Camera System and Photography: Hasselblad Partnership in Practice
Overview: What the Hasselblad Partnership Brings
OnePlus’ collaboration with Hasselblad was touted as a transformative moment for its photography chops. The branding promises refined color science, more predictable skin tones, and a more expansive dynamic range. In practice, the camera system blends a Sony-sourced main sensor with a high-resolution ultra-wide, aiming to deliver versatile results across daylight, indoor, and challenging lighting conditions. The marketing emphasis is on “calibrated natural color,” with the goal of producing images that look accurate to real life while preserving vivid detail. We approached camera testing with an open mind, noting both the improvements and the remaining gaps compared to best-in-class devices in the same year.
Main Camera: Sony IMX689 with Hasselblad Potency
The main sensor remains the Sony IMX689, a 48 MP wide-angle module that one could recognize from the OnePlus 8 Pro era. The Hasselblad branding adds a “signature” layer on top—primarily in color calibration and post-processing presets within the camera app. The result is a more confident color rendering in everyday scenes, with more consistent white balance and a smoother tonal transition in midtones. In well-lit conditions, the resulting images tend to be clean, with sharp details and minimal noise, especially when subjects sit within the central portion of the frame. The 1/1.43″ sensor size helps preserve detail in bright scenes, and the pixel-binning approach yields attractive results for standard 12 MP outputs that most users share across social platforms.
Ultra-Wide and Distortion Reduction: The Real Highlight
Where the OnePlus 9 shines is the 50 MP ultra-wide camera, a significant upgrade in sensor size and optics compared to its predecessor. The large 50 MP sensor helps capture more light, improving performance in dimmer environments and enabling higher-quality video capture. A standout improvement is the new ultra-wide lens design that dramatically reduces distortion—a common challenge for ultrawide modules. In practical terms, you’ll notice less curvature at the edges when shooting landscapes or architecture, making it easier to produce usable, undistorted wide-angle shots without post-processing gymnastics. In low light, the ultra-wide gains credibility, delivering cleaner shadows and more subtle gradations than older ultrawide systems.
Depth Sensor and Portrait Capabilities
A dedicated depth sensor supplements depth perception for bokeh and portrait shots. While modern computational photography often relies on AI-driven segmentation, the depth sensor helps refine edge detection and depth maps, resulting in more natural subject isolation in portrait modes, especially when you’re dealing with complex backgrounds or variable lighting. The overall portrait experience is solid, with pleasing skin tones and credible background blur control, although it may still miss the “studio-like” precision offered by some premium systems in this class.
Front Camera and Video Capabilities
The 16 MP front camera balances selfies with reasonable detail and skin-tone accuracy, making it suitable for social posts and video calls. For video, the OnePlus 9 supports 8K at 30fps, 4K at 30/60fps, and Full HD at up to 240fps, coupled with gyro-EIS stabilization to minimize shake during handheld shooting. While 8K footage is more about future-proofing than everyday practicality, the collection of modes offers flexibility for creators who want to explore high-resolution or high-frame-rate footage without switching devices. The combination of robust video options and strong color profiling helps the OnePlus 9 stand out for users who value camera versatility as part of their daily toolset.
Real-World Camera Performance: What to Expect
In typical daylight scenes, the OnePlus 9 tends to deliver clear, detailed images with balanced exposure. Color rendering can lean slightly warmer in some samples, a consequence of the Hasselblad tuning that aims for natural tones rather than punchy saturation. In challenging lighting—low light, high-contrast scenes, or backlit subjects—the camera system remains capable, but you’ll still notice the limitations common to mid-flagship devices: a bit more noise in shadows, limited dynamic range compared to top-tier competitors, and occasional slight processing artifacts in aggressive HDR scenes. The Hasselblad partnership clearly elevates the overall tone management and color calibration, but it isn’t a magic wand; shot discipline and lighting still matter for the best results. For casual photography, the OnePlus 9 offers dependable performance with a distinct, consistent look that many users may prefer to the cooler or more clinical color profiles seen on some rivals.
