AF adapter NexusFocus F1 Dual Motors from PL to Sony E-Mount cameras

The VILTROX NexusFocus F1 Autofocus Control Adapter It is a system of adapters from Arri PL to Sony and designed to bring the autofocus driven by the camera and the electronic lens control to the cinematographic and cinemod targets with manual PL connection. Made for experienced directors, solitary operators and small crews that use Sony cameras with attack and compatible with processing AI, exploit the autofocus to the native phase detection of the camera and the subject's recognition to operate external motors for mass control Focus, diaphragm and zoom.

In narrative, commercial and documentary workflows, NexusFocus F1 allows the operation of the autofocus with classic cinematographic objectives on modern Sony cameras. Solitary operators can rely on the tracking of the camera based on the camera for interviews or work with Gimbal, while the small troupes get a repeatable and calibrated target control without a dedicated focus puller. The system is equally suitable for portable configurations, mounted on tripod or stabilized, where a precise focus are required and an opening control with minimum configuration times.

Mechanical design and power management

The NexusFocus F1 is made of aluminum alloy and stainless steel to ensure durability in production environments. Precision processing ensures a distance of the accurate flange and a reliable infinite focus.

• Dust resistant gasket on camera holder
• Anti-reflective internal thread to reduce the flare
• Removable tripod foot for a balanced equipment support
• USB-C connectivity with external power supply support adjusted via the POWER box included when using a variable or USB-C power source

Integrated display and physical checks

A backlit display on the adapter ring provides immediate access to operating mode and target data, while the touch buttons allow quick navigation in the menu without having to resort to a mobile device.

• Clearly visible in spaces with poor lighting
• Selection of the lens on the adapter and system settings

Autofocus Native Led by the camera for manual PL targets

The NexusFocus F1 adapter acts as a control hub between the camera body and external motors, translating the PDAF data and the subject recognition to Sony in accurate lens movements. Unlike Lidar-based systems, the accuracy of the focus derives directly from the camera sensor, eliminating parallax errors and maintaining a constant focus on the whole frame.

• Supports Sony Hybrid AF modes, including face and eye detection
• The transition speed of the focus and the reactivity of the AF are adjustable in the camera
• Designed for Sony cameras with attack and equipped with processor AI

Three-channel FIZ engine control

The system supports synchronized control of focus, diaphragm and zoom using external motors mounted on standard 15 mm rods. At each motor it is possible to assign a function through the integrated commands and offers a high torque with a rapid response for movie type objectives.

• Focus, diaphragm and zoom are adjustable directly from the camera interface
• Engines can also be assigned to auxiliary functions such as variable ND
• The direction and selection of functions can be configured for each engine

Calibration based on app and wireless operation

The target calibration and system configuration are managed via the VILTROX NexusFocus mobile app via Bluetooth. The adapter stores the calibration data for hundreds of objectives, allowing a rapid recall during productions.

• Automatic target calibration and preset presets management
• Preview and adjustment of parameters in real time
• Wireless focus control, diaphragm, zoom and recording from smartphone or tablet
