Viltrox AF 25mm f/1.7 Air XF Lens (FUJIFILM X, Silver)

Overview

The Viltrox AF 25mm f/1.7 Air XF Lens is a compact prime lens for FUJIFILM X-mount APS-C mirrorless cameras, offering a 37.5mm full-frame equivalent focal length that suits everyday subjects from street scenes and nature to still life. Its bright f/1.7 to f/16 aperture range, paired with a 9-blade iris, supports confident shooting in dim conditions and produces smooth, rounded bokeh that helps subjects stand out. Twelve elements in ten groups, including one extra-low dispersion, two high-refractive, and two aspherical elements, work together to control aberration and distortion for sharp, high-contrast results across the frame.

Reliable Autofocus for Photo and Video

A leadscrew-type STM motor drives quiet, precise autofocus suited to both stills and video, and focus breathing is reduced to keep transitions smooth while recording. Eye and face detection is supported on compatible camera bodies for reliable subject tracking, and electronic aperture control allows exposure to be adjusted directly from the camera body.

HD Multilayer Nano Coating

An HD multilayer nano coating on the lens elements reduces flare and ghosting in backlit scenes, helping maintain contrast and clarity even when shooting toward strong light sources.

Compact, Travel-Friendly Build

Weighing less than 7 oz, this lens keeps a FUJIFILM X kit light without sacrificing image quality, and its internal focus design means the front element does not extend or rotate while focusing.

USB-C Firmware and Exif Support

Exif data transmission and firmware updates are handled via USB-C, keeping the lens current and ensuring shooting data is recorded accurately alongside your images.

Lotus-Shaped Lens Hood

The included lotus-shaped lens hood shields the front element from stray light and knocks while shooting outdoors, complementing the lens's silver finish and travel-ready lens pouch.
