Summary

The Viltrox AF 15mm f/1.7 Air is an ultra-lightweight, fast wide-angle prime lens designed specifically for APS-C mirrorless cameras across Fujifilm X, Sony E, and Nikon Z mounts. Developed by Viltrox as a core addition to its portable Air series, it weighs just 180 grams and provides a 35mm equivalent focal length of approximately 22.5mm, delivering a broad, immersive field of view tailored for street photography, architecture, landscape captures, travel adventures, and daily vlogging.

Its sophisticated optical construction comprises 12 elements in 10 groups, featuring three Extra-low Dispersion (ED) elements, three High Refractive Index (HR) elements, and two precision aspherical lenses. This advanced optical layout maintains high resolving power and crisp contrast across the entire frame, effectively suppressing chromatic aberrations, color fringing, and optical distortion. Furthermore, the specialized HD multi-layer nano coating reduces ghosting and flare when shooting against strong light sources.

Autofocus is driven by a silent STM stepping motor paired with an internal focusing mechanism that ensures smooth, responsive subject tracking for both high-resolution stills and video production without shifting the barrel length. With a close minimum focusing distance of 0.23 meters and a bright f/1.7 maximum aperture, the lens excels in dim lighting conditions and produces pleasing background blur with dynamic wide-angle subject separation.
