• Dual-camera stereoscopic steadicam setups for 3D filming using F35 or F23 cameras with Pace gear can weigh approximately 70 pounds on the arm alone, approaching or maxing out the capacity of professional steadicam arms like the Pro Arm and G70.
• The weight distribution in 3D rigs is unconventional because the vertical camera placement puts mass below the gimbal, creating unusual balance characteristics that differ from standard steadicam operation.
• Heavy 3D steadicam rigs require significant counterbalancing using batteries and weights mounted on extended aluminum plates at the rear of the sled, sometimes requiring structural bracing.
• Operational limitations of heavy 3D steadicam packages include inability to perform quick rig rotations of 90 degrees or more due to gimbal interference, restricted running capability, difficulty with stair climbing, and increased vibration transmission through the rig.
• Switchovers between different camera configurations are extremely difficult on heavy dual-camera steadicam rigs due to the overall mass and complexity of the setup.
• Modified short posts can be maintained on heavy 3D rigs by placing substantial rear counterweight, avoiding the need for the extended posts required on other configurations.

• Discussion focuses primarily on Pace steadicam 3D rigs and may not apply to other manufacturers' systems.
• The specific film shooting in Vegas had minimal prep time, which limited assessment of the actual rig configuration.
• Some disagreement exists about whether the 70-pound figure includes or excludes the sled and additional components, though technical details from experienced operators suggest it represents camera and immediate mounting hardware.
• Experience was primarily with F35 and F23 cameras; applicability to other camera models is unclear.
