Viltrox has announced its new AF 16mm F1.8 L, which is the company’s first autofocus lens for L-Mount systems.

This fast, full-frame L-mount lens is already available in Sony E and Nikon Z mounts.

I previously reviewed the Nikon Z-mount version of this lens, and you can see that review here.
Key features
- F1.8-F22 aperture for strong low-light performance and pleasing bokeh
- 16mm ultra-wide low distortion for landscapes and astrophotography
- STM autofocus motor delivers fast, quiet, accurate focusing
- 15 elements in 12 groups, with 4 ED and 3 aspherical elements
- Minimal focus breathing, for stable video tracking
- Durable, weather-resistant 550g full-metal construction
- Tactile, intuitive physical controls
The lens features an ultra-wide 16mm (105.6°) field of view. There are 15 lens elements in 12 groups, including 3 aspherical and 4 ED (extra-low dispersion) elements. This optical design is claimed to control distortion, chromatic aberration, and coma.

The AF 16mm F1.8 L features Viltrox’s STM stepping motor, and it is claimed to deliver fast, accurate, and stable autofocus. The lens also supports eye and face detection on compatible cameras. Focus transitions are said to be smooth and controlled, with minimal focus breathing, making the lens perfect for video production, vlogging, and hybrid shooting workflows.

The lens uses a 0.96-inch color lens info panel to show real-time data, such as a large display of current focus distance, plus depth of field, aperture, and other settings.
A Custom Function Button (Fn1) is user-assignable for quick access to frequently used settings (available functions will depend on the attached camera model). The Focus Preset Button (Fn2) instantly switches between two preset focus distances. The AF/MF Switch selects between autofocus and manual focus.
The CLICK Aperture Ring Switch selects between stepped aperture, or smooth, silent continuous aperture changes for adjustment while shooting video.
The non-bulbous front element with a 77mm filter thread supports CPL, ND, and other common filters. The high-grade dust-sealing protects the lens in demanding outdoor environments.

The Viltrox AF 16mm F1.8 L is now available for $551 USD.
