Analyst Ming-Chi Kuo has revealed that the upcoming iPhone 18 Pro models will feature a significant camera upgrade with the introduction of variable aperture technology.

This innovative technology, enabled by advanced equipment from BE Semiconductor (BESI), will allow users to control light entry, thereby enhancing image quality.

Unlike previous iPhone models that utilized a fixed aperture, this new feature will enable users to adjust the amount of light entering the lens, similar to capabilities seen in some Android devices since 2018.

While Android devices like the Xiaomi 14 Ultra have already implemented variable aperture systems, Apple's approach could set new industry standards by offering more granular control akin to professional cameras.

Current Android implementations typically provide only two preset positions for aperture adjustment, whereas Apple's design is expected to offer a wider range of control.

The addition of variable aperture technology could significantly enhance Apple's existing photography tools, such as Smart HDR and Night mode, leading to improved overall image quality.

Historically, iPhones have relied on computational methods to achieve effects like bokeh due to their fixed aperture, but the new system will allow for more natural depth of field adjustments.

However, the effectiveness of the variable aperture system may be limited by the size of the camera sensor, necessitating larger sensors to fully utilize mechanical aperture control.

This anticipated feature represents a major advancement in mobile photography, providing users with greater control over depth of field and lighting adaptability.

Integrating this technology into the iPhone 18 Pro will pose engineering challenges, but collaborations with suppliers like Sunny Optical and Largan Precision are expected to address these issues.

Looking ahead, Apple is also expected to release the M5 Ultra chip by 2026, which will utilize advanced SoIC packaging to enhance performance and efficiency.

The competitive landscape among smartphone manufacturers underscores the push for advanced camera features, as companies strive to enhance user experience.
