and here are the mounts; OEM on the left, Adaptist on the right:
once installed, it will be obvious but the Adaptist mount is about 1 - 2mm smaller in diameter than the OEM mount:
I suspect that since the KS-1 was manufactured after the Adaptist mount, there was never any trials/fittings for the mount on this model of body, hence the gap....
all the holes for screws, lens lock, electronic sensors, and the autofocus drive match up perfectly and the five screws tighten down just like they should....
