Focus Gear for Rokinon/Samyang 8mm F2.8 UMC FISH EYE II E-Mount Lens

For Housings with 80mm Bayonet | Polycarbonate

The Focus Gear for Rokinon/Samyang 8mm F2.8 UMC FISH EYE II E-Mount Lens allows precise manual focus control in underwater housings. It attaches to the lens focus ring and is operated via the housing's external focus dial.

How It Works:

  1. Engages the Lens Focus Ring — The focus gear, a ridged or toothed ring, attaches to the lens focus ring.
  2. Interfaces with Housing Controls — The housing has an external dial that meshes with the focus gear.
  3. Allows Manual Focus Adjustments — By turning the external control, the diver can manually adjust the lens focus.

Why It's Important:

  • Allows fine-tuned focus adjustments in low-light or high-turbidity conditions.
  • Useful for video shooters who need precise focus control.
  • Works with Dome ports.
  • Helps when using dome ports where focus distance may be affected by the water-air interface.
