New information continues to come about the iPhone 18 Pro and iPhone 18 Pro Max models, which Apple is expected to introduce next month. While the two phones are expected to come with a faster A20 Pro processor, higher capacity batteries and improved camera systems, one of the innovations on the camera side may be specific only to the iPhone 18 Pro Max. It is stated that the variable aperture main camera, which was previously claimed to be available in both Pro models, will only be used in the larger model, according to the latest claim. Thus, Apple can increase the difference in camera hardware between the iPhone 18 Pro and Pro Max again. The company had previously used some camera components that required physical space only in the largest iPhone model.
Claims that a variable aperture main camera will be used in the iPhone 18 Pro series have been on the agenda for a while. The latest information shared by Ice Universe shows that Apple may limit this hardware to the iPhone 18 Pro Max. According to the source, the main reason for this is that the variable aperture mechanism requires more space inside the phone. While the larger body of the iPhone 18 Pro Max can provide the necessary space for the placement of this component, it may be difficult to implement the same layout on the smaller iPhone 18 Pro. However, the claim does not share technical details such as sensor size, the values between which the aperture will change or how many different stages the mechanism will have.
What can variable aperture provide on the iPhone 18 Pro Max camera?
The variable aperture system allows the camera to physically change the lens aperture according to shooting conditions. While the lens aperture does not change in fixed aperture cameras, which are widely used in smartphones, the amount of light reaching the sensor can be controlled at the hardware level thanks to the variable aperture. While a wider aperture helps the sensor collect more light in low-light environments, a narrower aperture can be advantageous, especially in strong daylight or in shots where a larger area is desired to be kept clear. In addition, changing the aperture value also has a physical effect on the depth of field. However, the difference this system will make in practice will be more clearly understood when evaluated together with the sensor, lens structure and image processing software that Apple will use.
Some claims have been shared before that Apple could physically enlarge the iPhone 18 Pro Max. Ice Universe claimed that the phone would weigh 240 grams and be 9 mm thick. If these values are correct, the iPhone 18 Pro Max will have a slightly thicker and heavier body compared to the current iPhone 17 Pro Max. It is not yet known whether this change in the body is related only to the camera system; Larger battery and different internal component layouts can also have an impact on thickness. However, the latest claim that the variable aperture mechanism requires additional space suggests that the Pro Max’s larger case may give Apple more leeway when it comes to camera hardware.
It has been seen before that Apple distinguishes between the two Pro models in terms of camera hardware. The company included a tetraprism-designed telephoto camera in the iPhone 15 Pro Max, which it introduced in 2023, and offered 5 times optical zoom in this model. The smaller iPhone 15 Pro, released in the same year, was offered for sale with a different telephoto camera that provided 3 times optical zoom. The physical space required by the tetraprism system was a factor in the hardware in question being initially limited to the larger Pro Max model. Therefore, applying a similar approach to the variable aperture mechanism in the iPhone 18 family does not completely contradict Apple’s past product preferences.
On the other hand, the information that the variable aperture will only be available on the iPhone 18 Pro Max has not been confirmed yet. It is not possible to finalize camera features before Apple announces new iPhone models, and there is a possibility that the company may make changes in its final product plans. If the claim turns out to be true, the choice between iPhone 18 Pro Max and iPhone 18 Pro will not only depend on screen and battery size; The main camera system will also become one of the elements that distinguish the two models from each other. The actual contribution of the variable aperture to photo quality will depend on the technical features of the mechanism and how Apple will combine it with the computational photography system. For this reason, although the hardware in question looks remarkable on paper, it will be necessary to wait for Apple to announce the camera details to evaluate the advantage it will provide for the user.
