This week, Digital Chat Station released a detailed leak regarding the Xiaomi 18 Pro Max camera, and a key feature is really catching the attention of anyone who seriously follows the development of mobile photography. The device is being tested using LOFIC HDR 3.0 – the third generation of Lateral Overflow Integration Capacitor sensor technology – combined with a 200MP primary sensor and an equally 200MP periscope telephoto.
This is an engineering prototype, so final specifications may change, but the overall strategy is clear. The Xiaomi 18 Pro Max prototype features a 200MP 1/1.28-inch primary sensor on a 22nm process with LOFIC HDR 3.0 support for extended dynamic range. The use of a dual 200 megapixel camera has been confirmed – the periscopic telephoto module also has a 200 megapixel sensor and supports macro shooting at a distance of 15 cm. LOFIC HDR 3.0 is specially designed to preserve details in highlights and shadows in high-contrast scenes. The Xiaomi 18 Ultra series may move away from the traditional 1-inch sensor approach, opting instead for a LOFIC-based architecture. Xiaomi president Liu Weibing has publicly called LOFIC the future of mobile photography, with standard and Pro models expected in September 2026.
LOFIC – Lateral Overflow Integration Capacitor – is a sensor architecture that handles excess light at the level of individual pixels, preventing it from leaking into neighboring pixels and oversaturation of the frame. Practically speaking, this means preserving details in highlights while capturing information from shadows – something that is usually problematic for traditional sensors in scenes with backlight, sunsets, or mixed lighting. HDR 3.0 is the third iteration of this approach, and each generation has pushed the boundaries of dynamic range. At the previous event, the company’s president clearly emphasized that LOFIC is the future of mobile photography, which shows Xiaomi’s strategic focus on this technology.
Most flagships combine a high-resolution main camera with lower-resolution sensors for the auxiliary lenses, while Xiaomi chooses the same resolution for both cameras, aiming to ensure uniform image quality at all focal lengths. The minimum macro shooting distance of 15 cm on the telephoto makes close-up shots convenient for subject, nature, or gastronomy photography without the need for a separate macro lens.
The most interesting among the leaks is the possible departure of the Xiaomi 18 Ultra series from the 1-inch sensor, which was a key feature of the 17 Ultra. Early engineering samples demonstrate an evaluation of the LOFIC architecture, which provides high dynamic range without the physical size of a 1-inch module. This could be either a technological breakthrough or an economic compromise – we will know for sure after the official release of Ultra. A September launch is expected for the standard and Pro models, with Ultra planned separately later in 2026.
