How to focus when shooting Canon autofocus lens?

When taking pictures with an automatic pan/tilt,

If it is non-ultrasonic motor autofocus, then turn to AF gear, then set the focus point, and press the shutter for half a turn to focus. In LV mode, if the AF-ON button is pressed, the machine will focus automatically.

If you use a non-ultrasonic motor for manual focusing, you need to turn to MF gear, then set the focusing point, press the shutter half and turn the focusing ring, and the green point aiming at the machine viewfinder will always be on. Look at your eyes in LV mode, as long as you feel clearly.

If the ultrasonic motor is used for autofocus, set the AF position, then set the focus point, and press the shutter half to focus.

In the process of focusing, you can manually intervene in the focusing process without damaging the motor.

Is this clearer?
