Apple has expanded its latest smartphone lineup with the iPhone 18 Pro, iPhone 18 Pro Max and its first foldable iPhone, the iPhone Duo.
Apple unveiled the devices on September 9, 2026. The iPhone 18 Pro and iPhone 18 Pro Max became available on September 18, while the iPhone Duo is scheduled to open for preorders on October 16 before going on sale October 23.
The launch introduces significant camera and performance changes to Apple’s Pro models while giving the company a new presence in the foldable smartphone market.
iPhone 18 Pro Introduces Variable-Aperture Camera
One of the major changes to the iPhone 18 Pro lineup is its camera system.
The iPhone 18 Pro and Pro Max feature a 48MP Fusion Main camera with a variable aperture. Apple says this is the first time an iPhone has offered a physically adjustable aperture.
The system allows users to adjust the aperture to control the amount of light entering the camera and influence depth of field. Apple has also added new controls for photography and video, giving users more options beyond automatic shooting.
The Pro models are powered by Apple’s A20 Pro chip, while the Pro Max includes additional battery improvements.

| Aperture | Variable aperture |
| Processor | A20 Pro |
| Camera controls | Expanded manual controls |
| AI | Apple Intelligence features |
| Pro Max | Additional battery improvements |
| Availability | September 18, 2026 |
Apple Adds Image Provenance Technology
Apple has also introduced Apple Reference Image, a feature designed to provide additional information about the origin and capture of photographs.
The technology uses securely captured camera data and cryptographic information to create a reference for an image. Apple is positioning the feature as a way to help users establish image provenance at a time when AI-generated and manipulated content is becoming increasingly common.
However, the feature should not be interpreted as a universal guarantee that an image has never been edited or manipulated.
iPhone Duo Is Apple’s First Foldable iPhone
The iPhone Duo marks Apple’s first entry into the foldable iPhone category.
The device features a 5.4-inch outer display when closed and opens to reveal a 7.6-inch inner display. The larger screen is designed to provide more space for multitasking and content consumption.
The foldable iPhone uses Apple’s A20 Pro chip and includes a custom thermal-management system and dual-battery architecture.
Unlike the iPhone 18 Pro models, the Duo will launch later. Apple says preorders begin on October 16, 2026, with availability starting October 23.
Strong Interest Reported in China
The foldable iPhone has generated considerable interest in China ahead of its launch.
China Daily reported that the 256GB iPhone Duo had accumulated 1.29 million reservations on Apple’s JD.com self-operated flagship store as of September 17.
These figures represent reservations rather than confirmed sales. Reports of higher prices on secondary-market platforms likewise reflect individual resale activity and should not be treated as Apple’s official pricing or as a direct measure of overall demand.
iPhone 18 Pro Demand Varies Across Markets
Early reports also indicate strong interest in the iPhone 18 Pro models in some markets.
DIGITIMES reported that preorder demand for the iPhone 18 Pro and Pro Max in Taiwan was up to 20% higher than the comparable models in the previous year’s cycle.
This is a Taiwan-specific market measurement and should not be presented as evidence of global iPhone 18 Pro demand.
Apple has made the iPhone 18 Pro and Pro Max available across multiple markets, including India, China, Japan, South Korea, Taiwan, the United States and the United Kingdom.
Samsung Responds to the Foldable Competition
Apple’s arrival in the foldable market also comes as Samsung continues to promote its own foldable devices.
Yonhap reported that sales of Samsung’s Galaxy Z Fold 8 in South Korea increased by around 10% during the week following Apple’s iPhone Duo unveiling, based on telecommunications industry data.
The reported increase should be viewed as a short-term market movement. It does not by itself establish that Apple’s launch directly caused the entire increase.
Samsung has also promoted its foldable lineup through advertising campaigns in South Korea as competition in the category increases.
Foldable Smartphone Market Continues to Grow
Apple is entering the foldable segment as the overall category expands.
Counterpoint Research expects global foldable smartphone shipments to reach the 100-million cumulative milestone by the end of 2026. The research firm also forecasts 37% year-over-year growth in foldable smartphone shipments in 2027.
Despite this growth, foldables remain a relatively small part of the overall smartphone market. Apple’s entry therefore adds another major manufacturer to a category that is still developing.
How the New Apple Phones Differ
The iPhone 18 Pro and Pro Max continue Apple’s conventional smartphone design while focusing on camera, performance and software improvements. The iPhone Duo introduces a fundamentally different form factor.
| Model | Main focus | Availability |
| iPhone 18 Pro | Camera, performance and AI features | September 18, 2026 |
| iPhone 18 Pro Max | Pro features and battery improvements | September 18, 2026 |
| iPhone Duo | Foldable design and larger display | October 23, 2026 |
The different designs allow Apple to address both consumers looking for a conventional premium smartphone and those interested in a foldable form factor.
