And the aperture is also interesting.
It's octagon shape(normal is hexagon or circle)
and it's double layer blades design.

From the missing DOF scale, large aperture value spacing and long MFD, I think it may be designed to use on some surveillance camera. _________________ https://lensfever.com/

I don't think this name plate has been switched. The name plate itself is unlike that of any other Hexanon lens known to me. I have never seen a Hexanon "SL" lens, or one of this vintage with such a short SN. But I am convinced it is a genuine Hexanon item. It has the typical Hexanon finish, proportions, general style, lettering, and color. Most importantly, it has a bona fide looking Konica production code on the mount side: 9T (June 1979).
What the lens' purpose was I have no idea. Calvin83's suggestion sounds very possible. Perhaps the letter "S" in "S"L stands for surveillance? What puzzles me is why such a wide range of apertures for a surveillance lens. On such a lens one would wish for everything to be in focus, right? _________________

Not intended as an SLR lens it seems, as it has no auto mechanism ( no pin).
Also that aperture only goes to f/11 marked.
Would be useful to know if it actually has M42 back focus.
The 42mm thread could just be coincidental. A handy thread to use for whatever equipment it was made for. _________________ I like Pentax DSLR's, Exaktas, M42 bodies of all kinds, strange and cheap Japanese lenses, and am dabbling in medium format/Speed Graphic work. |

SL = Surveillance Lens imho.
Schneider made a version of the C-Curtagon 2.8/35 in a similarly stripped down, industrial barrel with M42 mount, nd thatlens was used in surveillance systems. _________________ I don't care who designed it, who made it or what country it comes from - I just enjoy using it! |

I recently found this lens and it indeed has M42 back focus distance. I'm using it with a thin heliciod on my A7II and I get infinity to quasi-macro. This little lens renders beautifully!

From a quick google I found a reference to 'SL' in context of stereolithography on a konicaminolta site - https://www.konicaminolta.com.au/glossary
I don't know anything about industrial processes - but it could be a clue. _________________ Currently shooting with Fuji X-E2s + Metabones Speedbooster + m42 and CY glass 💕

Beautiful shot kuato.
Do you have a Konica AR 35/2.8 to compare to?
I'm curious what differences between them are, specifically optics and IQ.
Looks similar to the older version...
