Samsung Planning To Follow iPhone 18 Pro's Variable Aperture Camera

Variable Aperture Camera: Samsung's Strategic Countermove

Samsung is developing a new variable aperture camera system for future flagship smartphones, reigniting a hardware innovation it abandoned years ago. The move positions the Korean tech giant to directly counter Apple's rumored iPhone 18 Pro camera upgrades while shifting mobile photography away from software-dependent fixes toward physical optics. But this isn't Samsung's first attempt—the company previously implemented variable aperture in its Galaxy S9 and S10 series before discontinuing the feature due to thickness constraints and manufacturing costs. Now, with renewed engineering focus and competitive pressure mounting, Samsung believes the technology has matured enough for a sophisticated comeback that could redefine low-light performance and depth control in smartphone imaging.

How Variable Aperture Transforms Mobile Photography

A variable aperture camera dynamically adjusts the opening size that allows light to reach the image sensor—similar to how the human eye's pupil expands in darkness and contracts in bright conditions. In practical terms, this means the lens can widen to an f/1.5 aperture for maximum light capture during night shots, then narrow to f/2.4 or smaller when shooting in daylight to prevent blown-out highlights. Crucially, this physical adjustment provides more authentic exposure control than software-based HDR processing, which often struggles with complex lighting scenarios like sunsets or indoor-outdoor mixed environments.

Beyond exposure management, variable aperture gives photographers direct control over depth of field—the aesthetic separation between a sharp subject and a softly blurred background. While portrait mode effects currently rely on computational segmentation that sometimes misidentifies edges, a true optical aperture adjustment creates natural bokeh with accurate falloff. For content creators and social media photographers, this translates to more professional-looking images straight from the camera without heavy post-processing.

Apple's iPhone 18 Pro Plans Accelerate Industry Shift

Industry analysts widely anticipate Apple introducing its first variable aperture system with the iPhone 18 Pro and Pro Max models this fall. Supply chain discussions between Apple and component manufacturers have progressed through multiple development phases since late 2024, signaling serious commitment to the feature. Notably, every iPhone Pro model since the 14 series has maintained a fixed f/1.78 aperture on its primary camera—a limitation that forces the company to rely heavily on Smart HDR and Night Mode algorithms for exposure balancing.

Apple's potential adoption of variable aperture represents a philosophical pivot toward hybrid imaging: combining computational photography with meaningful optical hardware upgrades. This approach acknowledges growing consumer skepticism about "AI-only" camera improvements, where marketing emphasizes software tricks over tangible sensor or lens advancements. By integrating physical aperture control, Apple could deliver more consistent image quality across lighting conditions while reducing processing latency—a frequent pain point in current computational photography pipelines.

Samsung's Variable Aperture History: Lessons from the S9 Era

Samsung actually pioneered variable aperture in mainstream smartphones back in 2018 with the Galaxy S9's dual-aperture main camera (f/1.5 and f/2.4 modes). The implementation impressed reviewers with its low-light capabilities but faced significant engineering hurdles. The mechanical iris mechanism added noticeable thickness to an era when smartphone slimness was paramount. Manufacturing complexity also drove up component costs at a time when Samsung was aggressively competing on price across its Galaxy lineup.

By the Galaxy S20 series launch in 2020, Samsung quietly retired the feature, betting instead on larger sensors, pixel-binning technology, and advanced AI processing to achieve similar results without mechanical compromises. This decision reflected broader industry trends: manufacturers prioritized thinner designs and multi-camera arrays over single-lens optical innovations. Yet the underlying limitation remained—software corrections couldn't fully replicate the optical precision of true aperture control, especially in challenging mixed-lighting scenarios where algorithms often produced unnatural-looking results.

Why Samsung Is Returning to Variable Aperture Now

Current reports indicate Samsung has requested prototype modules from multiple camera suppliers, signaling serious development momentum. Internal documents reportedly describe variable aperture as "necessary to increase camera competitiveness" in an increasingly saturated premium smartphone market. With computational photography reaching diminishing returns—consumers now expect competent night modes and portrait effects as baseline features—hardware differentiation has become critical for justifying flagship price premiums.

Engineers appear confident they can overcome previous thickness challenges through miniaturized actuator designs and space-efficient module layouts. Advances in materials science have yielded lighter, more durable iris mechanisms that require less physical clearance within the camera bump. Simultaneously, economies of scale from automotive and medical imaging sectors have reduced production costs for precision aperture components. Samsung's strategy hinges on positioning variable aperture not as a gimmick but as foundational hardware that reduces reliance on power-hungry computational processing—potentially extending battery life during intensive photography sessions.

The Hardware-Software Balance in Modern Smartphone Cameras

The renewed focus on optical hardware reflects growing industry recognition that computational photography has limitations. While AI-powered enhancements excel at optimizing well-exposed scenes, they struggle with physically impossible corrections—like recovering detail from completely clipped highlights or eliminating motion blur from long exposures. Physical aperture control addresses these challenges at the capture stage, providing cleaner raw data for subsequent processing.

This hybrid approach also aligns with emerging consumer preferences. Photography enthusiasts increasingly scrutinize "authenticity" in smartphone images, expressing fatigue with over-processed shots featuring unnaturally smooth skin textures or artificial sky replacements. A variable aperture system delivers more optically accurate exposures that require less aggressive software intervention, resulting in images that retain natural texture and dynamic range. For Samsung, this represents an opportunity to appeal to discerning users who value photographic integrity alongside convenience.

Competitive Implications for the Flagship Camera Race

Samsung's potential variable aperture revival sets the stage for a fascinating hardware arms race in 2026–2027 flagship cycles. If both Samsung and Apple deploy the technology within months of each other, consumers will gain unprecedented optical flexibility in premium smartphones. However, implementation details will determine real-world advantages: response speed of the aperture mechanism, precision of automatic adjustments, and integration with existing computational pipelines will all influence user experience.

Critically, this shift may pressure other manufacturers to reconsider optical innovations they've sidelined in favor of software solutions. Brands like Google—which built its Pixel reputation almost exclusively on computational photography—could face difficult choices about hardware investment versus algorithmic refinement. The industry may be entering a new phase where the most impressive camera systems combine intelligent software with meaningful optical advancements rather than relying on one approach exclusively.

What This Means for Everyday Photographers

For most users, variable aperture technology should translate to noticeably better photos without requiring technical expertise. The system would operate automatically—widening in dim restaurants or evening streets, narrowing under harsh midday sun—while delivering more balanced exposures with natural highlight retention. Night photography should see particular improvement, with reduced noise and better color accuracy since the sensor receives optimal light physically rather than relying solely on multi-frame stacking.

Portrait shooters will benefit from more authentic background blur that responds naturally to subject distance and lighting conditions. Unlike current portrait modes that sometimes create "cutout" artifacts around hair or complex edges, optical bokeh produces smooth, graduated falloff that professional photographers recognize as aesthetically pleasing. Even casual social media users should notice their images appearing more polished straight from the camera, reducing dependence on third-party editing apps for basic exposure corrections.

The Next Evolution in Mobile Imaging

Samsung's reported development timeline suggests variable aperture could debut in the Galaxy S27 series or a future Ultra model, positioning it as a direct counterpoint to Apple's iPhone 18 Pro launch. Success will depend on execution—specifically whether engineers achieve the promised reductions in module thickness and cost without compromising reliability. Mechanical components inherently carry higher failure risks than solid-state systems, making durability testing critical before mass production.

Beyond immediate competitive dynamics, this development signals a maturing mobile photography market where innovation cycles extend beyond megapixel counts and AI filters. As smartphones approach optical performance ceilings dictated by physics, manufacturers must get creative with lens mechanics, sensor architectures, and light-path engineering. Variable aperture represents one promising path forward—a return to photographic fundamentals that could make tomorrow's smartphone cameras not just smarter, but optically superior in ways users can actually see and appreciate.

The coming year will reveal whether this hardware renaissance delivers on its promise or becomes another casualty of smartphone design constraints. But one thing is certain: the battle for camera supremacy is shifting back to the lens itself—and that's good news for anyone who believes great photography starts with how light enters the camera, not just how software processes it afterward.
