HELIOS-44M-5 Repair

[Raphaelhyth]

Hey guys!
My friend just left her Zenit lens at my home and the problem with it is the following, when you turn the focus on the lens nothing happens it, it just turns around like an wedding ring on a babys finger, it has no grip and as a result it doesn't focus anything.
If anyone could help me out it would be amazing, i can also send some photos if it will help.

Welcome. Do a search on Youtube there's definitely videos on servicing the Helios lens which is a copy of the CZJ Biotar. I didn't watch these videos but saw they were there a couple od days ago.

If it's anything like the Helios 44M-4, the screws which hold the focus ring should be located under the filter ring.

By the way, for removing those "beauty rings" I've started to use these rubber cups from Japan Hobby Tool, and have been most pleased; they don't leave any marks the way a spanner wrench can:

To adjust the focus, rotate the helicoid (the brass ring under the focus ring) until the microprism screen is clear when looking at subjects beyond 10m (Infinity). Re-tighten the 4 screws, and you’re good to go.

Though there is no "vacuum" involved.
