It's so quiet that you can record sound while the motor is moving. Setup is fast. You connect the motor to the camera, plug the motor into the controller, the battery and power. After launching the app, you connect with the controller with Bluetooth. The first thing that you need to do is set limits. The first limit will be infinity for the lens. The next limit will be the near end of focus for the lens or for the planned shot. Next you can set up to four independent focus points with the buttons A, B, C, D representing each point. With the focus point set, you can jump from position A, B, C or D with a touch of a button and the app. Your focus shifts to A, to B, to C, to D and then back to A again. You have a lot of control over the speed of the focus shift from fast to extremely slow. The touch RT app allows continuous focusing. Slide your finger over the surface of the tablet or phone and the focus motor follows your movements. This is the focus shift that was just performed using the tablet. One of the accessories of the system is the follow focus puck which is the industry standard that will be familiar to any cinematographers. A really exciting accessory is the follow focus handle for a single operator running gun shoulder rigs. The basic reward includes the motion control module, the tablet and the lens gear motor. Other rewards include the basic stealth RT kit and the 15mm rod system. The final accessories are the handle, the pack, oversized gears, the tray and the gears.
