Yay...I got that right , because I was going to say what Michelle said.But just did not know that ratio.Be quick, be smooth and the arm you hold your camera in, use as a pivot tight to your body with camera held firm on your flattened palm.That is what a photographer taught me years ago and it works great. But if you are panning it si kind of hard to hold tight in to your body so then be smooth. Now if I could only get the focus right all the time.
