Extendable mid-arm swivel for steadicam to achieve extreme high and low camera angles without extending the center post

What the thread found

  • The device allows camera height adjustment of up to 12 inches above or below the standard position by swapping interchangeable post lengths without changing the main center post, avoiding performance degradation from extended center posts.
  • Using longer arm posts to achieve extreme angles can cause arm bending or failure when lifting cameras 5 or more inches, whereas the swivel provides safer vertical displacement.
  • The swivel maintains the same arm performance and handling feel as a standard configuration because it only relocates where the midarm block connects rather than changing the arm's structural properties.
  • Changing between the three interchangeable post lengths takes 15 seconds to one minute per swap, allowing quick transitions between high and low mode shots during production.
  • The device does not require pushing down on the arm to achieve low mode shots, reducing fatigue and improving operator movement freedom compared to manual arm depression techniques.
  • Extreme high angle shots become feasible without loss of control or steadiness, extending the practical range of shots achievable in a single setup.
  • The product is currently compatible only with the Pro arm model due to cost and complexity of adapting the asymmetrical design to other arm architectures.

Depends on

  • Only compatible with Pro arm models currently; adaptation to other arm types would require asymmetrical redesign at significantly higher manufacturing costs.
  • Interchangeable post lengths provided are 2.8 inches, 6 inches, and 12 inches, limiting flexibility to these discrete height adjustments rather than continuous variation.
  • Physical hand reach limits how low the camera can be positioned in low mode regardless of post length available.
  • Some operators questioned whether the device charges extra rental fees to customers, with sparse information available on standard pricing practices.
