I have a Sony digital Handycam DCR-TRV33. Great little camera even though I haven't figured out all the features yet. On thing that amazes me is how steady it is. I attach it to my powered parachute and have got some good viedo. I wonder how the picture is kept steady and vibration free. The camera is attached to the machine's frame so it does all the rocking and rolling that the machine does. But when the tape is viewed the machine's front end is seen moving around within the picture and the camera view is mostly steady like it's sitting on gyros. What a cool feature. How do they do that?
