Viltrox AF 13mm f/1.4 XF STM ASPH ED IF Autofocus APS-C Lens for Fujifilm X-Mount, Black Review

The Viltrox AF 13mm f/1.4 XF is an ultra-wide autofocus prime for Fujifilm X-mount APS-C cameras, offering a 20mm full-frame equivalent field of view. With a fast f/1.4 maximum aperture, it targets landscape, architecture, and astrophotography shooters who need both width and light-gathering power. The lens includes ED glass elements and aspherical optics to manage distortion and chromatic aberration, and uses an STM motor for autofocus.

At $411, it undercuts first-party Fujifilm ultra-wides by a considerable margin, positioning itself as a budget-conscious alternative. Viltrox has built a reputation for delivering solid optical performance at accessible prices, though build quality and autofocus consistency can trail premium offerings. The inclusion of a lens hood and 67mm filter thread adds practical value for field use. For Fuji shooters seeking an affordable ultra-wide with a bright aperture, this lens fills a clear niche.
