It’s true that Apple had a hard time changing, but last year we finally left behind the 12-megapixel sensor to welcome a 48-megapixel sensor, present in both the iPhone 14 Pro and the iPhone 14 Pro Max. This year we won’t see too much new there, except in the Pro Max model.
The latest rumors from the Apple world indicate that the iPhone 15 Pro Max will feature a more advanced camera sensor than the iPhone 15 Pro. The user Ice Universe has been who has echoed the leak on Twitter and proclaims that the sensor that will mount the iPhone 15 Pro Max would be different and much larger.
This new sensor, the IMX903, will be 1/1.14-inch in size. According to the figures, it will be larger than the IMX803 (1/1.28 inches), the sensor that incorporates the two iPhone 14 Pro currently. In addition, leaks also speak that we will have the possibility of capturing in 14-bit DNG RAW at the hardware level.
On the other hand, Apple will reserve this improvement exclusively for the iPhone 15 Pro Max, since the iPhone 15 Pro seems to keep the same IMX803 as its predecessors.
The iPhone 15 Pro Max will feature a periscopic camera.

The improvements in the iPhone 15 Pro Max camera are not just about the sensor. Not long ago, we also learned that these models will exclusively incorporate a periscopic camera. Thanks to this lens, we will be able to make more optical zoom (it will not lose quality) and it would go from the 2X we currently have to 5X. Will the camera of the future iPhone 15 Pro be able to compete against those of terminals such as the Samsung Galaxy S23 or the Google Pixel 7 Pro?
