Thank you! I have relied on it for purchases.
Thanks, that's been a project of mine for several years and continues to be updated as I get new brochures or specifications from manufacturers/agents/magazines etc. It's a work in progress.
Thanks to all for your help! I just bought a "Schneider-Kreuznach Componon-S 5.6 / 100mm Enlarging Lens" on the auction site. The price was right (I think; haven't seen it yet). And hopefully, I can make it work.
Apparently, there are two versions of this lens, and I think the one I am getting will have the M32.5x0.5 mounting threads (thanks to the Photo Cornucopia for that spec!).
But maybe I should have found an adapter before I bought the lens. I have found a "M32.5x0.5 female to M42x1 male thread adapter" - for $20.
I'm in the process of putting together what I will need to use a micro 4/3 camera on a Bowens Illumitran that I'll be borrowing.
I'm thinking that a 105mm enlarging lens will most likely work best, but we will see.
The Bowens unit is currently set up for Nikon film and digital bodies. Fun times with adapters!
Markjwyatt, i started jurney in DSLR negative copy process 6-7 years ago and was basicaly doing it on my own with out much resources from outside. Basic lines were: Nikon APSC body, bw 35 negatives, later to expand to 6x6. Always at f8 or around. At first I made my own rig based on Nikon F belows holder and then Ps-4 negative holder and Micro Nikkors. Then moving to PB5 and PS-4. Tried many lenses. But had to stop at one moment. Life is too short to try all possible combinations
I am going to wait until I have the lens in hand and have measured it before I order the adaptor. The auction photo looks like something may be already screwed onto the back threads. Maybe it's something I can use.Get it. Once you have that you should be able to furhter adapt to M39 (Leica) if needed.

Funny, I started out asking about one rare thread - and ended up buying another. Anyway, if the lens does have the odd M32.5x0.5 threads, I have located adaptors to go to either M39 or M42x1, so I should be able to find bellows in one of those. The source jjphoto mentioned in post #4 has both adapters. Thanks jjphoto!
My Durst side copier came with an M42-M39 adapter also. This is a pretty common adapter for copy set-ups that use enlarging lenses.
Yeah, that's the issue with most of the micro Nikkor 55mm lenses. The first version (the one I have) actually does a really good job with macro. But it's kind of a one trick pony, and is terrible at infinity. Most photographers don't want a one trick pony, however, so Nikon redesigned the lens so that all of the versions after the first version do better at infinity, with the expense being softer at macro distances. It allowed them to sell more lenses that way, but took away the only real reason to own a micro Nikkor 55mm (in my opinion) over a nifty fifty. Hence why I was saying a good macro lens CAV work really well, but finding a good macro lens isn't easy. Even so, it won't beat an APO enlarging lens. But then again, an APO lens isn't as important with digital, where you can "fix" chromatic aberrations in software, as it is in the analog realm, where you get what you get. Of course, it's always better to get it right in the camera than to try to fix it in post.You will be way better with good 80mm enlarger lens on APSC sensor than macro lens. I tryed Micro Nikkors 3.5 , 2.8/55 and Zeiss Makro Planar ZF2 2/50mm. Any enlarger lens I tried was better than them.
Are you saying your Durst came with adapters for adapting M32.5x0.5 threads to M39 or M42?
...
I use the following setup:
View attachment 217588
From back to front:
Sony A6000
Sony->Nikon adapter
Nikon PB-5 bellow
Nikon->M39 adapter
Rodenstock Apo-Rodagon N 50/2.8
Nikon PS-4 film duplicating holder
Custom bracket
LED panel
Actually, I have now swapped the Rodagon-N for a Rodagon-D2X (better border sharpness).
The camera is oriented in portrait mode because I prefer stitching 3 vertical shots for each 35mm frame (better resolving power, no it's not wasted resolution).
That's a good point. I originally made a skirt for my setup, which isn't as elaborate being a lightboard set below a tripod, but later found out it was easier to just mask off the light around the negative (I use a traditional enlarger negative carrier for this) and turning off the room lights before exposing.Nice set-up. This is similar to what I was working on with the Pentax Bellows II (plus slide copier). Do you shield the gap between the lens and slide? The Pentax slide copier has a secondary bellows to cut out extraneous light, and without it (or some type of shielding), glare destroys contrast. With the Durst unit it is not an issue because the light source in the base is much brighter than room lighting .
What I really wanted to get at was whether any of the lenses you listed had results you could not have been happy with?
Do you shield the gap between the lens and slide?
Yes, the slide holder has its own retractable mini-bellows. I retracted it for the picture (to show the lens).
I own my Nikkor 3.5/55 Ai for the last 30+ years and it was up to any task until I tried it with close to 1:1 copy ratios.
Nice set up Fer.
Actually I'm using the D2X version (optimized for 1.5-2.5x enlargement) because I could not source the "D". Still excellent.
