The Helios 44-2 is a 58mm Russian prime lens Manufactured from 1958 until 1992 (more recently the reinvention 40-2 85mm F/2). The optical design and formula are based on the Zeiss Biotar 58/2, it is thought the design and optical formula were taken from the Russian occupied Germany after WWII. Since the introduction in 1958, the Helios 44-2 and other Helios lenses alike were subject to mass production. I have a couple of these lenses and image quality and colour rendering does differ slightly, due to manufacturing techniques and QC changing from the 50's to 90's (among other things).

The MIR-1b is a Soviet Era lens first produced In 1958 by the KMZ factory, just outside of Moscow, it is considered to be a moderate wide angle prime based on the Carl Zeiss Jena Flektogon 35mm 2.8. 

Another Russian Gem is this little Jupiter 8, utilising the 40.5mm filter thread, this will give an idea of the small stature of this lens. A post war copy of the Zeiss sonnar 50mm F/2, if a compact lens to couple your mirrorless camera is what your after, this could be the lens for you. Similar price range to the Industar 55 2.8 this is another one of the cheaper (already cheap) soviet lenses. 

The Industar 55 F/2.8 was made in the Arsenal factory in Ukraine, like many 60's, 70's and 80's lenses to come from the Ukraine or Russia the lens creates some beautiful images with a very small price tag. I paid roughly $20 AUD delivered to my house from the Ukraine. The aesthetics of the lens attached to my A7r is slimline and compact, exactly what I need for travel photography. Like all of the Russian / Soviet lenses this is also manual focus, a challenge at first, but rewarding once confident.
