Oh whoops, blush...i guess someone has to be the biggest idiot!

I must have been searching away
And forgot what time zone I was in
Lucky I'm not an absent minded time traveller
Then again....

Kind of approach, found on german LF forum.

Here is information on how to focus the Fujinon soft-focus lenses -- in the Fujinon lens owner's manual. I can think of no reason it would be different for other SF lenses:

In my experience owning quit a few different SF/ Diffused focus lenses & in my experience they do not ALL work act or alike & no one manufacturers instructions will cover use of all types/makes. The best way to know the SF/diffused optic is through use and "getting to know" the lens.

No offense meant xkeas just my experience.

I have Olde Imagon literature (a lot of it, some in German) which states the Imagon is "focus extending". The idea of a "belt of focus" rather than a "plane of focus" as described in the above attachment, seems about right to me. It is an acquired skill to get used to focus the Imagons. I do love mine and I have am happy to have a complete set from 120mm to 420mm. Somebody should 3D print Imagon discs for $$$, the chances of finding correct original discs (especially the large ones) is miniscule. I know I would buy some

the WOllensak Veritar instruction manual it says to stop the lens down a little and then open it up afterwards to the desired level of softness. works well with imagon, vitax, verito, vesta, fast tessars and homemade Wollaston .. might work with others too .. can't be sure ..

Some times what you see is not what you get

Focusing technique will vary slightly between lenses. What aperture to use can not be adequately judged on the groundglass. You really have to try some different apertures on different subjects to fine tune what you like for sharp versus soft, as the aperture choice affects softness as well as focus. After 50-100 sheets of film, you'll find an aperture choice you like best for that lens and learn to keep the lens at that aperture.
