Viltrox AF 25mm f/1.7 for Fuji X

The Viltrox AF 25mm f/1.7 for Fuji X is a lightweight prime lens designed to make everyday photography more enjoyable, flexible, and accessible. With a compact build, fast autofocus, and a bright f/1.7 aperture, it delivers strong image quality in a form factor that’s easy to carry wherever inspiration takes you.

Its 25mm focal length offers a natural perspective that sits comfortably between standard and wide-angle, making it a versatile choice for street photography, portraits with context, indoor scenes, still life, and travel. The lens is also well suited for video, with smooth focus transitions and support for in-body image stabilization on compatible cameras.

Thanks to the quiet STM motor, autofocus is fast and accurate while remaining discreet during shooting. Eye and face detection support is available on compatible camera bodies, helping you track subjects with confidence in both photos and video. The bright aperture also makes it easier to shoot in lower light and create a soft, pleasing background blur.

Advanced multi-layer coating helps improve light transmission and reduce reflections, supporting clear, contrast-rich results. The 9-blade aperture contributes to smooth, rounded bokeh for a more polished and creative look.
