Apple confirmed at its September 9 “Surprise and Shine” event that both the iPhone 18 Pro and iPhone 18 Pro Max will feature a variable aperture camera, settling earlier speculation that the technology might be exclusive to the larger model.
The system uses six laser-cut blades, each thinner than a human hair, made from a specialized polymer composite that Apple says balances flexibility with durability.
Rather than locking the lens at a fixed opening, the aperture adjusts automatically depending on the scene. In low-light conditions, it opens wider to allow roughly 50 percent more light onto the sensor than a fixed aperture would permit.
What changes for photographers and video shooters
The practical benefits extend beyond low-light photography. Variable aperture opens up depth-of-field control that was previously unavailable on a smartphone camera, letting the lens physically shape how much of a scene stays in focus rather than relying entirely on software to simulate the effect.
On the video side, the feature brings meaningful upgrades to Cinematic mode. Users can now apply Cinematic mode effects to footage after it has already been captured, rather than committing to the look at the time of recording.
The mode also now supports 60 frames per second, enabling a half-speed slow-motion effect.
The camera system underneath
The variable aperture sits within a new 48-megapixel Fusion main camera. “iPhone 18 Pro has a new 48-megapixel Fusion main camera with variable aperture for creative control that wasn’t possible before,” Apple said at the event. “This is the most advanced camera we’ve ever made.”
Pre-event rumors had suggested Apple might limit variable aperture to the Pro Max to differentiate the two Pro models, a pattern the company has used in past years with certain camera features.
Offering it across both Pro devices keeps the lineup consistent for buyers who prefer the smaller form factor but want the full camera experience.
The iPhone 18 Pro and iPhone 18 Pro Max are available for pre-order now alongside other hardware announced at today’s event, with availability expected September 22.
