For the past two years, the variable aperture has been considered the camera highlight of the upcoming Pro generation – for both Pro models. A new report from China calls this into question: only the largest and heaviest device is said to have it. This would mean that choosing the Pro Max would once again be a question of camera quality, not screen size.
Leaker Ice Universe wrote on Weibo that the variable aperture will remain exclusive to the iPhone 18 Pro Max. Previously, all reports assumed that both Pro models would receive the technology – see the overview of all rumors surrounding the iPhone 18 Pro.
Key Facts at a Glance
- According to a Weibo post, the variable aperture will only be available in the iPhone 18 Pro Max.
- The technology for the Pro Max is already confirmed by leaked supplier documents from June, which mention a Sony sensor IMX905.
- The smaller iPhone 18 Pro was missing a corresponding entry in these documents – whether as an exclusion or as a gap, remained unclear.
- Apple has never used a variable aperture in iPhones before; since the iPhone 14 Pro, the main camera has been fixed at ƒ/1.78.
- A division based on model size would not be new: The iPhone 15 Pro lacked the tetraprism telephoto lens, which only the Max model received.
What the article claims
The gist of it is a single sentence: the variable aperture is exclusive to the iPhone 18 Pro Max. This is accompanied by a sarcastic remark that even Apple can't escape the rule that the best camera is only found in the heaviest device.
A variable aperture allows you to change the lens opening, just like on a DSLR camera. In practical terms, this means more control over the depth of field, i.e., how much the background blurs. It remains to be seen how much of this control Apple gives the user and how much happens automatically.
How reliable is the source?
Ice Universe primarily operates in the Android community and only occasionally comments on Apple products, but when he does, his predictions are often spot on. Before the iPhone 17 Pro Max, he stated a thickness of 8.725 millimeters – Apple delivered 8.75 millimeters. Most recently, he showed protective films for the foldable model that confirmed the asymmetrical corners of the iPhone Ultra.
The second piece of evidence is stronger. In June, internal files from Apple supplier Tata Electronics surfaced, listing a Sony IMX905 sensor with variable aperture support for the iPhone 18 Pro Max. These documents originated from a cyberattack on Tata. They contained no such entry for the smaller Pro model – however, this doesn't necessarily rule it out, as it's unclear how complete the documents were.
Two years of reports that said something different
The variable aperture has been a recurring theme in the reporting on the iPhone 18 Pro since November 2024, and until now, the Pro models have always been referred to in the plural.
| Date | Status of the report |
|---|---|
| November 8, 2024 | First reports of a camera upgrade with variable aperture |
| February 23, 2026 | Technical details about the new camera are becoming more concrete. |
| April 16, 2026 | Production of the aperture modules is starting. |
| August 18, 2026 | For the first time, the claim that only the Pro Max receives it |
The contradiction isn't resolved simply because one side is wrong. The earlier reports concerned Apple's plans for the technology itself, not its distribution across models. A supplier can have modules in production without it being certain how many devices they will ultimately be used in.
The precedent of 2023
The Pro models have been split once before. With the iPhone 15 Pro, the tetraprism telephoto lens remained exclusive to the Max model; the smaller Pro had to do without the 5x optical zoom. Since then, the two devices have only differed in size, weight, and battery life.
The fact that Apple has more internal space in the iPhone 18 Pro Max fits the picture: The device is expected to be thicker and heavier than its predecessor. A lens mechanism requires space, and that space is more limited in the smaller casing.
What the breakdown changes for the purchase decision
Should this be confirmed, your choice between the two Pro models will shift from a matter of taste to one of compromise. Those who prefer the more compact device will no longer just be foregoing a larger display and longer battery life, but also the only genuine camera innovation of this generation – and will be paying the premium for access to it compared to the largest model.
For the DACH market, the Pro models are already at the upper end of the price range, and further price increases are expected in September due to rising material costs. A feature tied to the most expensive model therefore has a greater impact than in markets with lower price levels.
Our assessment: The statement aligns with the supplier documents and the 2023 precedent, but is based on a single, unverified source. Until Apple unveils the models, it remains an indication, not a definitive finding.
Four weeks until the resolution
Clarity will only come at the keynote. Both Pro models are expected in September, along with the first foldable iPhone; the preview of the September event summarizes what else is in store. Invitations are expected in the last week of August.
Would the variable aperture be reason enough for you to opt for the Pro Max, even though the device is thicker and heavier – or will you stick with the more compact Pro and forgo the extra features? Let us know in the comments where you draw the line.
