What the thread found

• The Bartech and Preston systems are regarded as leading wireless follow focus options for cinema applications.
• Preston systems support three channels and command a higher price point, while Bartech operates as a single-channel device that can be linked for additional channels at the cost of increased handset bulk.
• The Bartech system can be paired with the M1 motor from Palomar Engineering to provide high-torque focus control on difficult lenses.
• The M1 motor delivers sufficient torque to rotate most lens types, but excessive power can cause equipment flex and motor binding when used with heavy optical systems like the Pro 35 setup.
• Palomar Engineering offers motors with varying torque levels, including the M-0.5, to accommodate different lens weights and prevent over-torque issues.
• The Stanton Jimmy Jib provides zoom and focus control for HD lenses on steadicam setups and includes adjustable creep compensation.
• Both Bartech and Preston manufacturers are noted for responsive customer support.
• Extremely high motor torque can damage sensitive lens mechanisms, as demonstrated by cases where equipment flexed or lens mounts were damaged during focus calibration.

Depends on

• The discussion dates from 2007 and may not reflect current product availability or specifications.
• Recommendations regarding motor selection appear based on individual user experience rather than comprehensive comparative testing.
• The specific suitability of these systems for Canon and Fujinon HD lenses mentioned in the original question is not directly addressed.
• The thread contains incomplete information about the M-0.5 motor, which was apparently unreleased at the time of discussion.
