At Apple's 2026 new product announcement, the foldable iPhone Duo and the Pro/Pro Max were unveiled. The Duo starts at ¥364,800, while the 18 Pro/Pro Max feature camera capabilities comparable to those of the Pro series.
Although Apple held its annual September iPhone launch, the iPhone Duo foldable smartphone was the main focus in 2026. Meanwhile, the standard “iPhone 18 (provisional)” did not appear, with only the higher-end models announced. The article organizes the configurations and prices of each model and explains the key points to consider when choosing between them.
The iPhone Duo is a first for foldable smartphones. Its display is tall when closed and becomes wide when opened. It features an under-display camera, stylus input and Flex Mode, and is said to address areas regarded as shortcomings in other manufacturers' foldable phones. However, the user experience, including software maturity and durability, will have to be assessed through hands-on use.
The Duo's direct-sales price is clearly stated as ¥364,800 for the base configuration, prompting the view that buyers should exercise caution before purchasing immediately after launch. The iPhone 18 Pro/Pro Max, by contrast, are said to be available for less than the Duo despite their higher prices, and their enhanced camera performance is a defining feature. In particular, the variable aperture of the main camera allows exposure and white-balance adjustments, expanding the range of expression available in photos and videos.
