Next-generation iPhone 18 Pro and iPhone 18 Pro Max may at last deliver one of the highly sought after improvements to an iPhone's camera system. As per a newly emerged diagnostic log, which is said to have been obtained from an internal document belonging to Apple component manufacturer Tata Electronics, it seems likely that the next-gen Pro lineup of iPhones may come with a variable aperture primary camera.While Apple hasn't confirmed this yet, this latest leak reinforces previous months of rumours regarding the company's plans for its next-generation smartphone's cameras. If accurate, the feature would allow users to capture better photos across different lighting conditions while offering greater control over depth of field.About The AuthorJournalist and a writer with a strong interest in news, culture, technology, and human-interest stories. Passionate about making complex topics accessible and engaging.Leaked diagnostics log points to variable apertureAs per reports, the diagnostics log was uncovered amid the internal Tata Electronics files that got leaked over the internet as a result of a recent ransomware attack on the company. Researchers analysing the leaked information have reportedly come across camera calibration information pointing towards the use of a variable aperture system on the iPhone 18 Pro range.The log is said to have a calibration block that receives actuator data about the aperture mechanism of the camera from the sensor’s non-volatile memory and supports adjustable aperture settings.With variable aperture technology, the lens of the camera will be able to control the amount of light falling onto the sensor. Wide apertures would enable better photos under low lighting along with improved background blur, while small apertures would help to keep most of the scene in focus under bright lighting.Many flagships in Android smartphones have already adopted the same technology.New Sony sensor tipped for the main cameraIt is noteworthy that this leak shows that Apple will be utilizing Sony’s IMX905 sensor for the main camera sensor of the upcoming iPhone 18 Pro and iPhone 18 Pro Max.Strangely enough, according to the leaks, the pixel size of this sensor would stay the same 1.22 microns, like the previous generation.More articles by AuthorTrending StoriesThus, this might mean that the key improvement in the main camera sensor will be the variable aperture feature rather than a bigger sensor size.Most of the camera system could remain unchangedAlthough the primary camera seems to get its fair share of focus, it would appear that the other camera hardware pieces are going to stay pretty much the same.As per the information available from the leaked diagnostics log file, it has been revealed by Apple that it will use the same set of telephoto, ultra-wide, LiDAR, and front camera sensors as those present in the older generation Pro models.It has been reported that the Sony IMX973 sensor will stay as the telephoto camera’s sensor while the Sony IMX972 will be kept on for the ultra-wide camera.Price hike also rumouredApart from improvements in the camera, the new report suggests that there might be some increase in the prices of Apple's flagship smartphones.As per rumours, the prices of the iPhone 18 Pro and iPhone 18 Pro Max might go up by $200 compared to their previous versions. The price rise is allegedly due to an increase in the cost of components including memory chips, along with improvements in cameras.Launch expected in SeptemberThe iPhone 18 series is likely to make their debut in September 2026, as per their customary launch routine.The leak further hints at the possibility that the Pro variants will come alongside the alleged iPhone Ultra variant, even though no official products have been announced by Apple yet.With any leaks coming prior to the product launch, one should remain cautious till Apple validates the specifications. Nevertheless, the emergence of the diagnostics log adds weight to the well-known rumours regarding the improvements in the iPhone 18 Pro's camera.
