iPhone 18 Pro Max Camera Leak: What the Rumored IMX905 Sensor Could Change
Updated July 17, 2026
A reported iPhone 18 Pro Max diagnostics log may offer an early look at the camera hardware Apple is currently evaluating.
The most notable entries are a new 0x905 main-camera identifier and calibration data connected to an adjustable aperture mechanism.
Some reports have interpreted 0x905 as a possible Sony IMX905 sensor. That name has not been confirmed by Apple or Sony, and the files may describe test hardware rather than the final camera system.
For a broader look at the expected design, price and launch timeline, read our iPhone 18 Pro Max release date, price and specs guide.
Quick Answer
The leaked camera data suggests that Apple may be testing a new main sensor and variable aperture for the iPhone 18 Pro Max. The 0x905 identifier is widely being described as a possible Sony IMX905, but no official documentation confirms that product name. Several other sensor identifiers appear familiar, suggesting that Apple may be concentrating its biggest changes on the main camera.
What the Leaked Camera Log Actually Shows
Notebookcheck analyzed diagnostics information reportedly connected to internal camera-testing files that surfaced online in June.
The files appear to describe a camera configuration under evaluation for the iPhone 18 Pro Max. They do not prove that every listed component will enter mass production.
The main camera is associated with a new 0x905 identifier. The log also reportedly includes calibration information for a physical aperture actuator.
| Camera | Identifier in the Report | Likely Interpretation |
|---|---|---|
| Main | 0x905 | Possible new Sony sensor with variable aperture support |
| Ultra Wide | IMX972 | Sensor identifier may be carried over |
| Telephoto | IMX973 | Sensor identifier may be carried over |
| LiDAR | IMX591 | No obvious identifier change in the reported data |
| Front Camera | IMX914 | No obvious identifier change in the reported data |
This pattern points to a targeted main-camera update rather than an entirely new camera array.
However, sensor identifiers reveal only part of the system. Apple could still change the lenses, apertures, stabilization hardware and software used with the other cameras.

Why Is the New Sensor Being Called Sony IMX905?
The leaked data uses the identifier 0x905 rather than a complete commercial sensor name.
Reports have connected it to “IMX905” because the current-generation main camera has been associated with a 0x903 identifier and Sony’s IMX903 sensor.
That connection is plausible, but it remains an interpretation.
Sony has not released a public IMX905 specification sheet cited by these reports. Apple has also not identified the sensor planned for the iPhone 18 Pro Max.
For now, Sony IMX905 should be treated as a convenient name for the rumored component—not a confirmed retail product.
Does the Reported 1.22μm Pixel Size Tell Us Anything?
The leaked data reportedly lists an individual pixel size of 1.22μm, matching the figure Apple gives for the iPhone 17 Pro main camera.
That does not mean the sensors are identical.
Pixel pitch describes the dimensions and spacing of individual pixels. It does not reveal the total sensor area, readout speed, autofocus structure or power efficiency.
A different sensor could retain 1.22μm pixels while changing several other aspects of image capture. The leak does not provide enough verified information to measure those changes.
Why Variable Aperture Could Be the Bigger Upgrade
The iPhone 17 Pro Max uses a fixed ƒ/1.78 aperture on its main camera.
A variable-aperture camera uses a physical mechanism to make the lens opening wider or narrower. This gives the camera another way to manage incoming light before computational processing begins.
In bright conditions, a smaller opening could help the camera maintain more suitable shutter speeds and protect highlights.
It could also increase depth of field, making it easier to keep subjects at different distances in focus.
A wider aperture may improve light collection in darker scenes, but only if Apple offers an opening wider than the current ƒ/1.78 lens.
The actual aperture range remains unknown. It is therefore too early to calculate the possible improvement in night photography.
Variable Aperture Is Not New to Smartphones
Several Android flagship phones have already used adjustable-aperture systems.
The feature would still be significant for Apple because no previous iPhone has offered a physical variable aperture.
Apple would likely combine it with HDR, image stacking, noise reduction and automatic scene analysis rather than treating it as a standalone camera feature.
Why It May Matter More Than Another Resolution Increase
The iPhone 17 Pro Max already uses 48MP cameras for the main, Ultra Wide and telephoto positions.
Adding more megapixels would not automatically produce a visible improvement in normal photos.
A variable aperture could influence exposure, depth of field, shutter speed and ISO across a wider range of shooting situations.
The real value will depend on how many aperture positions are available and whether users can control them manually.
iPhone 17 Pro Max vs iPhone 18 Pro Max Camera
Current information suggests that the next camera upgrade may be more about optical flexibility than resolution.
| Feature | iPhone 17 Pro Max | iPhone 18 Pro Max — Rumored |
|---|---|---|
| Main Camera | 48MP Fusion Main | New 0x905 component, possibly called Sony IMX905 |
| Main Aperture | Fixed ƒ/1.78 | Physical variable aperture reportedly under evaluation |
| Individual Pixel Size | 1.22μm | 1.22μm in the reported diagnostics data |
| Ultra Wide | 48MP Fusion Ultra Wide | Reported IMX972 identifier may remain |
| Telephoto | 48MP Fusion Telephoto | Reported IMX973 identifier may remain |
| Status | Official Apple specifications | Unconfirmed test and supply-chain information |
The comparison does not show a clear megapixel increase. Instead, the rumored changes center on the main sensor and how the lens controls light.
That could be especially useful for outdoor video, close-range photography and scenes with difficult contrast.
Camera hardware is only one part of the upgrade decision. Our full iPhone 17 Pro Max vs iPhone 18 Pro Max comparison also covers expected battery life, design changes, performance and whether current owners should wait.
Could the Other iPhone 18 Pro Max Cameras Still Improve?
Yes. A familiar sensor identifier does not mean Apple will reuse the complete camera module without changes.
The same sensor could be paired with revised lens elements, a larger aperture, better stabilization or a different autofocus system.
Separate reports have suggested that the telephoto camera may receive a larger aperture. That would not conflict with the IMX973 identifier because the lens and sensor are separate components.
Apple could also improve image quality through a newer image signal processor and updated computational-photography algorithms.
The current evidence therefore supports “possibly unchanged sensors,” not “unchanged cameras.”
How Reliable Is This Camera Rumor?
Variable aperture has been mentioned by several analysts and supply-chain reports, making it one of the more persistent iPhone 18 Pro camera rumors.
The newly reported aperture-calibration data is consistent with those earlier claims.
The Sony IMX905 name is less certain because it depends mainly on how the 0x905 identifier has been interpreted.
Multiple technology websites have repeated the information, but most coverage traces back to the same diagnostics data rather than separate hardware inspections.
Repetition across several outlets should not be mistaken for multiple independent confirmations.
What remains unknown: The final sensor name, sensor dimensions, aperture range, number of aperture positions, manual controls and real-world image-quality improvements.
Should You Wait for the iPhone 18 Pro Max Camera?
Waiting may be worthwhile for photographers, video creators and people upgrading from an older iPhone.
A variable aperture could provide more flexibility than the fixed lens used in current models, particularly during video recording and challenging lighting.
Current iPhone 17 Pro Max owners should wait for official camera samples and independent comparisons.
A new sensor identifier does not guarantee a major improvement in normal daylight photos, and the practical value will depend on Apple’s software and aperture controls.
Buyers who are waiting for confirmed specifications should also follow our latest iPhone 18 Pro Max rumors and release timeline, which will be updated as new information becomes available.
FAQ
Is Sony IMX905 confirmed for the iPhone 18 Pro Max?
No. The name is based on the reported 0x905 identifier. Apple and Sony have not confirmed an IMX905 sensor.
Will the iPhone 18 Pro Max use a larger main sensor?
That is not known. The identifier and 1.22μm pixel pitch do not reveal the complete dimensions of the sensor.
Will variable aperture improve low-light photography?
It may, but only if the maximum aperture is wider than the iPhone 17 Pro Max’s ƒ/1.78 opening. The final range has not been reported reliably.
Will every iPhone 18 Pro Max camera be upgraded?
The leaked identifiers suggest that several sensors may remain familiar. Apple could still update their lenses, stabilization, autofocus and image processing.
Could it beat the next Samsung Galaxy Ultra camera?
It is too early to make that comparison. Final retail hardware and controlled photo and video testing will be required.
When is the iPhone 18 Pro Max expected to launch?
Apple has not announced a release date. Current expectations point to the usual fall 2026 launch period for the Pro models, but exact dates remain unconfirmed.
Bottom Line
The newly reported diagnostics log provides a more detailed picture of the camera system Apple may be testing for the iPhone 18 Pro Max.
Its most important clues are a new 0x905 main-camera identifier and data connected to a variable-aperture mechanism.
The evidence does not confirm a retail Sony IMX905 sensor or final production specifications.
For now, the most reasonable conclusion is that Apple may be preparing a more adaptable main camera rather than redesigning every part of the camera array.
