Clearly either Samyang screwed up the communications protocol to the camera, there is a lens F/W bug or the lens has a H/W issue. If the camera will use IBIS with A/F lenses and with M/F lenses then the issue is with the lens. Return it.

What Truman said, but before doing so, I’d love to see some 1/2 and 1 second images that are tack sharp. It would enlighten me to the IBIS capabilities of the X-S10.

I've just shot some samples to show the difference and maybe show what to expect from the X-S10's IBIS at 12mm. Everything hand-held of course.

First three images are shot with the new Samyang AF 12mm F2 X. IBIS turned on, but obviously not working:

Next three images are shot with the old Samyang MF 12mm F2. As the lens has no contacts, I had to manually enter lens name and focal length in the menu. IBIS again turned on, leading to clearly better results:

I do admit, that "tack sharp" might be exaggerated when looking at 100% view. However the difference between IBIS and no IBIS should be obvious.
