A spokesperson for Xiaomi stated that recently, numerous social media accounts have posted videos that take out of context and distort the content of a teardown video by a certain tech blogger regarding the Xiaomi 17 Ultra Leica Edition, claiming that “the zoom ring is fake and controlled by software.” This claim is seriously at odds with the facts. In response to these malicious distortions and misleading claims, the original teardown blogger has already issued a clarification. Regarding the structural principles of the zoom ring, we offer the following clarification to debunk these rumors: The mechanical structure of the zoom ring on the Xiaomi 17 Ultra Leica Edition is complex and precise. Rotating the external zoom ring drives the internal gear train. A small gear within the gearset drives the movement of the gear shaft. An optical displacement sensor on the side of the telephoto module detects the shaft’s displacement, accurately identifying the angle of rotation of the zoom ring and converting it into an electrical signal. This enables an innovative interaction where physical rotation controls the phone’s zoom. Additionally, the zoom ring supports customizable settings, such as adjusting EV and applying filters, allowing users to select their most frequently used adjustment parameters.
