L-HEXANON 50mm/F1.9 Photo example (LEICA M9)
Impression
It appears that the lens was sold bundled with a Japanese L39 screw mount camera, and information is inconsistent because it is an older lens. I think the information on the referenced link is well organized as far as lens information goes.
Since the lens was made in Japan, it is relatively common to see it in the used lens 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.
Since many old 50mm lenses have problems in lens condition, I feel that it is difficult to use them with full size sensors. 50mm lenses can be purchased at fairly low prices for the latest lenses, so I don’t think there is any reason to actively choose old lenses except for the sake of enjoying them.
