Pick up any modern phone – be it one of the best iPhones or best Android phones – and you’re likely to find a rear panel adorned with two, three, or even four cameras. In most cases, at least one of these cameras will be an ultra-wide lens – commonly referred to as a 0.5x or 0.6x zoom, compared to the main snapper.
Apple, for example, markets the base-model iPhone 16 as having a 4x optical zoom range thanks to an inner crop on its main camera and the 0.5x “magnification” offered by the ultra-wide camera.
