What is the difference between electronic, digital, and optical image stabilization?
Electronic and digital image stabilization both use electronic processing to reduce shakiness and blur after the image has been captured. Similar to digital zoom, digital image stabilization reduces image quality by producing a pixelated, grainy-looking image. When choosing a camcorder, you should look for one that uses optical image stabilization. It combats camera shake by actually shifting the lens elements during filming, and produces a cleaner looking video.
