My son has collected some of these Konishiroku Hexanon - F mount lenses.
He has lent them to me to try.
Here are some images with the Konishiroku Hexanon - F mount - 100mm f2.8
Seems to be a good lens

A. I'd expect a somewhat smoother bokeh from a 100/2.8
B. How do you mount it?

I think he made it or had it made from an extension tube and something M39-ish
M39 to FX is readily available

Here's an official adapter.

I have an extension tube set, it's not the most secure mount, it uses the aperture tab to keep the lens mounted, AR is 1000x better.

Not that one - I'll see if I can get a picture tomorrow.

Thanks Thomas, it is like mine, although mine say Konica FP.
I was hoping for a more robust mount lock, the camera mount seems much more secure than the EX tube setup.

Is it the same optically as the later Hexanon 100mm?

Yes, it seems to be a friction mount in the tab, but it does work.
The 100mm lens seems to be quite short for such a focal length.
As for is it the same optically as the later AR, I really don't know.
As I said, these are my son's lenses and I had them on loan.
He has the 1.8/52 as well which I liked very much

I cobbled together an adapter for the preset versions using an m42 tube,an m39 to m42 ring a homemade copper tube sleeve, dremel and super glue. It was just a friction thing but that made me nervous so I added a steel ring with a set screw. Pictures to follow.

Yes they are. It's a 5 element/4groups construction.
In F-mount there was an auto-aperture and a preset version.

I have the preset version of 100mm, I have 135mm and 35mm in auto aperture. I just tried my adapter on the 35mm and by sheer luck the adapter kisses the auto aperture lever such that stays open or closed. Better to be lucky than good. I could not have planned such a thing!

Pictures to follow. Both with adapter and of the adapter.

The shortest m42 extension tube is just before infinity so a tiny bit of close focus is lost. Of course it is easily regained using a longer extension tube. If the weather cooperates I plan to test it at closer range, being an aficianado of the macro realm.

The pine needles are one tasty shot. And the lake picture has to my eye the typical Konica color rendering, which I recognize in all my Hexanons from the 70s and personally find pleasing.
