Rodenstock, to get one...

[golunvolo]

As the title says. The options are so many. Any direction pointing will be ok. I´m looking to get my first very own Rodenstock -thanks Andrea B and all the others that had my imagination fired up.-

   Suggestions?

I'd consider the 100/1.6 which fits nicely in an empty 18-70 shell.

Yes, that's what I did. Bought a discarded 18-70 from the repair shop, removed all its innards, and mounted the Heligon with plenty of epoxy.

Be extremely aware of the potential for confusing the 100/1.5 and 100/1.6. They may look very similar, but optically their properties are miles apart. Not that one is good and the other is bad; rather, the f/1.5 has way too short back flange distance to be useful, even on a mirrorless camera. Thus be absolutely certain the lens has f/1.6 printed or engraved on the casing.

Bjørn J: with that solution, it is a real breeze to add a CPU to your lens. Then you have metering and full EXIF data. The lens has to be "G" with a single fixed aperture of course. But you will get "100 mm f/1.6" as the EXIF descriptor, and the lens will function and be compatible with all modern Nikons. If you didn't throw away the parts from the host lens, all you need is the CPU. Shall I make you one?

[Bjørn J]

Thanks for the info Bjørn. I never throw away lens parts, everything from the lens, even the tiniest screw, is in a plastic bag somewhere

[Bjørn Rørslett]

OK, as a courtesy compliment I'll make you one and it's on the house (this time).

Just have to wait until beginning next week, when I return to Oslo. Meanwhile, look for the bag with the front and rear shields for the contact block,  silver pins (only 5 required), and two small screws with conical heads.

Way back when I made mine I opted for as long a focal distance as I could which meant shaving off the inside of the bayonet and the outside of the lens housing. This means that adding a cpu will be difficult...I believe.

Oh I forgot to say that we now have our DX Heligons Bjørn 😂

I have a 42mm f/.75, 100mm f/1.5, & 100mm f/1.6. The 42mm & 100mm f/1.5 have very short working distances (couple/few inches), as Bjørn R mentioned, the 100mm f/1.6 is much more user friendly (couple feet working distance).

The 100mm f/1.6 I have is the same as the ebay auction linked below, with the same part number (4401-333-824). Though it doesn't say f/1.6 on the lens or in the description, it looks like the same lens mounted in Bjørn J's picture, and is the same model I've seen other members at this site using as well.

The 100mm f/1.5 lens comes in many different housings and seems to always be labelled as an f/1.5 as well.

The price for that one is USD 346.-. Way too much in my opinion. I think I paid USD 65.- for a brand new lens in original box.

I wasn't suggesting to buy that one, just showing which version to look out for.

Thanks Bjørn, I'll see what I can find.

[stenrasmussen]

Here's the rear end of mine. It has a working distance of ca. 130 cm which was my aim as I then have a nice portrait lens.
I tried to get it as far back in the bayonet as I could. Pushing it further would have involved grinding through the lens barrel.

[Bjørn Rørslett]

Give it to Erik. He has this new powerful super-Dremel thingie that makes sparks fly.

I kno...and I am jealoux. All I have is an old fashioned one...with a cord.
A cpu would be nice though.
