Types of zoom


What is a digital zoom?

Digital zoom requires no focal adjustment on your camera, making these less of a hassle and bringing down camera prices. This zoom takes the existing recorded images and expand them. You lose none of your camera’s recordings even after zooming in.


What is a optical zoom?

Optical zoom has adjustable focal lenses, allowing for crisp detail when zooming into the scene. This zoom crops out the rest of the scene, which is particularly helpful when only focusing on one area. You will lose no detail when zooming in.
