Apple rarely reveals future hardware before launch. This time, an alleged supplier leak may have done it instead.
A newly surfaced diagnostics log, reportedly recovered from internal Tata Electronics files leaked by the World Leaks ransomware group, appears to reveal several camera details for Apple’s upcoming iPhone 18 Pro Max ahead of its expected September launch.
According to Notebookcheck, the log shows Apple replacing the iPhone 17 Pro Max’s main camera sensor with Sony’s IMX905. While the sensor keeps the same 1.22-micron pixel size as its predecessor, the documents indicate the biggest change is support for a mechanical variable aperture rather than a larger sensor.
The diagnostics log reportedly includes calibration data tied to the aperture actuator, which Notebookcheck reported confirms the hardware support for the feature. The diagnostics log reinforces earlier rumors that both the iPhone 18 Pro and iPhone 18 Pro Max will feature a variable-aperture main camera, TechRepublic previously reported.
Most of the camera system appears unchanged
Beyond the new primary sensor, the leak suggests Apple’s camera hardware will look very familiar.
According to the leaked documents, the telephoto camera will continue using Sony’s IMX973 sensor, while the ultrawide camera, LiDAR receiver, and front-facing camera also remain unchanged from the iPhone 17 Pro Max. Multiple reports say this means Apple’s imaging improvements may rely more on the new main camera and software processing than a complete hardware overhaul.
If accurate, that means Apple’s biggest camera upgrade this year would focus on improving the main camera’s flexibility rather than refreshing the entire imaging system.
What variable aperture could mean
Variable aperture allows a camera to physically adjust how much light enters the lens by changing the opening size. Unlike software-generated background blur, the feature can provide more natural depth-of-field effects while also helping photographers adapt to different lighting conditions.
The technology has appeared on several flagship Android phones in recent years, but Apple has yet to introduce it on an iPhone.

Price questions remain
Variable aperture lenses aren’t cheap to build. Component prices for them have jumped roughly 50% this year, according to Neowin, and that’s landing right as memory chip costs are also climbing. Retail projections suggest Apple may raise the price of the Pro Max by an average of $200.
Looking ahead
If the leaked diagnostics log is genuine, it suggests Apple is prioritizing image quality improvements through a more advanced main camera rather than redesigning the entire camera system.
That approach could benefit users who shoot in a wide range of lighting conditions, but it may leave owners of recent Pro models questioning whether the upgrade is significant enough, especially if higher prices accompany relatively modest hardware changes elsewhere.
Apple is expected to unveil the iPhone 18 lineup in September, when the company will either validate or contradict these leaked specifications. Until then, the diagnostics log offers one of the clearest looks yet at Apple’s camera plans—but, like all pre-release leaks, it should be treated as unconfirmed.
