Focus Puller is a free app designed for iPhone users, developed by Robert Meakin. It is a multimedia tool tailored for any Blackmagic camera with Bluetooth connectivity and compatible lenses. The app offers two distinct focus control solutions: Manual Mode and LiDAR Focus Control.

In Manual Mode, users can extend the focus throw, enabling precise control similar to that of a movie camera lens. The feature includes markers and optional haptic feedback for enhanced focus control without the need to constantly monitor the image. This functionality resolves the common issue of limited focus throw when using still lenses for video recording.
