Balancing and tuning a GH1 camera on a Merlin gimbal for stable operation
15 years old. Gear and prices may have changed since.
What the thread found
- A GH1 with 14mm pancake lens weighs approximately 480-500 grams, which is light enough to cause swaying and instability on the gimbal.
- Using heavier lenses (800-1000 grams combined weight) produces more satisfactory results because increased mass improves stability.
- Adding mass away from the gimbal increases rotational inertia, which improves stabilization performance.
- A hotshoe microphone positioned at distance from the gimbal can provide meaningful additional stabilization due to its mass placement away from the pivot point.
- Camera support rails can add mass and help lift the camera, increasing rotational inertia for better performance.
- Adding a plate to lift the camera and spread mass distribution can improve stability and facilitate transitions to stick or handheld operation.
- Rotational inertia depends on the square of the mass times the distance from the gimbal, so placing weight further away has a significant effect.
- The compact camera body results in lower rotational inertia compared to longer video camera designs.
Depends on
- Advice based on experience with GH1 camera and Merlin gimbal from 2011.
- The original poster was still learning gimbal operation, so some instability may have been due to handling technique rather than setup alone.
- No specific weight recommendations provided for accessories to add.
- Discussion includes theoretical physics explanations that were not fully verified by testing in the thread.
