If you ever used HDR or panorama stitching software, you know "motion correction" is known as "de-ghosting". Zero difference.

And across HDR softwares the results differed as well as it is all about the algorithm and there are better ones and worse ones. I had good impression with Photomatix.

And surely the K-3II had a working motion correction in it that worked for rapidly moving subjects.

Now with the current DCU version where you can choose to switch it on or not afterwards I think it is not worthwile to even think about it at shooting time.
