Title: An easy way to adapt the Heligon 42/0.75
Post by: Bruno Schroder on January 22, 2017, 21:28:13
Or at least some of them, I’m not sure they are all built the same.

When my Heligon 42/0.75 arrived, a few years ago, it looked like in the first picture below. On this build, the optic block is in one piece, screwed in on an internal 48mm thread with a photograph friendly 0.75 pitch . Adapting it was easy: unscrew the optic block, screw together a K2 and a 48-52mm step ring, screw it on the internal thread, that’s it. For other mounts, there's plenty of 52MM reversing ring to use instead of the K2.

The 1 V1 is great with these shorter focal length Heligons.

Very informative, Bruno.  I saw both configurations (photo#1 and photo #2) for sale and was wondering if these were different versions or merely altered in some way.

This one is very photograph friendly, indeed. I've edited the text to indicate the 0.75 thread pitch

The 1 V1 is great with these shorter focal length Heligons.

It works very well with the Sony Nex too but the 1 V1 is so easier to use. I've modified the text to add these other mounts.

Those endearing blur circles are the hallmark of the 42mm Rodenstock :D

Thank you, Akira. Immediately after I've taken the picture, I tend to mostly see what I missed. It is when I come back to the picture 1 year later, when I have forgotten what I tried and could not do, that I really see the picture for what it is.

Another one then, with more blue circles, Birna.

Thank you again, Akira. From another serie, without blue circles :)
