The 15mm f/1.7 lens delivers an 84.9° field of view and bright aperture in a mere 180g body, with quiet STM autofocus and advanced coatings to suppress flare. Its compact Air series design and compatibility across Fujifilm X, Sony E, and Nikon Z mounts make it a discreet travel companion. This lens is best for street photographers and vloggers who need a fast wide-angle prime for low-light scenes and dynamic framing.
