A leaker with a good track record on iPhone camera improvements has lent their support to a report that the 12MP front-facing camera in current iPhones will be upgraded to 24MP in the iPhone 17 line-up. They also endorse the suggestion that all three rear cameras in the iPhone 17 Pro Max will have 48MP sensors.The latest report goes a little further, however, and suggests that this years upgrade to the 5x telephoto camera sensor will apply to the iPhone 17 Pro as well as the Pro Max The iPhone 16 Pro models currently have a mix of 12MP and 48MP camera sensors:Main camera: 48MPUltrawide: 48MP (up from 12MP in the iPhone 15 Pro)Telephoto: 12MPSelfie camera: 12MPIts more than a year since Apple analyst Ming-Chi Kuo cited supply-chain sources for a planned upgrade to the front-facing selfie camera in the iPhone 17 models.The front camera of the iPhone 17 will be upgraded to 24MP/6P lens (vs. the 12MP/5P lens of iPhone 15 & 16), which will significantly improve the image quality. Genius is the primary lens supplier for iPhone front cameras.The reference to a 6P over 5P lens refers to the number of elements in the lens. All other things being equal, more elements creates a lens with fewer distortions.Kuo also indicated that the iPhone 17 Pro Max would see the telephoto camera upgraded from 12MP to 48MP.Chinese leaker Digital Chat Station endorses both reports, but indicates that both iPhone 17 Pro models will get the new telephoto sensor, not just the Pro Max.The specifications are 48Mp 1/1.3 , ultra-wide angle 48Mp, periscope 48Mp 5X, main camera and telephoto are GP glass plastic lenses, and the front camera is upgraded to 24MpThis will mean that both Pro models have 48MP sensors for all three rear cameras.Digital Chat Station has credibility where iPhone camera upgrades are concerned, having posted accurate leaks about both the telephoto lens coming to the iPhone 16 Pro and the larger sensor size in the main camera last year.Image: Michael Bower/9to5MacAdd 9to5Mac to your Google News feed.
