Viltrox AF 13mm f/1.4 XF Lens for Fujifilm X in More Detail
High quality optics with superb results
The lens formula is derived of 14 elements in 11 groups which includes 4 ED and 2 HR (High Refraction) index elements, and 2 aspherical elements. The aspherical lenses are optimised for distortion and off-axis optical aberration, maintaining excellent resolution across the entire frame and across all apertures. The use of four ED (extra-low dispersion) lenses effectively improves colour fringing and provides high contrast as well as accurate colour rendition.
Well controlled distortion
A large diameter glass aspherical lens in the front group ensures that distortion is reduced as far as possible, eliminating the need for post-processing distortion correction, allowing you to create more freely with accurate results straight out of camera.
Smooth video performance
The Viltrox AF 13mm f/1.4 XF Lens effectively reduces the effects of focus breathing which can occur when changing focus during video recording. The STM focus motor is also smooth and quiet with high-speed subject tracking when paired with Fujifilm AF systems.

Our Verdict
The arrival of this compact ultra wide Viltrox AF 13mm f/1.4 XF prime lens along with the AF 75mm f/1.2 XF Pro Lens for Fujifilm X open up new creative opportunities for Fuji content creators. It is fully compatible with Fuji AF systems, with the STM focus motor keeping pace with Eye/Face and animal-detection, and makes a great choice for hybrid creators who shoot stills, videos and vlogs. Focusing is surprisingly snappy and quiet too, and Viltrox has developed the lens with minimal focus breathing, which is ideal for focus pulls and reveal shots.
The optical layout includes several special elements, which help to reduce colour fringing and aberrations, delivering high contrast, accurate and detailed results. Distortion is also extremely well controlled, with straight verticals when shooting on a flat plane, especially pleasing given the ultra wide focal length, which will inevitably be used for interiors and architectural shots.
You can handhold the lens while capturing a diverse range of wide angle subjects, gathering plenty of light from the bright aperture during low light situations, whether capturing sunset views or street scenes. With such an attractive feature list, the AF 13mm f/1.4 XF is sure to prove popular with all sorts of Fuji creators who want an affordable, versatile and highly-capable ultra wide angle lens.
