A qualitative leap in iPhone photography
In the smartphone world, the camera has become the primary battleground between companies. After years of incremental improvements, Apple appears to be planning a giant leap. According to a new report from Korean outlet ETNews, along with confirmations from trusted analyst Ming-Chi Kuo, the iPhone 18 Pro and iPhone 18 Pro Max models will feature a massive main camera upgrade: variable aperture technology.
This feature, if successfully implemented, could represent the biggest evolution in the iPhone camera in years, giving professional and amateur users alike a new level of creative control.
What is variable aperture and why does it matter?
In photography, the aperture is an opening inside the lens that can be widened or narrowed to control the amount of light reaching the camera sensor. Most smartphone cameras, including all current iPhone devices, have a fixed aperture. For example, the iPhone 17 Pro main camera has a fixed aperture at ƒ/1.78, meaning it is always open to the same degree.
Variable aperture, as the name implies, allows the camera to dynamically adjust the size of this opening. This opens up a world of possibilities previously limited to professional cameras (DSLR and mirrorless).
How will users benefit from this technology?
Variable aperture comes with two main benefits:
- Light control: In dark environments, the aperture can be opened to its widest setting to allow the maximum amount of light in, resulting in brighter, clearer photos with less noise. In very bright environments (like a sunny day at the beach), the aperture can be narrowed to prevent over-exposure and preserve details in highlight areas.
- Depth of field control: This is the most exciting feature for photographers. A wide aperture (small f-number) creates a shallow depth of field, meaning the subject is sharply in focus while the background is beautifully blurred (the bokeh effect). A narrow aperture (large f-number) creates a deep depth of field, making everything in the photo, from foreground to background, sharp and clear, which is ideal for landscape photography. Currently, the iPhone simulates this effect via software through “Portrait” mode, but variable aperture will allow it to be achieved optically, resulting in a more natural and accurate effect.
Technical challenge: Why did Samsung abandon it?
Apple is not the first to try this technology. Samsung introduced a variable aperture camera in its Galaxy S9 and S10 phones in 2018 and 2019. However, it abandoned it in 2020. The main reasons were that the mechanical mechanism required to change the aperture increases the thickness and cost of the camera module, which conflicts with the constant pursuit of making phones thinner and lighter.
The challenge facing Apple is to develop a compact and efficient mechanism that does not significantly impact the phone’s design or price. The company appears confident in its ability to achieve this.
Supply chain details: Apple’s plans move forward
The ETNews report indicates that Apple is already moving forward with its plans and discussing components with suppliers. The variable camera module is expected to be manufactured by LG Innotech and Foxconn, while the actuator controlling the mechanism will be manufactured by Chinese companies Luxshare ICT and Sunny Optical.
The future of the iPhone: Camera first
The iPhone 18 Pro and Pro Max are expected to be announced in the fall of 2026, alongside the iPhone Air 2 and Apple’s first foldable phone. The focus on a major camera upgrade in this generation shows that Apple still views photography as one of the most important key selling points for its flagship devices.
A game changer in 2026
If Apple successfully integrates variable aperture into the iPhone 18 Pro, it will be a true game changer. It will give professional photographers a more powerful and flexible tool, while allowing average users to capture better photos in a wider range of conditions. It is an upgrade worth waiting for.
FAQs
Q: Which models will get the new feature?
A: According to leaks, the feature will be exclusive to the iPhone 18 Pro and iPhone 18 Pro Max models only.
Q: What is the difference between variable aperture and the current Portrait mode?
A: The current Portrait mode uses software to simulate a blurred background. Variable aperture achieves this effect optically by controlling the lens itself, resulting in more natural and accurate results.
Q: When is the iPhone 18 Pro expected to launch?
A: In the fall of 2026.
