What the thread found

• A lightweight 3D rig can be constructed from two Panasonic DVX-100A cameras with a total weight around ten pounds, requiring a steel plate for balance on windy days.
• The DVX-100A has a fixed non-interchangeable lens with an internal focus mechanism scaled 1-99, making true follow focus challenging without modifications.
• Synchronizing focus between two cameras in a 3D rig is critical, as even subtle focus differences between cameras will compromise the 3D effect.
• Fixed focus with depth of field is preferable to attempting manual focus on both cameras simultaneously, especially outdoors with good lighting.
• One approach to controlling dual follow focus motors is using two motors on the same frequency channel with separate potentiometers, though mechanical pot variations can cause slight lens disagreement.
• Alternative 3D capture methods include positioning two cameras at different angles to create split-screen perspectives rather than true stereo imagery.
• 3D footage from compact DV cameras can be reviewed using special binocular viewers where each eye sees a separate LCD screen from each camera.

Depends on

• The DVX-100A lacks standard interchangeable lens mount needed for traditional follow focus systems.
• Synchronizing two separate motor control pots creates slight mechanical variations that may affect focus accuracy.
• The described project's final display outcome was uncertain at time of posting, as it required approval from the artist and museum installation.
• The alternative 90-degree angle approach mentioned was never broadcast in its original form due to production company decisions.
• Experience is limited to specific weather and lighting conditions (sunny, snowy outdoor shooting) with particular depth of field characteristics of 1/3 inch CCDs.
