1. Remove rubber from focusing ring
2. You'll see a ring comprised of two parts. Focus to closest distance (optional: for convenience only). Unscrew the front part.
3. Remove it by pulling it off.
4. You'll see three adjustment screws. They hold the focusing ring to the actual focusing helicoid. Loosen them slightly; the ring will become loose and detached from the helicoid. Adjust infinity position, tighten the screws. Assemble back.

I have the older version, full metal build, that needs to tighten these screws.
Is there a way to get access to these screws? |

I don't have the older version, but there must be some way. I would start from removing the front beauty ring (with a rubber stopper), then looking if the front barrel can be removed (usually held by a grub screw or similar). Then you would probably be able to access the adjustment screws.

The name ring is so thin, that I don't think it can fit any screws behind, but perhaps taking away the front element. |
