Apple’s iPhone 18 Pro lineup could finally bring variable aperture technology to iPhones for the first time, according to leaker Digital Chat Station. Both iPhone 18 Pro models will feature variable aperture on the main 48MP Fusion camera plus larger apertures on the telephoto lens, giving photographers DSLR-level control over depth of field and low-light performance when the devices launch in September 2026.

Variable Aperture Brings Manual Control to iPhone Photography
A variable-aperture system physically adjusts the lens opening, letting more light in for low-light shots or narrowing the opening for brighter scenes and deeper depth of field. Current iPhone Pro models use a fixed f/1.78 aperture permanently set to its widest setting, limiting creative control compared to DSLRs where photographers manually adjust aperture for different effects.
For mobile photography enthusiasts, this represents a watershed moment. Variable aperture enables depth of field effects to be performed in-camera instead of being faked through computational photography like current iPhone Portrait mode. You’ll control whether to keep backgrounds sharp or blur them out naturally—no AI guesswork required.
The 48MP periscope telephoto currently sits at f/2.2 on iPhone 17 Pro, with upgrades to around f/2.0 that would let in more light and reduce noise at long focal lengths. Combined with variable aperture on the main camera, the iPhone 18 Pro could match professional camera flexibility in a smartphone form factor.

Split Launch: Pro Models in 2026, Standard iPhone 18 in 2027
The standard iPhone 18 and iPhone 18e will reportedly launch in early 2027, while Apple unveils the iPhone 18 Pro lineup alongside a new iPhone Air and the company’s first foldable iPhone in fall 2026. This staggered release breaks Apple’s traditional single-event launch strategy.
Apple analyst Jeff Pu revealed the iPhone 18 Pro series will feature the A20 chip built on TSMC’s 2nm process with up to 12GB RAM—a significant performance boost. The split schedule could help Apple manage production complexity for variable aperture mechanisms and foldable displays simultaneously.

Variable aperture has been rumored for multiple iPhone generations including iPhone 17, but renowned analyst Ming-Chi Kuo stated in November 2024 it would arrive with iPhone 18 Pro. Digital Chat Station’s track record includes accurately predicting the iPhone 15’s 48MP sensor specifications and iPhone 12 display panel design.
The iPhone 18 Pro camera upgrade positions Apple to compete with Samsung’s Galaxy S26 Ultra, also rumored for variable aperture. If accurate, September 2026 could mark the beginning of DSLR-style smartphone photography becoming mainstream.
FAQs
What does variable aperture mean for iPhone photography?
You can manually adjust lens opening like a DSLR for sharper subject focus or enhanced background blur, controlling depth of field naturally instead of through software.
Will the standard iPhone 18 launch alongside iPhone 18 Pro?
No, iPhone 18 Pro launches fall 2026 while standard iPhone 18 and iPhone 18e arrive in the first half of 2027.
