PDMOVIE's MOTOR SMART Intelligent Focus Motor provides quick and accurate remote focus control and is equipped with smart LIDAR technology. This unit integrates its radio receiver, power supply, and motor in a self-contained package for remote focusing. Additionally, at a range of up to 16.4', the MOTOR SMART scans and tracks subjects to automatically adjust focus. This process adds an autofocus function to manual focus lenses. It can store lens travel ranges for up to five lenses for quick and seamless operation. The motor can also be controlled traditionally by pairing it with a PDMOVIE wireless controller (available separately).
