Advertisement Posted February 6, 2015 Posted February 6, 2015 Hi AlessioG, Take a look here Schneider-kreuznach Xenon 1:1,5/50. Any info? . I'm sure you'll find what you were looking for!
sandro Posted February 8, 2015 Share #22 Posted February 8, 2015 Did you ask Schneider-Kreuznach for information? They are always very helpful, checking numbers etc. Very interesting lens, I wish I had one! Lex 1 Link to post Share on other sites More sharing options...

sandro Posted February 12, 2015 Share #26 Posted February 12, 2015 Alessio, when they told you no information was available but the production year, they probably don't have it. At Schneider they are very helpful, like they scanned a folder of some lenses for me. But these companies don't have a proper archive or historical department, so lots of info tend to disappear, unfortunately. Lex Link to post Share on other sites More sharing options...

I understand that thay have not an archive.. But it's a pity that a long story productor haven't an archive of information. That's means history will disappear in future!

Lexx Posted December 17, 2020 Share #28 Posted December 17, 2020 Hello everybody! Found such a lens. What do you think it is and why? Could this be an early version of the lens later made for Leica cameras? Welcome, dear visitor!

derleicaman Posted December 18, 2020 Share #29 Posted December 18, 2020 Looks more like a lens made for a plate camera, or large format camera. The mount is too short to be used on a ltm camera. Most likely screwed into a mount board for a large format camera. 1 Link to post Share on other sites More sharing options...
romanus53 Posted December 18, 2020 Share #30 Posted December 18, 2020 At least it's a wartime Lens so to Lage for some early or prototype 1 Link to post Share on other sites More sharing options...

The mount is too short to be used on a ltm camera. Most likely screwed into a mount board for a large format camera. I thought so too, judging by the appearance and mount. However, the lens has an extremely small flange distance - about 25mm and a coverage circle with a diameter of 45mm, which is fully suitable for a 35mm rangefinder camera. Therefore, I cannot understand its purpose and why I could not find other similar ones. Link to post Share on other sites More sharing options...

romanus53 Posted December 18, 2020 Share #33 Posted December 18, 2020 I was build around 1941, hard to tell what it was used for dependig on the mount. It has no helicoid for focusing, mabe the back of the barrel was lost. Could be for some special purpose either, Roentgen-screen-documentation or special film camera. You could check the diameter of the image-circle and how much space you have to film plane. Link to post Share on other sites More sharing options...
rfaspen Posted December 18, 2020 Share #34 Posted December 18, 2020 I had one of the lenses in the original post. My research at the time just indicated that Schneider made some xenon's in LTM. But, not very many. The lens performed much as expected, but had a bit of haze. Sold it before cleaning...to an excited collector. The lens in the recent posts looks like an LF lens for sure.

romanus53 Posted December 18, 2020 Share #35 Posted December 18, 2020 The first lens shown has a helicoid for focusing, the second not but looks just like a lens-head like the Hektor 13,5 has; with 50 mm focal length you can perhaps cover a single film-plate but I would not call that LF. Back than you would use a 1.5-lens only if you need the speed. Link to post Share on other sites More sharing options...

You could check the diameter of the image-circle and how much space you have to film plane. I'm sure the lens was without a back. It was kept in storage all the time. And in the original box. With the lens there was a ring on the external thread with four holes. But it is not with me now. The back focal distance from the edge is about 23mm, from the large thread about 30mm. The coverage circle is about 5cm in diameter, so it covers the diagonal of a full frame (45mm) without vignetting. Link to post Share on other sites More sharing options...

Lexx Posted March 12, 2021 Share #39 Posted March 12, 2021 Hello everyone! Here are some photos from an early xenon lens I wrote about. And a photo of a lens with a manufactured helicoid.

sandro Posted March 12, 2021 Share #40 Posted March 12, 2021 Nice job that you made a working lens out of it. Interesting results! Still fascinating what the original purpose was for. It was in a batch with only 4 other lenses and in the months immediately before and after no such lens of 5,5 cm was produced. So a special purpose seems obvious, but which purpose?
