The load capacity of the AK2000/4000 is achieved through the extremely large torque motors with infinite power and a new high-performance chip combined with the intelligent anti-shake algorithm. The anti-shake feature is also suitable for use in extreme environments and can support the weight of professional DSLR cameras and lenses of all brands. The low-power LCD touch panel allows for easy adjustments of focus, zoom, sensitivity, ISO, white balance, exposure compensation, motor speed, scene settings, and automatic rotation mode settings. The touch panel supports operational updates for long-lasting functionality. The simple design style and popular beveled angle design do not obstruct the screen during recording and facilitate easy framing. The high-precision magnetic induction knob can control not only the focus and zoom but also the highly precise rotation of the motor, providing you with a smooth experience. The M4 kernel MCU, the 0.02° high-precision magnetic encoding sensor, and the W5 generation control algorithm with a correction speed of 2000 times per second offer a load-adaptive algorithm. At the same time, the Feiyu ON APP can connect to the camera via WiFi to adjust parameters over Bluetooth. The combination of WiFi with compatible devices can control recording, focusing, zoom, sensitivity settings, white balance, exposure value, and switch mode functions.
