What the thread found

• A BFD follow focus system failed to power on after being stored in a vehicle at minus 7 degrees Celsius for about five hours, but functioned normally again after returning to room temperature.
• The M-One motor performed reliably under the same cold conditions.
• One user reported successful operation of a BFD in Russian winter conditions.
• Cold-related failures in BFD systems may be traced to specific components with temperature-dependent malfunction, and the manufacturer may be able to identify and repair such issues.

Depends on

• Only one incident documented at minus 7 degrees Celsius; the user notes that Norwegian winters can reach minus 20 degrees or colder.
• A power connection issue via alternative connectors was suggested as a possible cause but not confirmed.
• The exact age of the affected unit and whether the power failure was caused by battery contact problems, component failure, or another mechanism remains unclear.
