Samyang released its first lens for the Fujifilm APS-C sensor system at the end of 2021 - the Samyang AF 12mm f/2 at the end of 2021. And as usual with Samyang lenses, this is being sold under the Rokinon brand in North America.
The new Samyang 75mm f/1.8 X, however, seems to be a completely new design for the system, in that it doesn't look currently available in any other mount. As it is not made for full-frame sensors, it is very obviously different from the existing Sony-mount Samyang AF 75mm f/1.8 FE.
Names: Samyang AF 75mm f/1.8 X / Rokinon AF 75mm f/1.8 X

Full frame: Yes
Image stabilization: No
Lens construction: 10 elements in 9 groups

Diaphragm blades: 9
Minimum aperture: f/22
Minimum focusing distance: 0.69m

The Fujifilm version will have an equivalent focal length of 112.5mm, due to the 1.5x crop factor used by the X-mount camera range.
The lens is actually slightly heavier and bigger than the Sony version, weighing in it at 257g. But again uses 10 elements in nine groups, with nine aperture blades.
The lens will sell for $499/£475.
