The Leak: Every Sensor in the iPhone 18 Pro Max System
A new leak has surfaced the full camera sensor lineup for the iPhone 18 Pro Max, and for the first time in iPhone history, Apple appears to be standardising on 48MP resolution across every rear camera — not just the main. Here's what the leaked spec sheet shows:
- Main (Wide): 48MP Sony IMX905 with Variable Aperture
- Ultrawide: 48MP Sony IMX972
- Telephoto: 48MP Sony IMX973
- LiDAR Scanner: Sony IMX591
- Front (TrueDepth): 12MP Sony IMX914
That's a Sony-heavy system front to back — and three brand-new sensor designations that haven't appeared in any previous iPhone. The component choices alone suggest Apple is not iterating here; it's replacing the camera stack from the ground up.
What Variable Aperture Actually Means for iPhone Photography
The headline number — 48MP across three lenses — is notable. But the detail that changes day-to-day use is the variable aperture on the Sony IMX905 main sensor.
Until now, every iPhone has shot at a fixed aperture. The wide lens on the iPhone 16 Pro Max, for instance, locks at f/1.78. That's fast enough for most scenes, but in bright sunlight it forces the camera to lean on the shutter or ISO to avoid overexposure, trading some dynamic range in the process. And in controlled lighting, a fixed aperture means a fixed depth-of-field — you get one look, and computational bokeh does the rest.
Variable aperture flips that. With the ability to physically close the iris — likely stepping between two or three discrete f-stops rather than a fully continuous range, similar to how Samsung has implemented it on the Galaxy S series — the iPhone 18 Pro Max could let photographers choose between maximum light intake and maximum depth of field without relying on software to simulate either. That's a meaningful shift for video shooters especially, where computational tricks tend to fall apart in motion.
Apple has been deliberately methodical about which features it ships and when — so the fact that variable aperture appears in a credible leak this early suggests the engineering work is further along than Apple typically reveals pre-launch.
A Closer Look at the Three New Sony Sensors
The sensor designations are worth unpacking individually, because they signal what Apple's priorities are for each lens:
Sony IMX905 (Main / Wide)
The IMX905 is a newer-generation stacked CMOS sensor in Sony's IMX9xx line, designed for high-resolution capture with improved pixel binning efficiency. Paired with variable aperture, this combination is likely targeting Apple's weakest current area: low-light video at higher zoom levels, where the fixed aperture and smaller sensor size of the telephoto have always been the bottleneck.
Sony IMX972 (Ultrawide)
Upgrading the ultrawide to 48MP — up from 12MP on the iPhone 16 Pro Max — is the single biggest resolution jump in this leak. A higher-resolution ultrawide sensor means more detail when shooting wide, better crop flexibility, and, critically, improved macro performance since Apple routes macro shots through the ultrawide lens.
Sony IMX973 (Telephoto)
A 48MP telephoto is an unusual choice. Most telephoto sensors prioritise light-gathering area over resolution, because telephoto focal lengths already sacrifice aperture. If Apple is putting 48MP behind the telephoto, the likely intent is lossless digital zoom headroom — using pixel binning at native zoom and centre-cropping at extended ranges without the quality drop that currently kicks in around 15x.
LiDAR and the Front Camera
The Sony IMX591 LiDAR designation suggests a new-generation depth scanner, likely with improved range and resolution for AR applications and low-light autofocus. Apple has leaned into LiDAR as a differentiator for pro models since the iPhone 12 Pro, and a hardware refresh here aligns with rumoured improvements to spatial video quality for Apple Vision Pro.
The 12MP Sony IMX914 front sensor holds steady in resolution — consistent with Apple's view that the selfie camera's limiting factor isn't megapixels but processing and autofocus speed. The IMX914 is a newer part than the current front sensor, suggesting improved low-light and video capabilities for FaceTime and Portrait Mode even without a resolution bump.
What This Means for iPhone 18 Buyers
The iPhone camera has always been the device's clearest differentiator. But in recent cycles, the headline improvements have been increasingly software-led — Photonic Engine, Adaptive True Tone Flash, computational macro. The iPhone 18 Pro Max leak points to something different: a genuine hardware generational shift rather than a software layer on top of familiar optics.
If the specs hold, the camera system on the iPhone 18 Pro Max would represent the most significant sensor overhaul since Apple moved from 12MP to 48MP on the main lens with the iPhone 14 Pro. That transition defined the quality gap between Pro and non-Pro iPhones for two generations. A triple-48MP system with variable aperture could set a new baseline that competitors spend the next two years catching up to — much like every tier of the mobile market is now being forced to respond to flagship camera expectations.
No official announcement has been made. Apple typically unveils new iPhones at its annual September event, which means a reveal is likely just weeks away. Until then, treat these specs as highly credible but unconfirmed.
