I have a Sony Dig8 (Trv-140 E) and I like it very much, but when I make brusque movements, when filming, the images seem to be trembled. Why this happens? I have one another analogical chamber of Sony (Sony Trv-48 E) that despite the quality of the image being inferior, it does not make this. Somebody knows to say as to resolve this problem?

Thank's
