Group 1: Clarification of Zoom Ring Mechanism - The zoom ring in the Xiaomi 17 Ultra Leica version features a complex and precise mechanical structure that operates through the rotation of an external zoom ring, which drives an internal gear system [2]. - The gear system includes small gears that move the gear shaft, while an optical displacement sensor detects the movement of the shaft, accurately recognizing the angle of the zoom ring's rotation and converting it into an electrical signal for physical zoom control [2]. - The zoom ring also allows users to customize settings, such as adjusting exposure value (EV) and filters, enabling different users to select their preferred adjustment parameters [2].
