Recent reports suggest that Apple’s upcoming iPhone 18 Pro models will introduce a variable aperture system in their main cameras, marking a significant advancement in the device’s photographic capabilities. This feature, commonly found in professional DSLR cameras, allows photographers to adjust the lens opening, thereby controlling the amount of light entering the camera and influencing the depth of field.
Traditionally, iPhone cameras have utilized fixed apertures. For instance, the main cameras on the iPhone 14 Pro through iPhone 17 Pro models have maintained a constant aperture of ƒ/1.78. The introduction of a variable aperture in the iPhone 18 Pro would enable users to manually adjust this setting. This adjustment can enhance low-light photography by widening the aperture to allow more light in, or improve image sharpness in well-lit conditions by narrowing the aperture. Additionally, it offers greater control over the depth of field, allowing for more pronounced background blur or sharper focus throughout the image.
The source of this information is the Weibo account Digital Chat Station, which claims to have insights from Apple’s supply chain. According to the leaker, both the iPhone 18 Pro and iPhone 18 Pro Max will feature this variable aperture technology. Furthermore, the main and telephoto lenses are expected to have larger apertures, potentially enhancing performance in low-light scenarios and providing a more pronounced bokeh effect.
This isn’t the first time such a feature has been rumored. In November 2024, analyst Ming-Chi Kuo predicted that the iPhone 18 Pro models would incorporate variable aperture technology. While there were earlier speculations about this feature debuting in the iPhone 17 series, it did not materialize. The consistent emergence of these reports suggests a strong possibility of its inclusion in the upcoming models.
The implementation of a variable aperture system in smartphones presents technical challenges, primarily due to the compact size of the devices. However, advancements in technology and manufacturing processes may have enabled Apple to integrate this feature without compromising the device’s form factor. Collaborations with component manufacturers like Luxshare ICT and Sunny Optical are reportedly underway to develop the necessary actuators for the aperture mechanism.
In addition to the variable aperture, the iPhone 18 Pro lineup is rumored to include other significant upgrades. These may encompass larger image sensors, improved telephoto capabilities, and enhanced computational photography features. Such advancements aim to provide users with a more versatile and professional photography experience, bridging the gap between smartphone cameras and traditional DSLRs.
It’s important to note that while these reports are based on information from supply chain sources and analysts, they remain speculative until officially confirmed by Apple. The company is known for its secrecy regarding product developments, and details can change before the final release.
The iPhone 18 Pro models are anticipated to launch in September 2026. As the release date approaches, more concrete information is expected to emerge, providing a clearer picture of the device’s features and capabilities.
