Apple has announced the iPhone 18 Pro and iPhone 18 Pro Max with a 48MP Fusion Main camera that adds a physically variable aperture. The two Pro models also introduce manual controls for aperture, shutter speed and white balance, plus a histogram for assessing exposure in the Camera app.
The announcement, dated September 9, 2026, describes the feature as the first time aperture control has been available on an iPhone. Apple also says the camera uses a new sensor and computational-imaging pipeline, although the release does not provide independent test results or comparative image data.

What changed in the camera
The iPhone 18 Pro models add a variable physical aperture to the 48MP Fusion Main camera, allowing the opening through which light reaches the sensor to change.
Apple says the mechanism uses six laser-cut blades and a new rotor mechanism to move between aperture settings. The Camera app provides four manually selectable aperture settings. The announcement does not list all four, but identifies operating points including ƒ/1.48, ƒ/1.8 and ƒ/4.
Apple says the camera can also adjust the aperture automatically. It can widen the opening to ƒ/1.48 in low light to admit more light, or narrow it to ƒ/4 when more depth of field is wanted. Depth of field is the range of distances that appears acceptably sharp in an image.
That physical adjustment is different from a software blur effect applied after capture. A wider aperture generally allows more light to reach the sensor and can produce a shallower depth of field. A narrower aperture generally admits less light but can keep more of a scene sharp. The practical result depends on factors including focal length, subject distance, lighting and the camera mode.
Apple positions the system as both an automatic feature for everyday photography and a manual tool for users who want more control. The company attributes sharper and more detailed Main-camera images to the new sensor and computational-imaging pipeline, but those descriptions remain manufacturer claims rather than independent measurements.
The camera system also adds texture and grain controls to Photographic Styles. Apple says cinematic effects can be applied after capture to video recorded at up to 60 frames per second, while Time-lapse mode supports 4K and Dolby Vision HDR.
How the aperture and manual controls work
The new Pro Controls experience expands the Camera app beyond automatic exposure. Users can manually adjust:
- aperture;
- shutter speed; and
- white balance.
Shutter speed determines how long the sensor records light and can affect motion blur. White balance changes how colours are rendered under different light sources so that neutral objects appear neutral.
The Camera app also includes a histogram. This is a graph showing how brightness levels are distributed across an image. It can help a photographer identify whether highlights or shadows may be clipped, although a histogram does not by itself guarantee technically correct exposure or a successful photograph.
Apple says an API is available to developers for additional control across the aperture range in their own applications. That could allow third-party camera apps to build different interfaces or workflows around the hardware. The announcement does not establish how widely those APIs will be adopted, or whether every camera mode, lens and application will support the full range.
Manual controls do not replace computational photography. Apple separately describes a new computational-imaging pipeline and upgraded Photographic Styles, so images will still be shaped by processing as well as by the settings selected before capture.
Availability and pricing
Pre-orders for the iPhone 18 Pro and iPhone 18 Pro Max begin September 12, 2026, and availability begins September 18 in the initial markets. Apple lists India among more than 65 countries and regions included in the first pre-order wave.
Both models will be offered with 256GB, 512GB, 1TB and 2TB of storage. Apple lists U.S. starting prices of $1,199 for the iPhone 18 Pro and $1,299 for the iPhone 18 Pro Max. The announcement supplied for this article does not include an India-specific rupee price.
