upcoming iPhone 18 Pro may differ from their predecessors thanks to a new camera feature that could be exclusive to the larger Pro Max model. This information comes from a Chinese leaker and has sparked intense interest in the tech analyst and user community, as it suggests a significant differentiation in the iPhone lineup, which could influence consumers' purchasing decisions.

Since 2024, we've been hearing rumors about Apple's plans to introduce a variable aperture camera to the iPhone 18 Pro - a first for an iPhone - but until now it was thought that the feature would come to both devices. Variable aperture is a technology that allows the lens to adjust its aperture, thus providing greater flexibility in taking photos in different lighting conditions.
This feature is common in professional DSLR cameras, but has not been implemented in Apple smartphones so far.
Leaker Ice Universe claims that this is not the case. The iPhone 18 Pro Max will feature “exclusively variable aperture.” This development suggests that Apple may be looking to differentiate the two Pro models based on camera capabilities, which could significantly impact the market.

iPhone 18 Pro Max: Previous leak suggested variable aperture
We already know that a variable aperture lens is coming to the iPhone 18 Pro Max, thanks to internal files leaked by Apple supplier Tata Electronicsin June. The files revealed that the iPhone 18 Pro Max will feature a new Sony IMX905 sensor with variable aperture support. This sensor is expected to offer improved low-light performance and greater flexibility in creative photography.
The smaller iPhone 18 Pro model wasn't mentioned in the leak, but it wasn't clear whether that meant it wouldn't get a variable aperture lens or if the files simply didn't include that information. The lack of this feature on the smaller model could affect its popularity among consumers looking for top-notch photography capabilities.

An innovation for Apple
Apple has never implemented a variable aperture on an iPhone. From the iPhone 14 Pro to the iPhone 17 Pro, the main camera uses a fixed aperture of ƒ/1.78, which means the lens remains fully open at all times when taking pictures. This limits the possibilities for adjusting exposure and depth of field, something that a variable aperture could greatly improve.
With a variable aperture, the iPhone 18 Pro Max could allow users to manually change the aperture, similar to a DSLR camera. This could mean more control over depth of field, allowing for sharper focus on subjects or smoother background. It all depends on how Apple implements the feature, of course. It could be more automated than that.
This feature could offer users the ability to adjust their photos with greater precision, enhancing the user experience.

The iPhone 18 Pro Max is rumored to be larger and heavier than its predecessor. Aside from the rumored bezel, it is expected to be on par with its smaller sibling. Both iPhone 18 Pro models are expected to launch next month alongside Apple’s first foldable iPhone , the “iPhone Ultra.” This launch is expected to generate a lot of interest, as consumers will have the opportunity to choose between different technological innovations that Apple offers.
