Problem with close focus modding Iscorama Pre 36

[Steven]

I have reading some descriptions of successful close focus mods of the iscorama 36 and tried the same method with my pre 36.

I did remove the front ring with the iscorama inscription and serial number on it with the help of a drinking glas and hotglue.

After that step removing the four screws underneath should release the plastic ring with the focus scale on it, but it doesnt move at all.

I tried to applie mild force but it stayed where it was. Tried google and forum search but I couldn't find any actual description of a pre 36 mod.

Can anyone help?

I actually solved the problem. I did not apply enough force when I tried it the first time. I applied two reduction rings to the filter thread of the focus ring and was able to pull it off.

I think it's better to mark the focusring's position on the inside before pulling it off, so finding infinity when reassembling is easier.

 

I did not apply the actual mod yet because I want to install a new stopper after 360 degree rotation, but it turned out to be harder than I thought.
