Mounting and configuration options for Arri 416 Plus camera on Steadicam

16 years old. Gear and prices may have changed since.

What the thread found

  • The camera body has a single 3/8-inch 16 screw hole at the bottom but also has locating pin holes for additional mounting options.
  • Keeping the camera's onboard battery mounted during Steadicam operation preserves the gimbal operator's battery while the camera weight remains suitable for Steadicam use under 20 pounds with a prime lens and full setup.
  • The accessory carrier can be removed and the camera body mounted directly to a Steadicam baseplate when using the lightweight support bracket, though a commercial steadicam adapter plate keeps surfaces aligned properly for secure mounting.
  • The two-piece bridge plate design allows quick-release disconnection from handheld operations by removing only the rod assembly while keeping matte box and follow focus attached.
  • A spare baseplate is the minimum additional equipment needed to enable quick switching between Steadicam and handheld configurations without requiring a spare sled or bridge plate.
  • The low mode bracket consists of two parts: a standard low mode bracket mounted to the camera and an upper handle section with spacers that keeps the Steadicam plate permanently attached while allowing the camera to flip for low mode operation.
  • Powering auxiliary equipment like a wireless video receiver from the camera's mini-monitor connector uses a single cable and works effectively without complications.
  • The lightweight support bracket with 15mm rod openings creates an uneven bottom surface that prevents direct baseplate mounting unless a dedicated Steadicam adapter plate is used to level the mounting surface.

Depends on

  • Discussion includes some disagreement about specific terminology and mounting configurations that may be rental house specific.
  • Not all rental houses may stock spare parts like additional baseplates, bridge plates, or sleds that enable the fastest configuration changes.
  • The Steadicam adapter plate mentioned is a commercial third-party accessory from a German manufacturer, not standard Arri equipment.
  • Experience shared is primarily from film production contexts rather than other camera types.
