Iphone 18 pro camera gets a thickening makeover – and a variable aperture boost
Apple’s gearing up for the iPhone 18 Pro and Pro Max, alongside the rumored foldable Ultra, and early leaks are already hinting at significant camera upgrades. But it’s not just about megapixels; a recent Weibo post from Fixed Focus Digital reveals some surprising changes to the rear camera module – specifically, a 2mm increase in thickness.
Thickness isn’t always a bad thing: apple’s camera gamble
The increase, according to the leak, is directly linked to an “Enlarged main camera module,” suggesting Apple is investing heavily in improving the image-capturing capabilities of the flagship models. This isn’t a minor adjustment; it’s a noticeable shift, and one that begs the question: why?

Variable aperture: a dslr-inspired move
But the thickening isn’t the only intriguing detail. Fixed Focus Digital also points to the implementation of a variable aperture system – a feature previously seen on Huawei’s Mate 50 Pro. This Technology, mimicking DSLR functionality, allows the camera to dynamically adjust the aperture (f-stop) based on lighting conditions. In bright light, the blades close, minimizing light intake and preventing overexposure. Conversely, in low-light scenarios, the blades open, maximizing light capture and reducing noise.

Samsung followed suit years ago
It’s worth noting that Huawei pioneered this approach back in 2022 with the Mate 50 Pro, utilizing a multi-stop variable aperture system (f/1.4, f/2.0, f/2.8, f/4.0). Samsung also experimented with dual-aperture systems on the Galaxy S9 and S9+ in 2018, switching between f/1.5 and f/2.4 depending on the environment. Apple's move represents another step toward refining mobile photography – a field where they’ve consistently pushed boundaries.
The a20 pro and 2nm tech
Beyond the camera, the iPhone 18 Pro series is slated to be the first to utilize Apple's new 2nm process node, built by TSMC, and incorporate Gate-All-Around (GAA) transistor architecture. This promises a significant performance boost, potentially delivering a 15% increase in CPU speed compared to the A19 Pro chipset. It’s a clear signal that Apple is doubling down on cutting-edge Technology, but this time, it’s wrapped in a slightly thicker package.
Looking ahead: iphone 18e and air 2
While the Pro models are generating the most buzz, Apple’s also expected to release the iPhone 18, 18e, and Air 2 next spring. However, the 18 Pro’s utilization of the 2nm process means this advancement will initially be exclusive to the premium offerings. Ultimately, it’s a calculated risk – a gamble on image quality and processing power that could reshape the smartphone landscape.
