Optical zooms offer much better quality than digital zooms. The reason is in the way the camera zooms. Optical zooms magnify as they zoom in - this means that none of the quality is lost. However digital zooms merely crop the image and then enlarge it. Therefore the number of pixels remain the same but are enlarged. The resulting image may be fuzzy or pixelated and the quality is less.
A megapixel (MP) is one million pixels. Most digital cameras have between 2MP and 5MP.
