AI Summary

The iPhone Duo, priced at $1,999, is the most expensive iPhone ever released and essentially combines two devices in one. It retains two 48‑megapixel rear sensors—a main camera and an ultrawide that also serves for macro shots—but omits the telephoto lens and variable‑aperture system found on the iPhone 18 Pro. These omissions stem from the dual‑screen design, which limits space for additional lenses while enabling new photography tricks that use the external display. Consequently, Duo owners trade the 18 Pro’s advanced zoom capability for a higher price and a foldable‑phone experience.
