Jupiter 3 optical part into an industar 50 mount

[Gianfranco_R]

do you think is this possible? I've found a jupiter 3 but only the optical part... so non focusing mount... in what focusing mount I can place it? I've got some industar 50 at home... would it fit? please help!

Hello Gianfranco,

I think that your optical part from a Jupiter-3 could be mounted in a Jupiter-3 mount only...

A fine lens. I have it in Kiev/Contax mount and it always gives excellent results.

Best wishes,

It will not fit in an I-50 or J-8 mount, the rear section is just too big.

Ciao Gianfranco, I have clad a Jupiter 3 lens a couple of weeks ago and and industar 26 some days before... Thay are different, J3 has 2 differend threaded coaxial helix for the focus, instead of the Industar has only 1... In the Industar I cannot remove the optical part as I did for the J3...
I am not a master of FSU lenses but in my opinion it is not possible... The best thing to do is to open ebay and search for an old, scratched J3...

Regards

On the I-26, the construction is about the same as the I-61.

This thread shows how to take out and move the optical section in the focus mount:

Thank you Brian for the link to the I-26 dismounting... but fortunately my lens focuses well and I don't need to remove the optics...
