Apple is prioritizing light control over resolution in the iPhone 18 Pro, featuring a new variable aperture system that boosts low-light performance and depth of field. GN technics/mobile (en-US) reports that this mechanism uses ultra-thin blades to enhance Night Mode photography, while also granting third-party developers full access to these optical controls.

  • According to GN technics/mobile (en-US), the variable aperture mechanism utilizes six blades thinner than a human hair to increase light intake by roughly 50% in low-light scenarios. The report also confirms that Apple is exposing full control of this new optical system to third-party developers via an updated API.
