc could ruin a perfectly good lens. And as for those who thought they could regrind them and coat them...)
Regards, David
Assuming they're both properly collimated and undamaged etc, you'll likely find the I-61 is sharper and has more contrast than the I-26. The difference isn't huge but it can be seen in side-by-side comparison shots. The I-61 has low-dispersion lanthanum glass, which (I believe, though no-one seems to have a definitive answer) the I-26 hasn't.Both FSU lenses I have are in excellent condition, or at least that's what it looks like. To test them I will shoot half roll with one and the other half with the other with my Fed 2.
I've taken 18 pictures with a I-61 and now I'm doing the other half with the I-26 red П. Perhaps I'll post the comparison.
Thank you for your kind words.

As for earlier versus later, it's generally true that older FSU gear was better made but they did improve optics over time. Late I-61s, for instance, had poorer build quality, fewer iris blades and printed markings (rather than engraved). Probably the best made I-61s are the so-called "Panda" or "Zebra" ones, black and silver.
