Rob, J12 can have QC issues, trust me on that. I had to re-collimate my black Kiev-mount one, it was so off that apertures wider than f/8 were unusable.
There are a bunch of Mir series SLR lenses in 20 to 28mm focal lengths not mentioned here. They were made in K, M42, Nikon and Kiev-15 mounts.
Mir-1 is also an SLR lens. An early retrofocal design with compromises to image quality. Mir-1v (Мир-1В) type reputed to be worse than older, KMZ-made chrome Mir-1.
Jupiter-12 is a faithful copy of pre-war Zeiss Biogon. Softish at 2.8, rapidly improves from f/4 and on. I think the earlier (esp. KMZ-made) samples are better than black Lytkarino-made ones.
Russar-MR2 is the only consumer lens of Russar type ever made. Russar type was designed for aerial photography, the advantages are nearly non-existent distortion and 0% geometric vignetting. Yes, 0% - that was the patented part of it. Super-Angulon, for instance, had it at 44%. Ludwig Bertele's postwar 35 and 21 Biogons are derivations of Russar.
Orion-15 is an adaptation of Zeiss Topogon, also an aerial lens design. This design requires extremely precise assembly, hence the aperture on consumer Soviet copy was limited to f/6.
