iPhone 17 Pro Max, designed from the inside out to be the most powerful iPhone models ever made. At the core of the new design is a heat-forged aluminum unibody enclosure that maximizes performance, battery capacity, and durability. Across the iPhone 17 Pro camera system, you’ll find innovation that goes to great lengths. The telephoto features the next generation of our tetraprism design and a 56 percent larger sensor. With an equivalent 200 mm focal length, the 8x optical-quality zoom makes this the longest iPhone Telephoto ever — offering 16x total optical zoom range. So you can explore an even wider range of creative choices and add a longer reach to your compositions.
