Earlier today, the company shared a short video on Weibo, revealing a new concept version of the phone, which is aptly known as the Xiaomi 12S Ultra Concept. What sets this model apart from the original is its rear camera array, where a secondary 1-inch 50 MP sensor now occupies the middle portion of the island instead of a 48 MP periscope. But that’s not all that’s different.

— Richard Lai (@richardlai) November 2, 2022 Due to the lack of a lens, this sensor is actually fully exposed, though it is still well protected. This is thanks to a layer of sapphire glass, which also provides protection to the phone’s primary 1-inch 50 MP camera and the repositioned 48 MP periscope. Meanwhile, surrounding the exterior of the concept model’s circular camera island is a mount where you can attach an adapter that supports Leica M series lenses. That’s right. The reason why the secondary sensor is fully exposed is because it is designed to work with interchangeable lenses – transforming the Xiaomi 12S Ultra Concept from a smartphone to an actual mirrorless camera. Additionally, the company adds that this version of the phone comes with the ability to shoot in 10-bit RAW, as well as access to new external lens-supported camera app features such as focus peaking, zebra lines, and histogram. As shown from the video, a protection ring is placed on the camera island’s mount when it is not in use. In a way, it’s convenient that Xiaomi retains the phone’s original Leica-enhanced primary and telephoto cameras so users can still shoot photos without having to attach a lens. However, there’s no denying that featuring two 1-inch 50 MP sensors on a single device is kind of an overkill. But hey, the company did it anyway.

Even if it did, it wouldn’t be surprising if the phone ends up as a China-only exclusive like its sibling, let alone fetch an even heftier price tag. (Source: Engadget / Xiaomi Global [Twitter])
