Big Breakthrough: The mystery behind Apple's iPhone 15 Pro Max's unique camera technology

Jon McCormack, Apple’s vice president of camera software engineering, explained in detail in a recent interview why the four-prism lens module on the iPhone 15 Pro Max only has 5x optical zoom, rather than pursuing a higher magnification zoom

McCormack said that the telephoto lens of iPhone 15 Pro Max not only increases the zoom factor, but also achieves a huge leap in camera technology. This phone uses unique four-prism lens technology to increase the optical zoom of the telephoto camera from 3x to 5x, and expand the maximum zoom to 25x. This technological innovation is not only a numerical increase, but also a qualitative improvement in the shooting experience

According to the editor’s understanding, iPhone 15 Pro The telephoto lens on the Max integrates optical image stabilization and an autofocus 3D sensor shift module, making it Apple's most advanced camera stabilization system yet. This means that even at high zoom levels, users can still easily take stable photos with reduced blur and shake.

Compared to other mobile phone manufacturers that may pursue higher magnification telephoto lenses, Apple pays more attention to the stability of photos. McCormack pointed out: "We think 5x zoom is the best solution at this stage to ensure stable photos, and you can look at 10x zoom, which is really difficult to use unless you have the steadiest hands in the world or a tripod."

In addition, the 5x telephoto lens used by the iPhone 15 Pro Max has an aperture of f/2.8, while the competing Samsung Galaxy S23 The Ultra's 10x telephoto lens has an aperture of f/4.9. A wider aperture means more light can enter the camera sensor, which is great for night photography and shooting in low-light conditions. This further improves the iPhone 15 Pro Max’s performance in different shooting scenarios.
