L-HEXANON 50mm/F1.9 Photo example (LEICA M9)
Impression
This lens appears to be a lens that was sold bundled with a Japanese screw mount camera, and information is inconsistent because it is an older lens.
I think the information in the reference link is well organized.
Since this lens was made in Japan, it is relatively common to see it in the used market, and there is a wealth of information on the web for an old lens.
There seem to be several variations of the lens barrel, and the one I owned seemed to be an early model, but when I used it with my Leica M9, I sold it because it was too harsh to use with a digital camera, such as halos when backlit.
