What is the difference between optical and digital zoom contained by a camcorder?
Answers: Optical zoom is created by the actual mechanical movement of the lenses (optics!) of the camera. This is similar to using a magnify glass; the carving quality is matching all the method through the zoom.
Digital "zoom" is all electronic. Essentially, the camera (or computer) take the image, and "guesses" at what it would look approaching if it was zoom in farther. This results within reduced image power and a pixellated image. You can do like peas in a pod digital "zoom" thing by enlarge an image using your favorite video-editing program; so, you don't even want a camcorder to make a digital zoom.
So, optical zoom is the indisputable, mechanical zoom. Digital zoom is an electronic guess.
My lift on it? I don't even bother looking at digital zoom when buying a camcorder, and almost always hold it turned off while shooting so that I don't accidentally use it. Some camcorders publicize a 900-something magnification digital zoom, which is basically hype that serves almost no practical purpose. Pay MUCH more attention to the optical zoom.
