Viltrox AF AF 13/1.4 XF
An f/1.4 max aperture and 20mm equivalent view make this 455g lens a low-light standout, with an STM motor delivering silent, focus-breathing-free video AF down to 8.7 inches. Its optical design—two aspherical and four ED elements—yields sharp images and smooth bokeh at a budget price, though weather sealing is absent. It’s best for Z-mount APS-C videographers needing a fast ultra-wide for vlogging and run-and-gun shoots.
About This Lens
Ideal for landscapes, cityscapes, street scenes, architecture, and more, the Viltrox AF 13mm f/1.4 XF is a sleek ultra-wide prime lens characterized by its portability, advanced optical design, and intuitive handling. Its fast f/1.4 maximum aperture balances size and speed and is suitable for working in available lighting conditions. It offers greater control over depth of field and provides a soft bokeh effect at wider apertures while also limiting the overall size and weight of the lens for everyday use. Designed for smooth video capture, the lens effectively eliminates focus breathing when changing focusing distances while shooting video, and an STM autofocus motor provides fast and responsive AF down to a minimum object distance of just 8.7".
