Digital zoom vs optical zoom (explained)

When you use digital zoom:

• The quality of the image gets lower. What you see is pixelated and less clear
• The quality of the recording does not change
• The zoom level of the recording does not change

When you use optical zoom (only for cameras that support optical zoom):

• The quality of the image that you see does not change
• The quality of the recording does not change
• If you use optical zoom on your camera while recording, the zoom levels used will be reflected in your recording
