I just sold my TAIR-11A to create some fund. I got this lens from the usual antique shop. It is so unique that it caught my eyes. After removing 2 M39 extension tubes and mounted on my E-3, I realise it could achieve infinity. I am so delighted that I bought it immediately and brought home to clean it up. It comes with the yellow filter and the 2 M39 extension tubes. Now the questions, what kind of camera is this lens for ? Is this lens in some sort of self created mount and helicoid ? It look so crude and simple.
The lens says :
Zeiss Ikon A-G Dresden
Carl Zeiss Jena Nr. 1647186 Triotar 1:3,5 f= 5cm
Helicoid is seen
Unknown amount of blades that formed a perfect iris

The lens is from about 1925, which would match the mount. By type, that is a common twenties focusing mount, affordable version, as I'd expect it on a "prosumer" grade SLR. However, SLRs back then were at least 6x9cm, with a long mirror, so that they fit nothing shorter than about 120mm - so that that lens must be from sth. else.
I am not aware of an affordable 35mm camera of that vintage with such a crude focusing mechanism, and a 50mm Triotar would not cover 4x6.5cm and other pre 35mm small formats. Might be a lower grade (amateur or industrial) cine lens - the focal length is right, and these cameras were wooden with flange mounted lenses back then... _________________ Sevo |

Thanks Sevo for the information.
So it is a mix and match lens with helicoid and mount. It is M39 mount. _________________ Photos and Lenses Journal
