22 years old. Gear and prices may have changed since.

The Benz 5100 operates on frequencies around 915MHz with approximately 10 available channels and features auto-calibration and auto-seek functions to reduce assistant camera workload during lens changes.
The Benz 5100 uses TNC-style antenna connectors and plastic locking rings for lens marking, with pricing for receivers ranging from $1000 to $2000 depending on channel configuration and handsets priced around $1050.
The Benz 5100 is compatible with M-one motors, Heden motors, FMG motors, and older CP sled motors, with zoom control available for specific motor types.
The BFD system uses RP-SMA antenna connectors rather than BNC/TNC connectors to comply with FCC Part 15 regulations, which restrict antenna types that could be easily replaced with higher-gain alternatives.
The Benz 5100 offers flexibility for operators working with both film and video packages by allowing configuration of multiple system components on an à la carte basis.
The Benz 5100 is primarily useful for cinematographers and crane operators needing integrated control over multiple functions, whereas the BFD is simpler and more established for basic focus pulling on Steadicam rigs.
Service and technical support reliability is critical for follow focus systems, particularly when equipment fails or requires modifications in the field.

Very few Benz 5100 units had reportedly shipped by 2004, with long wait times reported by some buyers.
The Benz 5100's service quality and response times are uncertain for users outside the UK, though a US distributor was available.
The discussion does not establish definitive performance comparison data between the two systems under identical conditions.
Antenna design philosophy differs between systems due to regulatory constraints, which may affect practical field performance but is not fully explored.
