My newest addition to a growing collection of interchangeable lens mounts
is this Komura for Nikon AI. Got it on eBay new-in-box for a few dollars.

Now to find a Komura lens that accepts it!

Nice! It will be not easy , not so common lenses. Let we us how it will be successful.

That would be the last version of the Komura interchangable mount lenses.

These come up on ebay with some regularity, though few, all zooms that I've seen.

Look for "Komuranon" indeed, not Komura.

That's the spirit DOF! I'll wander over to the inventory and take a look at a Komuranon zoom I have and see if the mount comes off.

Back in the early 70s I found something called a Canon Accesory Coupler. It was another 12 or 15 years before I got the Canon 7 to go under it!

Some how my Komura zoom 90-250/4.5 is using this Komuranon
universal mount (?). Mine is SR mount i.e. Minolta MC/MD mount.

Mine is model 820 in OM mount. 80~200/4.5. If the mount DOF shows works on this lens I haven't discovered how to remove and replace yet. While I was removing screws and parts I did fix a focus-zoom problem. Even got it back together again!

Hi Koji,

There were several Komura universal mounts.

I have the 90-250 and it has the "Uni-Auto" mount from about 1970.

This one is different.

The widest aperture marking on this mount is f/4.5 so I assume that does
mean they only made zooms or perhaps a 200-300mm telephoto for this
system.
