13mm · f/1.4
The Viltrox AF 13mm F1.4 is a well-regarded ultra-wide APS-C lens offering a 19.5mm full-frame equivalent. It delivers sharp center performance wide open, with good edge sharpness stopped down, though vignetting is noticeable at f/1.4. Optical corrections are improved over previous Viltrox lenses, but flare resistance is poor, with colorful artifacts and reflections. Build quality is solid with metal construction and a smooth aperture ring. Autofocus is fast, silent, and reliable. It suits landscape, architecture, and low-light shooters seeking a fast, affordable wide prime, but not for flare-critical work.
