Folks,
Do you know if an enlarger M39 lens thread is the same as Leica LTM? If so, will it be compatible with the M39 to M42 adapter rings? I know that LTM is different to Russian M39? But it is different only with respect to the lens register right?
Thanks,
Si |

the thread should be axactly the same, only the design for Leica or for Russian rangefinders like Zorki and Fed for the register distance is different |

The register distance is very different from enlarger lens to enlarger lens. You need a good bellows or a helicoid for focusing. It's usually easier to reach infinity with longer focal lenghts.

Not all enlarger lenses are M39. M39 is a common thread on enlarger lenses, but you will find a wide range of threads even on later German-made lenses.
Besides this, a lot of older enlarger lenses were made in lensboard-type mounts with jamnuts and flange fittings with unique threads.

If people say M39 in connection with lenses, they usually mean Leica thread mount - M39x26tpi Whitworth. Which is not compatible with M39x0.75 to M42x0.75 filter adapter rings! There also were "enlarger" lenses with all-metric (M39x.5 as well as x.75) thread around, in particular by Schneider and Rodenstock (whose popular Componon and Rodagon "enlarger" lenses really were multi-purpose series that saw more use in copiers, phototypesetters and other process equipment than in enlargers), so beware.

The easy and cheap way to mount any enlarger lens with an ambiguous mount is to get a cheap plastic M42 or [your camera here] body cap and cut a hole in it for the EL. Yes, those threads MAY be standard M39 or M42, or something close, or something in inches, or something totally different. Make a 'custom' adapter from a body cap and it doesn't matter.

Thanks for the tips!
What I have is a Schneider Kreuznach WA-COMPONON 40mm F4:
A 6-element, 3-group line wide-angle enlarging lens
40 mm f/4 (for 35 mm)
(source: http://en.wikipedia.org/wiki/Schneider_Kreuznach)
I got it for <€25 
http://forum.mflenses.com/viewtopic,p,1195818.html#1195818
The same as this one:
Click here to see on Ebay
I would like to use this with Olympus Telescopic Auto Tube 65–116:
http://www.alanwood.net/photography/olympus/telescopic-auto-tube.html
You may ask why? See here, it makes a great macro lens:
http://coinimaging.com/Lens_tests.html
http://coinimaging.com/s50comp.html
So will it be a M39x0.5? 
Thx. |

Leica's earliest normal lenses were usable as enlarging lenses. The earliest Leica enlargers were set up to use the camera lens. That's why the thread is the same. |

I have a Russian set of bellows in M39, I use it with my enlarger lenses via and M39-M42 adapter I made from the M39 mount from a broken Zenit and a 5mm M42 extension tube, works a treat for macro. My favourite lenses to use with it are my 5cm and 9cm Ross Resolux's.

That's very helpful. Thanks. I was looking around and found these:

It is a M43 female to male T2 mount. So with a T2 to OM, I should achieve the result I am looking for provided it is M43 x0.75 to M42 x0.75 threads. |

The drawing shows a M39x26tpi mount. But that is the leaflet for the enlarger lens - many of those around today had some different history. Schneider sold more Componons to copier, scanner and phototypesetter makers than for enlarger use, and these process Componons may look the same as enlarger lenses (some have added cogs or levers), but come in a variety of different threads.

Thanks Sevo. It is a Leica M39 thread mount then.

To me, the lens I bought does match the photo and description as an "enlarger" lens. See here (pdf brochure vs actual item I bought):
Also another reference
