Hello,
Anyone know anything about this I-10? I received it today.
No factory logo, it has little helicoide, diaphragm and it came with kind of UV filter.
I guess process lens, or enlarger, but I never seen it before.
Regards,
Pierre |

Hello Pierre,
it is not I-10, but some lens for special needs (f.E. some scientific devices).
I think there is exact model-code on it, s.picture 3: ...10K2...
Could you please post here photo with the whole code on this ring?
Regards, Alexander |

It's interesting that the focal length '50' is written before the aperature '3,5'. That's how Americans would name lenses. Europeans are used to the opposite.
Also the focal length is meant in 'mm' which could say something about it's age.
For example, younger Jupiter-11 are marked '4/135', focal length in 'mm' too, but the aperature is in front. |

I think the order of 50 and 3.5 is more about the fact that it's reproduction lens. Also not that marking looks to down, like on most of repro or enlarger lenses.
Yes, mm and design of the lens itself tells us that it is from 70's or even 80's.
But I don't know the apparatus that was wearing it. We can see that the lens was fixed to camera with 4 screws. The ring where is written everything is the diaph ring. Hélicoïde is moving by moving the screw on rear side, so the focus were done on camera side.
And this weird filter... |
