In spite of both have M39 thread the lenses from the rangefinder will not fit this SLR. Moreover it's quite hard to find optics for this Zenit.
Well it's not THAT hard unless you want something fancy. You need to spend some time looking. The standard lenses (50/3.5 Industar and 58/2 Helios-44) are easy to find for like $25 with cameras still attached to them. Regarding the Mir-1 37mm wideangle, I see seven currently on eBay and I've seen plenty on flea markets.
The most interesting lens for the old Zenits is probably the 85/1.5 Helios-40 portrait lens:
In the "old" version, which is M39 with a M42 step-up ring, it will fit the Zenit-3M nicely, if a bit on the top-heavy side. I think I paid $60 for mine, with leather case, filters and all.
I can say that I've hardly seen one third of the list. I've NEVER seen Jupiters 9 and 6 for Z3M for example.
As for Helios-40 I have one and I use it on Canon body that is much more comfortable.
Anyway as far as I understand the topic was dealing with usage M39 for RF on a Zenit 3m and probably vice versa ...
Where did you see that? People ask this question every now and then (and are almost always disappointed about the answer), but this time I think the OP just wanted to present the Zenit-3M as the "SLR cousin" of the Zorki 6. He didn't really talk about interchanging lenses as far as I understand it.
I saw it from the formula given.
You mean the "minus rangefinder assembly plus mirror box" thing?

I've said all I wanted to say.
