Viltrox's first X-mount AF lens, launched in October 2018 alongside the E-mount PFU RBMH 85mm F1.8 and 20mm F1.8. The launch spec sheet calls it a full-frame autofocus prime and lists internal focusing, a 1:8 maximum ratio, M72×0.75 filter, 80 mm diameter and 636 g. Later sold as the AF 85mm F1.8 XF and replaced by the AF 85mm F1.8 II XF. Not on Viltrox's current store or firmware download list; no source states it as discontinued, so status is not stored.
