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.
