Compact Ultra-wide Angle Lens: This 13mm ultra-wide-angle lens is designed for APS-C-format Nikon Z-mount mirrorless cameras. The compact lens design and versatility can meet the different needs of photographers and video users, easy to carry and operate. | Large Aperture: Bright f/1.4 maximum aperture suits working in low-light conditions and also affords greater control over depth of field. This lens is autofocus, with manual focus override. The aperture is also manually adjustable with an aperture ring based on the lens body, from F/1.4 to F/16 in 1/3 stops with A mode. | Excellent Optical Design: 14 elements in 11 groups, 4 ED glass, 2 aspherical lenses, and 2 high refraction index lenses, which can effectively suppress colour difference and control spherical aberrations. | STM stepping motor: The SMT stepping motor enables quick, quiet, and precise autofocus performance along with a full-time manual focus override. Additionally, an internal focusing design maintains the overall lens length during use for improved handling and quicker response. | EXIF Data Readable: All EXIF data is recorded so you know you were using this lens, the aperture you were shooting at and all other relevant information as if you were using a native lens.
