With 65 grams and a 33 by 39 mm size, the TV-Heligon 19mm, or its optical bloc, is a tiny lens, very different from the other fast lenses often seen here. The 1cm working distance is too short for practical use on F mount but on CX or on a Sony Nex it reaches between 5 or 8 cm, depending on the configuration and the lens being mounted straight or reversed.
In its raw form, it looks like picture 1 below. Hopefully, the optical block is in one piece and, unscrewed, reveals a M30 inner thread perfectly suitable to attach all sorts of eBay adapters.
However, the easiest mount is reversed and stuck on a Nikon CF, which is a perfect fit for its outside diameter. 2 rubber bands for security and it’s done. In this configuration, the working distance is 6 cm and puts a 43mm wide field of view on sensor.

so long as it work :o :o :o

Special, Bruno. Gives some nice results, especially the softness.
-
It works for me, Richard.
Thanks Hans, like the other Heligons, it is mostly fun exploration.

The normal orientation seems to work nicely：fair sharpness in dreamy bokeh and flare.

Bruno, these are magical!

Very dreamy :D

Thank you, guys.
Jakov, we should perhaps rejuvenate this idea of an Heligon meet up :)

I found some old files, all with the V1. By the nature of the lens they could also belong to the unsharp thread but this contraption is much more of a geeky nature.

It vignettes on the NEX-5 but it allows to go close
