Zoom Lens (n.) A lens with a variable focal length, allowing the photographer to change the magnification of the image without moving. In mobile photography, true optical zoom lenses are relatively rare due to space constraints. Instead, many smartphones use multiple fixed lenses at different focal lengths or employ computational techniques to simulate zoom. Understanding the difference between optical, digital, and hybrid zoom can help mobile photographers make informed decisions about framing and image quality when capturing distant subjects.
