What the thread found

• The Loon M1 is an analogue motor option for follow focus systems.
• The FMG motor remains available through certain distributors.
• FMG motors work reliably on video lenses and smooth, light-turning focus mechanisms but lack sufficient torque for stiff lenses.
• FMG motors deliver approximately half the power output of the M1.
• FMG motors have demonstrated durability under daily professional use over multi-year periods without requiring service.
• The M1 motor is preferred for demanding film production work due to its superior power.
• Few service providers currently support FMG motors.

Depends on

• Experience is limited to a small sample of three FMG units.
• No specifications or technical measurements provided to quantify power differences.
• The comparison between FMG and M1 is subjective rather than measured.
• Heden M28vp motors are no longer manufactured, limiting options for users of that system.
