Supply chain manufacturers have begun producing components for the iPhone 18 Pro’s variable aperture camera system, according to a new report. It marks a significant milestone ahead of the device’s expected September launch — and a first in iPhone history.
All previous iPhone cameras feature fixed apertures. A variable aperture allows more control of light reaching the sensor for sharper, properly exposed images.
First iPhone variable-aperture camera enters production
Apple’s component supply chain for the variable aperture camera destined for the iPhone 18 Pro and Pro Max for likely fall 2026 release has swung into action, according to ETNews. Chinese optics firm Sunny Optical began manufacturing the actuator. That’s the mechanical component that physically moves the aperture blades in the new system.
The production timeline should unfold in stages. LG Innotek, which will assemble the finished camera modules, is scheduled to begin its own manufacturing in June or July of this year. It’s already installing dedicated equipment at its Gumi facility in South Korea to prepare for mass production. Alongside Sunny Optical, Chinese manufacturer Luxshare ICT will also supply actuator mechanisms for the system.
Camera modules of this kind typically enter full production two to three months before a product ships. And actuator components that feed into them begin manufacturing at least a month earlier. That puts the timeline squarely on track for Apple’s likely September 2026 release.
What variable aperture means for your photos
Found on dedicated cameras like DSLRs, a variable aperture works by controlling how much light reaches the camera sensor. It narrows it in bright daylight to prevent overexposure. And it opens wide in dim conditions to let in as much light as possible. The result is sharper, better-exposed images regardless of where you’re shooting.
Most smartphone cameras, including the current iPhone lineup, use a fixed aperture. iPhone 17 is locked at f/1.6. Dedicated cameras, by contrast, typically offer variable apertures ranging from f/2.8 to f/22. That lets photographers control exposure and achieve different aesthetic effects.
On the iPhone 18 Pro, the variable aperture should integrate into the main 48-megapixel Fusion camera. That lets users control the amount of light passing through the lens to the sensor. Beyond exposure control, it also opens up new creative possibilities around depth of field, or how much of a scene appears sharp versus blurred. iPhone shooters have never had that direct hardware access before.
A complex new technology, and why LG Innotek matters

Bringing variable aperture to a smartphone is considerably more challenging than implementing it on a traditional camera. The industry is watching LG Innotek’s role closely. Because this is a new and technically demanding technology, industry observers expect LG Innotek’s share of the main camera module supply to increase significantly.
There’s precedent for this. When Apple introduced its first periscope telephoto camera in the iPhone 15 Pro Max back in 2023, LG Innotek was the sole supplier of that module as well.
The variable aperture system will allow users to physically adjust the lens aperture, giving the camera greater flexibility in controlling light and depth of field. That should enable sharper photos in varied conditions without relying solely on software processing.
iPhone 18 Pro: What to expect besides first iPhone variable-aperture camera
The new variable aperture camera makes headlines, but it won’t be the only upgrade arriving this fall. iPhone 18 Pro might also feature a next-generation A20 chip built on TSMC’s second-generation 2nm process, more power-efficient LTPO+ displays, a smaller Dynamic Island and a simplified Camera Control button.
Apple is expected to launch the iPhone 18 Pro and Pro Max in September 2026 alongside its first-ever foldable iPhone, making for one of the most consequential fall lineups the company has put together in years. While the foldable is likely to attract the most attention, the variable aperture camera gives Pro model buyers a compelling reason to upgrade on its own terms.
