Hardware required:
Part | Qty | Size | Purpose |
|---|---|---|---|
Grub screws | 2 | M3 × 6 mm | Keep focus ring centered in groove |
Stop screws | 2 | M3 × 12 mm | Engage slot to prevent barrel rotation |
Silicone Grease | Optional for focus ring thread lubrication |
The grub screws should NOT be fully tightened
adjust them just enough so the focus ring rotates freely but cannot slide.
