iPhone 15 Pro/Pro Max now supports new telephoto, ultra-wide, and wide lenses, with the sensor-shift stabilization, which is available on iPhone 15 Pro only. There is also 3x optical zoom in and 15x digital zoom to record subjects closely without loss of detail. The wider apertures on iPhone 15 improve the low-light performance by “up to 92% improvement in low light” according to Apple.

The new Cinematic mode allows for a rack focus effect to intelligently shift the focus from one subject to another. Now you can easily create beautiful depth effects and focus transitions with iPhone 15, that’s what iPhone 15 can’t do. The new Photographic Styles applies local edits to an image in real-time as the photo is rendered. And you can record videos in ProRes in 4K 30fps on the iPhone 15 Pro.
