What the thread found

• The M1 motor produces more noise than the Heden M28VP, but users consistently reported no practical problems on actual productions.
• Motor noise from the M1 becomes noticeable primarily during high-speed focus rack moves, which occur less frequently than slow creeping moves where motor sound is most critical.
• Sound department personnel on professional sets determined the M1 motor noise was acceptable compared to camera operating noise.
• Users reported no complaints about M1 motor noise across multiple film productions over extended periods of use.
• The M1 features snap-on pitch gears and versatile rigging options, though some operators found mounting more complex than Preston motor systems with PAM brackets.

Depends on

• The noise assessment is based on professional film production environments, not controlled laboratory conditions.
• Most noise feedback came from operators already committed to the M1 system.
• One operator expressed preference for the Preston PAM bracket mounting system over the M1 approach.
• The discussion does not provide objective noise measurements beyond anecdotal reports.
