|Konica Hexanon 50mm f/1.7 directly mounted on a Nikomat FTn without an adapter.|

I briefly wrote about this topic in my review last year for the Konica Hexanon 50mm f/1.7. It was legendary and rated as the top sharpest lens when it came out in 1973, it's so sharp even wide at f/1.7 and I can attest to that. There were several versions that came after it, but I read that the f/1.7 version is the most popular.
Konica A/R mount lenses are actually similar to the Nikon F mount! While shopping around, the first time for me to encounter a Konica lens was when I saw one mounted on a Nikon film SLR. Thus I bought that lens and began exploring that idea from there.
K/AR stands for Konica Auto Reflex.
Konica A/R has the shortest flange distance of all the SLR mounts (40.5mm), which is why it can only be useful on mirrorless and micro 4/3 cameras. (They have shorter flange distance than the K/AR mount.)
CAUTION: Before mounting K/AR lenses on Nikon film/digital SLR, please note that it has some protrusions in the rear that need to be grinded to avoid hitting on any parts inside the camera (eg. the mirror).
The last thing you want to know is that mounting K/AR takes the opposite direction that you would twist your Nikon F mount lens to mount.
I've been doing research about possible adapters for my Nikon DSLR, but there is currently only one place where you can find an adapter for K/AR lenses to Nikon film/digital SLRs. The price might be prohibitive for residents of the Philippines (eg. Item price of P2,500.00 + P1,500.00 Shipping to PH). There are, however, plenty of adapters for mirrorless and micro 4/3 cameras.
If that's the case, I think I'm better off getting myself a brand new Nikkor 50mm f/1.8 D.
