The camera equipment manufacturer Viltrox has launched an Indiegogo (founded) campaign for the Viltrox 13mm f/1.4, a large-aperture ultra-wide-angle autofocus lens that is perfect for vlogging, landscape, architecture, street, food, and astrophotography. Earlier this year, Viltrox launched a 13mm f/1.4 autofocus lens for Fujifilm X-mount camera systems. Now, Viltrox is back with the launch of a crowdfunding campaign to bring this lens to Nikon Z and Sony E-mount APS-C camera systems (or their respective full-frame cameras used in crop mode).

Generally, the aperture of an ultra-wide-angle lens is relatively small, but the VILTROX AF 13mm f/1.4 lens consists of both 13mm ultra-wide-angle and f/1.4 large aperture at the same time. The large aperture design greatly improves the amount of light and shutter speed, which can be used in low light. The lens, which offers a full-frame equivalent 20mm focal length, is constructed of 14 elements in 11 groups, including two aspherical elements, four extra-low dispersion (ED) elements, and two high-refractive index elements. It features an internal focusing unit driven by a stepping motor, has a minimum focusing distance of 22cm, uses a nine-blade aperture diaphragm, and uses a 67mm front filter thread.
