A leaker emphasizes that the Chinese launch of the Xiaomi 17 Ultra will happen in just a few hours time. Chinese customers can already put down a deposit to become an early adopter of the ultimate Leica camera flagship, while leakers and even Xiaomi boss Lu Weibing share further details about the new Leica camera.

Chinese smartphone fans who want to get their hands on what is likely one of the most exciting flagship phones of next year can already place a deposit of 100 yuan (about $14) to reserve the Xiaomi 17 Ultra ahead of time, as promoted by the Xiaomi Store on Weibo. In one of many posts on this topic, it even explicitly refers to the unreleased handset by stating "Xiaomi 17U is coming?!!", even though it’s still a "blind booking" at this point.

Xiaomi boss confirms Lofic sensor

According to a leaker, official preorders are expected to start between December 15 and December 25, likely as early as next week, as Smart Pikachu claims on Weibo. Moreover, Xiaomi CEO Lu Weibing has also commented on an interesting camera detail, although the Xiaomi 17 Ultra is not mentioned explicitly in this case.

In a response to a Weibo post, Weibing emphasizes that the "Lateral Overflow Integration Capacitor" technology will become a trend for smartphone cameras, as it is designed to deliver high dynamic range in a single exposure while also preventing noise and LED flicker. The Xiaomi president’s statement can be seen as confirmation that the new 1-inch Omnivision OV50X sensor in the Xiaomi 17 Ultra utilizes Lofic.

Leica camera optimized for 35mm shots?

Meanwhile, a Chinese leaker has also commented on the Xiaomi 17 Ultra in recent days. In his Weibo posts, he emphasizes that Xiaomi has optimized the new 1-inch camera for the usual portrait focal length, which presumably refers to 35mm. Unlike the optical 35mm camera of the Vivo X200 Ultra, this involves cropping, but since the sensor is larger, the 35mm on the Xiaomi 17 Ultra could still look comparatively good.

Either way, the leaker also mentions optimized filters, bokeh algorithms, and live photos. In another post, he points to significantly improved pictures with strong backlighting, which is likely an advantage of the Lofic sensor. He also notes that zoom videos on the Xiaomi 17 Ultra are extremely smooth. Last but not least, another Xiaomi 17 Ultra post claims that Xiaomi has improved stabilization and focus tracking to camera-level performance.
