In the next generation of iPhones, the Pro Max version may present advantages over the Pro model, not only in terms of dimensions but also in advanced photographic features. The main speculated advantage lies in increased zoom range and the introduction of a lens aperture variation, a feature that would be unprecedented in Apple's devices.
If this information is confirmed, this would be the second time in iPhone history that the Pro Max would be technically superior to the Pro. The first occurrence was observed in the iPhone 15 Pro Max, which featured the tetraprism lens, absent in the smaller version. Implementing a variable aperture would allow for more sophisticated image captures even in low-light conditions, regardless of using Night Mode.
The ability to vary the lens aperture is a significant attraction for consumers seeking the top-of-the-line model for maximum quality in photos and videos. Currently, Apple phones operate with fixed focus, making only small adjustments digitally. The new mechanism would be physical, incorporating a small shutter in one of the cameras.
Portrait Mode, for example, would simulate this depth modification, which is determined by changing the aperture. Instead of the constant f/1.7 used in the iPhone 17 Pro and Pro Max, the new model would allow adaptation to different standards, controlling light entry and offering adjustable depth perception. According to MacRumors, it is not yet defined whether this adjustment will be manual or automatic, but it would represent a differentiator to position the iPhone as equipment similar to a DSLR.
Although aperture adjustment is not an exclusive innovation of smartphones, other companies have already used it. Samsung implemented this feature in older models, such as the Galaxy S9 and Galaxy S10, with the Galaxy S10 being the last from the company to have a variable aperture. Furthermore, recent rumors suggest that the South Korean giant is developing the return of this functionality in the Galaxy S27 Ultra, expected in early 2027, aiming to compete directly with the iPhone 18 Pro Max.
Chinese brands already offer flagship phones on the market with variable lens apertures. Among them are Honor, with the Magic6 Pro, and Huawei, which offers the feature in its Pura and Mate lines, exemplified by the Huawei Pura 70 Ultra and Huawei Mate 60 Pro+. In these examples, the adjustment is mechanical, varying between f/1.4 and f/2.0 in the case of the Honor device, and can reach f/4.0 in the most advanced Huawei models.
A leak in June already signaled the existence of the variable aperture, based on internal documents from Tata Electronics, a lens supplier for Apple devices. It is expected that the model will use Sony IMX905 sensors, which support aperture adjustment. Additionally, the website 9to5Mac points out that the iPhone 18 Pro Max will come equipped with 6x optical zoom and better performance in dark environments.
This novelty suggests that the larger size of the line would be explored by Apple to enhance its camera system. Rumors also indicate that the model would be larger and heavier than the iPhone 17 Pro Max. Regarding the launch, it is predicted to arrive in September, along with the iPhone Ultra, Apple's first foldable device.
