What the thread found

• The Bartech BFD follow focus system was inspired by the Chrosziel Fox, which was an expensive existing product, and was designed to achieve similar functionality at a lower cost.
• The BFD began shipping in 1999 and has sold over 2300 units with continued monthly sales of 20 or more units.
• A competitor's follow focus system called the VFX existed but the BFD developer did not encounter one in person until 2001, when a customer showed them a broken unit.
• The Chrosziel Fox is no longer repairable as a product, while the BFD continues to be manufactured and serviced.

Depends on

• The discussion centers on disputed historical claims about who developed what and when, with conflicting accounts about the timing of events and interactions between parties.
• Only secondhand reports are provided about the other follow focus systems and competing claims.
• This represents one perspective in a documented disagreement about the product's origins.
