Powering 35mm film cameras on a 12V steadicam rig designed for video cameras

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

What the thread found

  • The only 35mm camera that can be powered from an onboard battery on a 24V-capable steadicam is the 235 model.
  • Most other 35mm cameras require either a belt battery with a power cable running to the camera, or a separate block battery system.
  • A 12V to 24V converter can power a 24V camera but drains batteries significantly faster, requiring more battery capacity.
  • Using a shoulder-mounted belt battery with a cable tethered to the camera is practical but adds weight and bulk to the rig, complicating operation.
  • Operating with cable power requires an assistant to manage the line, which is not ideal but possible on set.
  • Film cameras and 35mm equipment quickly approach or exceed the weight limits of rigs designed for smaller video cameras, requiring careful validation before shooting.
  • Testing the complete camera and accessory combination on the rig before a production day is essential.
  • Follow focus systems typically require their own power supply and add to the complexity of the setup.

Depends on

  • The discussion focuses on 35mm film cameras and a Provid steadicam rig, both technologies and equipment from the mid-2000s era.
  • No detailed technical specifications about the 12V to 24V converter's efficiency or battery drain rate are provided.
  • The feasibility of specific 35mm camera models on the Provid is not exhaustively tested or documented in the thread.
  • One participant suggests conducting personal research rather than relying on forum recommendations for final camera selection decisions.
