In olden times, a camera had one sensor, and lenses moved to magnify the picture. Now, you have several sensors and lenses, each one set to a different magnification. Where the iPhone 11 Pro’s telephoto has a “2X optical zoom” when it jumps from its wide-angle lens to its telephoto lens, the Galaxy S20 has a “10X hybrid optical zoom,” jumping from the ultrawide to the telephoto lens—the lenses themselves don’t move in either case.
