Just recently, while filming anything that requires zooming in (mainly aircraft is what I'm using it for), I am getting a side-to-side violent shaking on the image. It is making the camcorder completely un-usable and completely ruining all footage. I don't use a tripod or anything, and I generally have a steady hand, so it's definately not me shaking (it still shakes when I put it on the floor and am not touching it). Please see the attached youtube link of the sort of film I am getting (some of it is over-zoomed just to emphasise the issue). Does anybody have any ideas as to the best course of action, or for any cures?
Any help would be very much appreciated!
