Hi, my name is Guido. IÂ´m from germany and I have two intersting lenses sitting here.
Does anyone can tell me something about them? The lenses are sitting in a plane brass tube without any threads. I wonder in which cameras they where used.

And if anybody can tell me how I insert a wroking photo I would be glad. No matter which size I take it wounÂ´t work.
Best regards,
Guido
Sorry, but

You may need to re-upload it as I can't see any photo.

Here a second try. I hope this is now shown correctly.

These two lenses in your photos are made in the 1970s, . They may be made for some industrial device or aviation applications. I am not an export of these lens but someone here might know.

Speed and focal length would make them enlarger lenses, but those usually have a built in aperture, so no.
Projection lenses...too slow for that.

Hmm.....

Well, THIELE has an answer: those were made in a set of 2925 lenses in 1931 for Franke&Heidecke (that means for Rollei). No camera model or use use was mentioned.

Maybe the upper lens in a twin lens camera, before the usual Heidosmat...

They look remarkably well preserved if made in 1931.

Hi folks,
that sounds interesting. I went through the internet searching for twin lens cameras out of that time. Though I havenÂ´t found any Rollei twin lens camera with an Steinhell lens, the focal length and speed of simular cameras are nearly identical. Thank you very much for your support.
Best regards Guido

Seems like they were part of a batch of 1600 pcs. from 1976 but there's no details on what or whom they were made for. Some of the other Cassar 75 mm lenses have "enlarging lenses" in the description, so I think something similar might be the most likely thing the Cassar-S lenses were used for as well. Perhaps for some sort of industrial application, like calvin83 has suggested - copying, printing, inspection?

I'm not sure all Cassar lenses have the same optical design, but most of them seem to be quite simple, mostly triplets. I love my V-Cassarit though (also an enlarging lens from a similar era) so if you can adapt them you might be surprised in a postive way. Steinheil was quite a capable manufacturer after all!

In the box I have here was some more interesting stuff: A Meyer GÃ¶rlitz Plasmat Satz Ser. 4 from 1940. ItÂ´s still working accurate. Only the aperture mechanism is a little stiff.

My question is if there are still people using or collecting this kind of stuff.
Best regards Guido
