Konishiroku Hexanon 52mm f1.4

jjjfff · 04-24-2023, 08:05 PM

Hello,
I got this lens recently, because it feels heavy and nice, f1.4 is always interesting and 52mm is different. It's dirty but salvageable and I don't know much about it.
It seems it's a Konica mount, it seems there is a rare version of this lens, and it seems it's not easy to adapt to PK (KONISHIROKU HEXANON 52mm 1.4 - LIBRARY OF LENSES)...
Does anyone here know more about it?
Thanks

-J

any adapter that will allow infinity focus will have an additional focusing lens in the adapter, normally producing a poor focus/light path....

it's actually easier to buy a mirrorless body and a proper adapter for that lens....

A bit like Asahi Optical and Pentax or Matsushita and Panasonic, Konishiroku is the name of the company that launched the Konica brand name in 1948 before adopting it for its own in 1987.

The Konishiroku Hexanon lenses are meant for the Konica F/FS/FP/FM SLRs from the early 1960s. The corresponding mount is named the Konica F mount, not to be confused with the subsequent and much more common Konica AR mount (AR = Auto-Reflex).
