OnePlus 12 5G Camera System
The camera system remains a focal point for OnePlus, continuing its partnership with legendary camera manufacturer Hasselblad for color calibration and image processing. The triple-camera setup includes:
- A 50MP Sony IMX908 main camera with a large 1/1.28″ sensor, optical image stabilization, and an f/1.4 aperture
- A 48MP ultrawide camera with a 150-degree field of view and autofocus capability
- A 64MP periscope telephoto camera with 3x optical zoom, 30x digital zoom, and OIS
The Hasselblad collaboration is evident in the natural color science and portrait mode capabilities, while OnePlus has developed its own computational photography features, including “HyperShot HDR” that captures and combines multiple frames for improved dynamic range.
Low-light performance has seen significant improvements thanks to larger individual pixels and enhanced image processing. The “Nightscape Pro” mode captures detailed night scenes with minimal noise, while the new “Astro Mode” allows for impressive astrophotography when the phone is mounted on a tripod.
Video capabilities include 8K recording at 24fps, 4K at 60fps with HDR10+ support, and action-steady video stabilization. The “Movie Mode” provides manual controls for serious videographers, including focus peaking, zebra patterns, and LOG format recording for professional color grading.
The front-facing camera uses a 32MP sensor with autofocus capability, supporting 4K video recording and offering improved low-light performance compared to previous generations.
