Apple appears to be taking a measured step toward expanding the photographic capabilities of its flagship devices, with early production activity now underway for a variable aperture camera system expected to arrive with the iPhone 18 Pro lineup later this year.
According to a report from Korea’s ETNews, key suppliers have begun preparing components tied to the new camera design. The shift marks a notable departure from Apple’s long-standing reliance on fixed-aperture lenses, which have remained unchanged in principle from the iPhone 14 Pro through to the iPhone 17 Pro generation.
In those devices, the main camera operates at a constant ƒ/1.78 aperture. That design keeps the lens fully open during shooting, regardless of lighting conditions. A variable aperture system, by contrast, allows the lens to physically adjust, widening in low light to capture more detail and narrowing in brighter environments to manage exposure more precisely. The approach also offers more flexibility in controlling depth of field, an area where smartphone cameras have traditionally depended heavily on software simulation.
Industry sources cited in the report say Chinese optical manufacturer Sunny Optical has already started producing actuator components, which are essential for enabling the mechanical movement of the aperture. Assembly of full camera modules is expected to follow in the early summer months.
Apple’s primary camera partner, LG Innotek, is reportedly preparing its own production lines, with equipment installation underway at its facility in Gumi, South Korea. The company is expected to take on a larger share of the workload this time, reflecting the added complexity of the system. Other module makers, including Cowell, are also expected to participate in the supply chain.
This would not be the first time Apple has leaned more heavily on a single supplier when introducing a more intricate camera design. A similar pattern was seen with the tetraprism zoom lens used in the iPhone 15 Pro Max, where LG Innotek initially handled production before broader participation followed.
The possibility of a variable aperture camera in Apple’s future devices has been circulating for some time. In late 2024, supply chain analyst Ming-Chi Kuo indicated that both Pro models in the iPhone 18 series would adopt the feature. Subsequent reports suggested that Apple had continued discussions with suppliers into 2025, signaling that development was progressing rather than exploratory.
The iPhone 18 Pro and Pro Max are expected to be introduced around September, alongside what is described as Apple’s first foldable iPhone. For now, the camera system remains one of the more closely watched elements of that launch, as Apple tests how far it can extend hardware-based photography controls in a space increasingly shaped by computational imaging.
There has been no public confirmation from Apple, and the company typically does not comment on supply chain developments. Still, the reported production activity suggests that at least part of the work has moved beyond planning and into execution.

For users, the change would represent a rare shift in how iPhone cameras physically operate, not just how they process images afterward. Whether that translates into a noticeable difference in everyday use will only become clear once the devices are in hand.
