I was testing out spotlight mode locking onto a stationary subject. My only stick input was either hard left or hard right. I am pretty sure I was not pushing forward or backward on the stick. I expected it to do a perfect circle around the subject. As you can see it moves further away from the subject as it circles. I took the image as it was in the first circle with the stick hard left. As you can see the second circle with the stick hard right has an even more exaggerated movement away from the subject.
