Assess the type and amount of zoom the digital camera features. Digital camera zoom is expressed in both optical and digital measurements. The optical zoom is the more important of the two, as it represents how much the camera will enlarge an object while still maintaining clarity. Digital zoom will take over after the optical zoom reaches its limit, but the more you digitally zoom in on an object, the less clear and sharp it becomes. The zoom of a camera is measured in terms of how many times larger the camera will enlarge an object. For example, a 3x zoom will make an image appear three times larger than the original image appears.
