Viltrox is addressing one of the long standing compromises in digital cinematography with the introduction of NexusFocus, a new autofocus solution engineered specifically for manual lenses.
As high resolution sensors, AI assisted subject tracking, and fast paced solo production workflows continue to evolve, many filmmakers have been forced to choose between the character of vintage and cine glass and the efficiency of modern autofocus systems.
The NexusFocus F1 aims to bridge that gap by integrating directly between the lens and camera body, transforming manual optics into electronically driven tools that fully leverage Sony’s phase detection autofocus and AI recognition technologies, without sacrificing the optical identity that makes these lenses desirable.

At the heart of the system is the NexusFocus F1, a compact and lightweight adapter designed to sit unobtrusively between the lens and camera.
The adapter is compatible with Sony E mount cameras and PL mount Cine and CineMod lenses, opening the door for a wide range of professional and legacy optics to gain modern autofocus functionality.
By tapping directly into the camera’s native autofocus engine, NexusFocus drives motors for focus, iris, and zoom control, effectively revitalizing manual lenses with intelligent automation.
NexusFocus is positioned for vintage lens enthusiasts, solo operators, and small production teams seeking greater creative freedom without complex setups.

By eliminating the need for manual focus pulling or LiDAR based systems that can introduce parallax limitations, the system allows creators to maintain cinematic precision while simplifying on set operation.
Setup and operation are designed to be fast and intuitive. With synchronized motor control across focus, iris, and zoom, users gain precise command over every lens movement.
Responsive autofocus performance enables efficient shooting in dynamic environments, particularly for single operator productions where speed and reliability are critical.
Configuration and calibration are handled through the Viltrox NexusFocus mobile app.
The app offers a selection of ready to use lens calibration profiles and automatically detects calibration status on startup, allowing users to mount the adapter, power on, and begin shooting with minimal preparation.
Automatic calibration is currently supported on the iOS version of the app. Bluetooth connectivity enables wireless control via smartphones and iPads, giving creators greater flexibility in camera placement and remote operation.

The adapter also features a clear backlit status display on its top surface, providing instant visibility into operating modes and lens data.
This built in display reduces reliance on external monitors or mobile devices during production.
Despite its compact form, the NexusFocus F1 delivers strong performance.
The internal motor is engineered for speed and precision, while power is supplied through a standard USB type C port connected to an external source for consistent and reliable operation.

A dust resistant seal at the camera mount helps protect equipment and maintain image integrity in demanding environments.
Constructed from aluminum alloy and stainless steel, the adapter balances durability with portability for long term professional use.
A detachable tripod mount is included, allowing for flexible support options when building out camera rigs.
Viltrox plans to release the NexusFocus F1 through an official Kickstarter campaign running from January 15 to February 13, 2026.
Feature availability and performance may vary depending on camera and lens combinations, and users are encouraged to consult the campaign page for full compatibility details.
