Why do cell phones have multiple cameras?

Modern smartphones, like the iPhone 15 Pro, feature multiple cameras to improve the quality and versatility of mobile photography and videography. Each camera has specific features that allow users to capture different types of images and videos with greater detail and accuracy.

Features of each camera on the iPhone 15 Pro

main camera

The main camera of the iPhone 15 Pro is a 48 MP wide-angle camera with an aperture of ƒ/1.78. This camera is ideal for most general photography situations, providing excellent image quality and superior low-light performance thanks to the Photonic Engine and Deep Fusion.

ultra wide angle camera

The ultra-wide-angle camera has 12 MP and an aperture of ƒ/2.2. It’s perfect for capturing wide landscapes, large group photos, and architectural shots, offering a much wider field of view than the main camera.

Telephoto camera

The iPhone 15 Pro’s 12MP Telephoto camera features a ƒ/2.8 aperture. This camera allows users to zoom in up to 3x optically, perfect for getting closer to distant objects without losing quality. This is especially useful for portrait and detail photography at a distance.

TrueDepth front camera

The 12MP TrueDepth front camera with ƒ/1.9 aperture is not only essential for selfies, but also enables Face ID facial recognition and supports advanced features like Portrait mode, Animoji and Memoji.
