Designed to bring the advantages of Sony’s powerful phase-detection system to existing manual focus lenses, the compact NexusFocus F1 adapter fits unobtrusively in between the lens and the camera body.

The system is compatible with Sony E-mount cameras and PL-mount Cine and CineMod lenses and enables the camera’s controls to drive motors for aperture, focus and zoom adjustments, thereby giving manual lenses powerful autofocus capabilities. Ideal for vintage lens enthusiasts, solo operators and small film crews it also gives users access to Sony’s AI-based subject recognition focusing modes and allows them to enjoy cinematic-level imaging. The Viltrox NexusFocus mobile app allows for effortless setup, with a wide range of lens calibration profiles ready-to-go. The system automatically detects calibration status on startup, so users can just mount the adapter, power on and start creating (automatic calibration is currently only available on the iOS app version). The app also provides Bluetooth wireless control with smartphones and iPads, allowing limitless camera placement options and versatile single-user operation. The adapter features a clear backlit status display panel on top, so users can instantly check the operating mode and lens data.
The NexusFocus F1 is currently available via an official Kickstarter campaign, which runs from January 15 to February 13, 2026. Click here for full details.
