****YES, it is the newer MARK II. X-T30 and X-T30 II have absolutely no differences in the body, only internal differences. The "II" does not appear on the front of the body. You can only tell by looking at the grey tag at the bottom of the camera that it is mark II (last picture of the listing)****
Camera is like new. I have barely used it (shutter count: 155 actuations).
Body Only. I do not have the original box anymore, but it comes with the original battery, strap and micro USB to USB A cable (everything that comes with it in the box).
