What the thread found

• The Arri lightweight follow focus can be used on older Zeiss high-speed lenses because its smaller geared ring fits inside the PL-mount locking handles where a larger motor cannot be positioned
• A spacer (dog bone) with 15mm holes can extend a motor away from lightweight support rods, allowing it to be repositioned further back toward the lens gear
• One of the two screws holding a PL-mount locking handle can be removed to create additional clearance for a follow focus gear
• A free-drive gear can be used as an alternative solution

Depends on

• The solution applies specifically to Arri SR cameras with Mk1 Zeiss standard lenses featuring locking handles
• Some suggested solutions were not fully tested or confirmed in the thread
• The exact compatibility with different motor models and lens combinations was not comprehensively documented
