Mavis Camera supports the Tilta Nucleus Nano II Hand Wheel Controller, allowing you to adjust focus, ISO and Zoom remotely without touching the iPhone.
This provides a tactile focus control for camera operators and focus pullers. It is particularly useful when the iPhone is mounted on a tripod, rig or gimbal, or positioned somewhere that is difficult to reach. Remote operation can also help prevent unwanted camera movement during focus adjustments.
What is the Nucleus Nano II?
The Tilta Nucleus Nano II is a compact wireless lens-control system. Its hand wheel provides precise, tactile control and includes a touchscreen interface for accessing its settings.
To use the hand wheel with Mavis Camera, it must be paired with the Khronos 2.4G Nucleus Wireless Receiver.
The receiver connects to the iPhone by USB-C and communicates wirelessly with the Nucleus Nano II over 2.4 GHz. This provides a reliable wireless connection for controlling focus in Mavis Camera.
