Sorry 'bout that! It has taken a while to find two clips that illustrate the difference in sharpness that were (sort of) comparable in light level and included motion.
The first clip (Slender Filefish) was taken at 1/60 and the second (Turtle head) at 1/125. I just included a still capture from each because the difference to me is the same as seen in the clip. Here they are:

I had to reduce the image sizes to upload the files, trying to preserve the level of detail; these are close, but the IQ of each did suffer in the reduction of file size.
I hope the IQ carries through enough to let you see the difference.
