Overview
- Apple shipped a physical variable aperture in the iPhone 18 Pro main camera using six hair‑thin, laser‑cut blades that move between four discrete aperture settings.
- The Camera app now exposes built‑in Pro controls that let users set aperture, shutter speed, white balance and view a live histogram for more manual tuning.
- A new Reference capture mode cryptographically signs raw sensor data in Apple's Private Cloud Compute and stores an unalterable reference image alongside the edited photo.
- Apple’s production iris differs from a 2025 patent that described a soft‑membrane aperture, showing the company explored multiple engineering approaches before choosing a conventional blade design.
- Reporters note practical trade‑offs: past phones with variable apertures were dropped from some lines because of size, cost and fragility, and many users can still get shallow depth of field on older iPhones using Portrait, Macro, telephoto lenses, or close framing.
