At BVE 2018, we got a closer look at the new Fujifilm XH-1 and the MK X-mount lenses.
Theo from Fujifilm shares details about where the XH-1 sits in the Fujifilm line up and who it is for.
An easy way to tell between the E-mount and X-mount versions of the lenses apart is that the X-mount has lens contacts so the camera can receive information from the lens about the focal length and aperture values it is currently at to appropriately adjust the IBIS to not vignette.
