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.

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.
