MoonStorm
This camera suffers from a design flaw or a firmware bug that manifests itself when zooming out while recording a video. The moment you stopped using the zoom switch, the camera automatically zooms in a bit causing a jerky recording. The problem doesnt occur when zooming in, nor does it occur when the image is zoomed all the way out while recording. Sony was made aware of the problem on their official support site, however were still waiting for an acknowledgment of the issue and most importantly for a fix.
