See, I feel like it'd be difficult to make a big aperture lens in LTM. I don't know why, something to do with the flange distance, maybe? Or just the narrowness of the lens throat. The widest aperture I know of on a LTM lens was a 50mm 1.5 Canon, and those go for more than the camera bodies in good shape now.
Of course, you know, the other thread-mount I care about is even smaller in diameter, but it has an SLR-like flange distance, due to the massive shutter and light box--the Argus C mount. I wonder if there's an m42 or K-mount adapter for Argus like there are for Zenit lenses... You certainly wouldn't adapt it to LTM! It wouldn't link with the rangefinder and the flange distance would mean you would have to mount it on an extension tube. I know there are adapters for it for mirrorless digital, but that's everything.
Canon 50 1.2 LTM.
And Leningrad, it was over complicated for soviet factory technicality. Do not expect it works fine.
