Zhong Yi Optics has launched the Mitakon Speedmaster 65mm F1.4 for Fujifilm GFX cameras. This announcement makes Zhong Yi Optics the first third-party manufacturer to develop a lens for Fujifilm's G mount and gives them the claim — for the time being — of having the fastest standard lens designed specifically for GFX medium format mirrorless camera systems.

The lens provides a 46-degree angle of view, roughly equivalent to a 50mm lens on a 35mm full-frame camera. It's constructed of eleven elements in seven groups and has a minimum focusing distance of 70cm.

The Mitakon Speedmaster 65mm F1.4 features an aperture range of F1.4 through F16 via its nine-blade aperture diaphragm. The front filter thread measures in at 72mm and the whole lens weighs 1,050g.
