Design philosophy

Why I built my own ring

I tried different focus rings for years — and they all had catches. So I developed a ring that eliminates these problems.

✕The problem with other rings

Rigid PETG rings without a clamp hold inconsistently with temperature — lift the lens by the ring and it can slip off.
Rubber rings with a size range: the flexible teeth give way — on fast pulls the drive gear skips over them.
Clamp rings with grub screws against the lens fix the slipping, but quickly scratch the barrel and mount.
Many systems only fit if your lens is in their database — otherwise it gets expensive as a custom job.

✓My solution

Secure clamp mechanism with no screws on the lens — large form fit, slip-free, gentle.
Stiff, precise gear for clean mesh with the focus motor — no slipping on fast moves.
Temperature-stable ASA for reproducible clamping force and long life.
Parametric design: just ID and width — every geometry adapts automatically. Made to fit, produced fast.

Slide the ring on

Slide the ring loosely over the lens' focus ribbing.

Clamp evenly

Seat it evenly and tighten the screws with the included hex key evenly — not too tight.

Motor & backlash

Engage the motor, check backlash, turn — done.

Note: don't over-tighten — the clamp is designed to hold with moderate torque.
