Viltrox announced a new interchangeable lens, the “Viltrox AF 14/4.0 AIR” on Friday, October 17, 2025.
The Viltrox AF 14mm F4.0 AIR is a full-frame ultra-wide-angle lens ideal for capturing majestic landscapes, architecture, and vlogs. It features an STM stepping motor for precise and quiet autofocus. The lens also supports face and eye detection, making it ideal for a wide range of applications, from photography to video.
The optical system employs an advanced design consisting of 12 elements in 9 groups (4 ED lenses, 2 high-refractive-index lenses, and 2 aspherical lenses) to effectively suppress distortion and chromatic aberration, achieving clear, high-resolution images across the entire image field. Furthermore, advanced coatings suppress flare and ghosting, even in backlit conditions, delivering crisp, clear images.
It is extremely lightweight (E-mount: approx. 170g, Z-mount: approx. 185g) and has a compact design that makes it easy to carry around. It is a lens that can be easily taken out for everything from everyday snapshots to full-scale photography.
