Updated July 17, 2026
A leaked ISP diagnostics log analyzed by Notebookcheck suggests Apple may be testing a new main-camera system for the iPhone 18 Pro Max.
The log references a 0x905 camera identifier and calibration data related to a variable-aperture actuator. Reports have linked this identifier to a possible Sony IMX905 sensor, although Apple and Sony have not confirmed the details.

Quick Answer
The latest iPhone 18 Pro Max camera leak suggests Apple may introduce a new main-camera component and variable aperture technology. The 0x905 identifier has been interpreted as a possible Sony IMX905 sensor, but the final hardware, specifications and image-quality improvements remain unconfirmed.
What Does the iPhone 18 Pro Max Camera Leak Reveal?
Notebookcheck reported that the diagnostics data came from internal camera-testing files that appeared online in June.
The information appears to describe a camera configuration Apple may be evaluating for the iPhone 18 Pro Max. However, testing hardware does not guarantee that the same setup will appear in the final retail model.
| Camera Component | Reported Identifier | Possible Meaning |
|---|---|---|
| Main Camera | 0x905 | Interpreted as possible Sony IMX905 with variable aperture |
| Ultra Wide | IMX972 | Identifier reportedly unchanged |
| Telephoto | IMX973 | Identifier reportedly unchanged |
| LiDAR | IMX591 | Identifier reportedly unchanged |
| Front Camera | IMX914 | Identifier reportedly unchanged |
The leak suggests Apple may be focusing on improving the main camera rather than replacing every camera component.
Does 0x905 Confirm a Sony IMX905 Sensor?
No. The identifier suggests Apple may be testing a different main-camera component, but it does not independently confirm the commercial sensor name.
The name IMX905 is inferred from the leaked 0x905 identifier and the reported connection between the previous 0x903 identifier and Sony's IMX903 sensor.
No public Sony documentation cited in the reports confirms an IMX905 product name. Until Apple or Sony publishes official information, IMX905 should be treated as a rumored identifier rather than a confirmed specification.
The reported 1.22μm pixel size also does not mean the sensor will be identical to the current generation. Pixel size only describes individual pixels, not the complete sensor design.
Apple could still change sensor area, readout speed, autofocus performance, power efficiency or dynamic range. The leaked data does not confirm improvements in these areas.
What Would Variable Aperture Change?
The iPhone 17 Pro Max uses a fixed ƒ/1.78 main-camera aperture. A variable-aperture system adds a physical mechanism that changes the lens opening to control incoming light.
In bright conditions, a smaller aperture could help manage exposure, protect highlights and increase depth of field. In darker scenes, a wider aperture could allow more light to enter if it exceeds the current ƒ/1.78 opening.
The final aperture range is still unknown, so specific improvements in night photography cannot yet be confirmed.
Unlike software-based processing, variable aperture changes the optical characteristics before the image reaches Apple's computational photography system.
Variable-aperture cameras already exist on several Android flagship phones. If Apple adopts the technology on iPhone 18 Pro models, it would be a first for Apple's smartphone lineup, but not for the smartphone industry.
Why Variable Aperture May Matter More Than More Megapixels
Apple already uses 48MP cameras across the main, Ultra Wide and telephoto cameras on the iPhone 17 Pro Max. A future upgrade may focus less on resolution and more on improving how the camera controls light.
A variable aperture could affect exposure, depth of field and video flexibility in ways that a higher megapixel count may not provide.
iPhone 17 Pro Max vs iPhone 18 Pro Max Camera
The rumored iPhone 18 Pro Max camera upgrade appears to focus on optical improvements rather than simply increasing megapixels.
| Feature | iPhone 17 Pro Max | iPhone 18 Pro Max |
|---|---|---|
| Main Camera | 48MP Fusion Main Camera | 0x905 sensor, interpreted as Sony IMX905 |
| Aperture | Fixed ƒ/1.78 | Variable aperture reportedly being tested |
| Pixel Size | 1.22μm | 1.22μm reported in leaked data |
| Ultra Wide | 48MP Fusion Ultra Wide | IMX972 identifier reportedly unchanged |
| Telephoto | 48MP Fusion Telephoto | IMX973 identifier reportedly unchanged |
| Status | Official | Rumored |
Even if some sensor identifiers remain unchanged, Apple could still improve lenses, stabilization, autofocus and image processing. The current leaks point toward a focused main-camera upgrade rather than a complete camera redesign.

Could the Other iPhone 18 Pro Max Cameras Still Improve?
Yes. An unchanged sensor identifier does not necessarily mean the complete camera system remains unchanged.
Apple could improve other camera components, including the lens design, aperture, autofocus system, stabilization and image processing.
For example, a telephoto camera could receive a wider aperture without changing the underlying sensor. The reported IMX973 identifier alone cannot reveal whether optical improvements are being tested.
Camera performance also depends heavily on Apple's computational photography system, including image processing, HDR algorithms and AI-based enhancements.

How Reliable Is This iPhone 18 Pro Max Camera Rumor?
The variable-aperture camera rumor appears to be one of the more consistently reported iPhone 18 Pro camera upgrades.
Supply-chain reports and analyst predictions have suggested Apple is working on a variable-aperture main camera, making this feature more credible than many early rumors.
However, the Sony IMX905 claim is based mainly on the interpretation of the leaked 0x905 identifier.
Multiple websites reporting the same information does not necessarily mean multiple independent confirmations. Most coverage appears to trace back to the same leaked diagnostics data.
Important: The leaked log may reveal a camera configuration Apple is testing, but it does not confirm the final iPhone 18 Pro Max hardware.
Should You Wait for the iPhone 18 Pro Max Camera?
The iPhone 18 Pro Max could be worth waiting for if you are a photographer, video creator or currently using an older iPhone model.
The rumored variable aperture system could provide more flexibility in challenging lighting conditions, especially for video and professional-style photography.
However, current iPhone 17 Pro Max owners should wait for official camera samples before upgrading.
A new sensor identifier or camera technology does not automatically guarantee a major improvement in everyday photos.
FAQ
Is Sony IMX905 confirmed for the iPhone 18 Pro Max?
No. The IMX905 name is an interpretation of the leaked 0x905 identifier. Apple and Sony have not officially confirmed this sensor.
Will the iPhone 18 Pro Max have a larger camera sensor?
That remains unknown. The leaked identifier and reported 1.22μm pixel size do not reveal the complete sensor dimensions.
A sensor can keep the same pixel pitch while changing in physical size, readout performance or image quality characteristics.
Will variable aperture improve iPhone night photography?
It could, but the improvement depends on the final aperture range.
If Apple provides a wider maximum aperture than the current ƒ/1.78 lens, the main camera may capture more light in certain situations.
Will the iPhone 18 Pro Max camera beat Galaxy Ultra phones?
It is too early to know.
Apple appears to be focusing on the combination of sensor hardware, variable aperture and computational photography rather than simply increasing sensor size.
A fair comparison will require final retail hardware and independent camera testing.
When will the iPhone 18 Pro Max launch?
Apple has not officially announced the iPhone 18 Pro Max.
Current reports suggest the Pro models could launch in fall 2026, following Apple's traditional release schedule, but the exact date remains unconfirmed.

Bottom Line
The latest iPhone 18 Pro Max camera leak provides more technical details about Apple's possible next-generation camera system.
The leaked diagnostics data points to a new 0x905 main-camera identifier and calibration information related to a variable-aperture mechanism.
However, the Sony IMX905 name, final aperture range, sensor size and real-world image improvements remain unconfirmed.
For now, the evidence suggests Apple may be testing a more flexible main camera rather than simply adding more megapixels.
