Hello:

I used to have one of these in the 12x form & gave it away (how I got it).

I assume it was from a photolab printer.

I found another set of 12x thru 24x versions.

Anyone know if the magnification implies a focal length (like diopter number being convertible to focal length), or is it referenced to the machine they were used on, something the user did not need to know?

Or maybe someone knows what the optical setup was on Fuji Photo printers that would make the magnifications meaningful?

Thank you

Murray
 
Good idea.

I saw a picture online of one embedded in a lens cone of sorts, with set screws possibly gripping the thin (widest) ring. No threads. Round fixed aperture.

They have a fine helicoid that moves a very small distance.

I don't actually have these in my hands. Just bought them for some inexplicable reason. Will arrive soon.


 
Oh, come on, Murray. They had to have been quite inexpensive. You get great pleasure from finding ways to put cheap white elephants to work.

:O)

Yes...might come i handy for crossing the Alps some day! Yes, can't resist Murray-rigging things.

I am trying to get rid of things, but I backslid. Sometimes I have to resort to slipping extra items in people's packages. John Minnicks did that to me once. He offered two tiny cine lenses to two people, for the cost of shipping. He charged for a medium Priority Flat Rate box & the other recipient complained about paying that much. I did not. There were 7 or 8 lenses in my box, including my first Fuji specimen of this type. I don't know what the other recipient got.

Opinion has it they were probably for Minilab photo printers, but Google delivers so much irrelevant Fuji info I have never found much other than seller listings.

Ok, so maybe different magnifications for different size enlargements as the machines were probably fixed dimensions, unlike a conventional darkroom enlarger with a head that moves up and down.
 
I got some similar machine printing lens for 'no explicable reason,' also. The zoom Betavaron.
 
More than 45 years ago, I used to operate a Durst Miniprinter semi automatic mini-printer.
IIRC, each time I switched film formats, I would have to turn out the lights on the darkroom side, open the light-tight doors at the back of the housing, reach in and grab the removable lens mount with the existing lens on it and switch it with the lens mount with the new lens on it.
Followed of course by closing the doors before turning the darkroom lights back on.
Here is an internet image showing someone from the 1980s using a similar Durst unit:
