Apple is revealed to be developing mechanical hardware to adjust camera aperture, which is expected to be used in the iPhone 17 series at the earliest

On July 24th, technology media The Information published a blog post today, revealing that Apple is developing a mechanical aperture solution, which is expected to be deployed on the iPhone 17 series at the earliest. It is reported that Apple is developing mechanical hardware internally to allow users to manually adjust the iPhone’s aperture size. Users can manually adjust the aperture and control the depth of field effect, allowing the subject to remain in focus while the background becomes blurred. Note: Apple has already introduced this effect in the portrait mode of the iPhone, but the effects are adjusted and optimized by AI algorithms, and manual mechanical hardware means it will bring more playability to iPhone users.

Portrait mode sometimes struggles to separate subjects in the foreground and background, and mechanical hardware can solve this problem.

Aperture refers to the opening through which light enters the camera lens. The current camera lenses of the iPhone all use fixed apertures, but variable apertures have been commercially available in Android phones for a long time. Typical products are Samsung's Galaxy S9 series.

Sources indicate that this mechanical aperture solution is currently in the development stage and may be equipped on the iPhone 17 series as early as September 2025, and may be limited to iPhone 17 Slim/Ultra products.
