That's why l like LTM too, there are more choices from different lens makers.
Sankyō Kōki 三協光機 made some nice lens, often branded as Komura, Acall, Force, etc. I have the 35mm f/3.5(double-gause type) in both M39 and Contax/KIEV mount. I've used them on Zorki and KIEV.
I think some of these "off brand" lenses (like Komura) are sleepers. We know that the Pentax 43/1.9 LTM lens is supposed to be excellent. Same with the Olympus 40/2.8. Oh, and the Fujinons...I dream of the 50/1.2, or how about the Konica Hexanon 60/1.2? All these and more are true world class, top-level lenses. And they'll work just fine on a Zorki-C provided the RF is in adjustment 😀
More "down to earth" lenses of very high performance might include the Nikkor 50/1.4, the Avenon 21/2.8, or even the Canon 35/2 which is a pretty decent lens that compares very favorably with early Leica offerings.
And then......there's the "modern" stuff from Cosina/Voigtlander. Even MORE choices! Wow! And the CV lenses are wonderful. (How do I know?)🙄
OP, I really think you should consider an LTM body. Get into this system. You can just grab a Fed-3 and Jupiter-8, start shooting great photos, and work on the next addition to the family at your leisure. Lenses and bodies, accessory viewfinders, maybe a decent meter to along with all this stuff. Sure, some day add a Leica to the clan, maybe some Leica lenses too (e.g., a classic Elmar 50/3.5).
