Compatible with Sony E-mount cameras and PL-mount Cine and CineMod lenses, the Viltrox NexusFocus F1 is the first PL-E adapter to bring autofocus to manual cinema lenses.

“Focus, Reimagined”, that’s how Viltrox refers to the new solution introduced by the company, which empowers manual PL lenses with AI autofocus — control focus, aperture, and zoom via your camera, with APP-assisted auto calibration. The solution is now on Kickstarter, and already has more than 50 backers, with a total of $39,453 pledged of the $10,259 goal, and there are still 29 days before the campaign ends.

NexusFocus F1 made its first public appearance at IBC 2025, one of the world’s leading exhibitions for professional film and broadcast technology. During the show, NexusFocus attracted strong interest from cinematographers, focus pullers, and professional creators looking for a modern autofocus solution for cinema lenses.

NexusFocus F1 takes advantage of Sony’s powerful phase-detection system and AI subject recognition, and leverages those native capabilities of the camera to drive motors for aperture, focus and zoom adjustments, thus revitalizing manual lenses with powerful autofocus capabilities. Viltrox claims that “NexusFocus gives vintage lens enthusiasts, solo operators, and small film crews unprecedented creative freedom. Freed from the constraints of manual focusing and LiDAR’s parallax limitations, creators can enjoy cinematic-level imaging, with effortless control and precision.”

Viltrox notes that as “vintage lenses are making a powerful comeback” in a world were “autofocus has become the industry standard” there is a gap between them, one that NexusFocus F1 bridges, “not as a compromise — but as a translator between past and future”, the company adds, saying that “by bringing a true native autofocus control system to manual PL lenses, NexusFocus F1 unlocks a new creative dimension for filmmakers who love the character of vintage glass but demand the speed, accuracy, and reliability of modern autofocus systems.”

Here is some more information, shared by Viltrox, about the new system:

Quick set up and versatile lens control

With fast synchronized motor control of focus, iris, and zoom (FIZ), users gain complete command of every lens movement. The responsive autofocus lets solo operators and small crews work efficiently on set.

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.

Tough and compact design, with powerful performance

Compact, but with powerful performance, the motor responds with remarkable speed and precision. The standard USB type-C power port offers broad compatibility with professional equipment, and seamless connectivity. The motor is powered by an external source to ensure reliable operation. The dust-resistant seal at the camera mount end of the adapter protects equipment and preserves image integrity. The unit’s durable but lightweight aluminum alloy and stainless steel construction ensures reliability and a long operating life. A detachable tripod mount allows for flexible support.

Regarding compatibility of the system and manual control of the lenses it is paired with , some of the questions immediately asked by backers of the Kickstarter campaign, Viltrox says that “at the current stage, after installation, the product does not yet support manual control or connection to third-party devices. However, we do plan to introduce additional accessories and features to enable this functionality in the future. This is already included in our development roadmap.” The company also notes that “at the moment, the system only supports Sony cameras and does not work via other adapters” and concludes revealing that “for future solutions compatible with Nikon cameras, please follow our social media channels for the latest updates on our development progress.”

The NexusFocus F1 is now available via an official Kickstarter campaign, running until February 13, 2026.
