2 x Optical Zoom
Zoom lenses operate with many glass elements that are moved into different arrangements as you push the zoom button. Changing the space between glass elements changes the focal length. This system is called optical zoom because the focal length is changed using the actual glass lens elements. A 16:1 zoom will bring objects 16 times closer than what you'd normally see.
3 x Optical Zoom

4 x Digital Zoom
Digital Zoom increases the standard (optical) zoom by 2x, 4x or even 12x. This is done by digital memory and thus a very high zoom may cause unwanted grain or noise to appear. Digital zoom function can be switched off if necessary.
