Motor torque and speed for vintage anamorphic lenses in cold weather
12 years old. Gear and prices may have changed since.
What the thread found
- Motor torque depends not only on the motor itself but also on how much current the motor driver can supply.
- The DM1 and DM2 models offer more torque than the DM1X, though they operate at slower speeds.
- Vintage anamorphic lenses can become extremely stiff in freezing conditions and may not rotate even with motorized follow focus systems.
- Analog motor systems like Bartech with an SLD100 motor can serve as backup when powered motorized systems struggle with cold temperatures.
- Extremely stiff lenses can be difficult to turn manually, indicating the mechanical resistance exceeds what some motor systems can overcome.
Depends on
- No published torque or speed specifications were found for the M-One Digital motor.
- The discussion involves only one anecdotal account of cold-weather motor failure with specific vintage anamorphic lenses.
- The actual specifications and capabilities of the M-One Digital motor remain undocumented in the thread.
- Cold temperature performance data applies to one particular job context and may not generalize to all conditions.
