Or, you can use a thin M42 to m4/3 adapter.  I combined BORG parts depicted here.

M42 lenses are originally for SLRs, so the commonly available M42 to m4/3 adapters are designed to enable the adapted M42 lenses to focus at infinity.  Thus you need to use or make a thinner adapter.

Then you can combine a thin M42 helicoid (readily available), L39 to M42 thread adapter and the thin adapter mentioned above to focus the CRT further than on a DSLR.

I tried this at my D500 first but ERR messages appeared although the camera didnt stop shooting, still not enough mirror clearance?
later i added another ring as spacer and tried it on the Df with the aperture lug turned in, no error messages on the Df.

Just arrived in France from England...
Fons, that combination I showed previously worked fine with the D700 as well.
BTW, I noticed on the picture of your 55mm CRT that the threaded rear doesn't protrude like mine. Seems few mm shorter ?
I didn't bring it with me to France, so can't measure it for comparison.

The second flower with the V1 is nice ! I like the detail of stamens. ;) it reminds me a borage flower.

Francis, Fons leaves the retaining ring on the thread, which is why the rear thread is not protruding.

Hope you enjoy your stay in France, anyway!

Yep, exactly, same idea I descibed using different tools...

I've used Nikon and Canon DSLRs as well as Sony, Pansonic and Olympus mirrorless camears.  The lenses of all brands came and left.  In retrospect, this CRT has been the only lens that have stayed with me ever since I had gotten it and have been attached all these cameras.

These were shot with D750 today, wide open.

You are welcome, Fons, and thank you for the kind words!  Hope you enjoy the lens.

Thank you, Armando.  The focus is a bit off, but I liked the overall atmosphere.

I have a number of Oscillo lenses, including a crazy 86mm f1.2 STL-Elgeet made for TRW Space Technology Laboratories (that is extremely radioactive, with at least two thorium elements), but I love the CRT Nikkor. I have two, one of the 7x series and one of the 8x series. These lenses are not the same! The 8x has more field curvature (seemingly) resulting in a bit different look of OOF highlights at the edges.
