How to adjust the lens of Sony MC 1500C camera?

Originally, as a professional camera, many functions can be manually controlled, which is one of the professional performances of professional cameras. However, the prototype of this machine is a small DV for home use, and the prototype is operated by touch screen. You know, the requirement of home machines is fool-like operation, full automation, almost no manual setting by users, and you can take pictures after turning on the machine. MC 1500 is such a huge home computer, so if you want to focus manually, you can only enter the menu through the touch screen and find the focusing option. After activation, you can focus by adjusting the unique adjusting ring on the lens. If you want to zoom manually, go back to the menu and tell me that the function of the adjusting ring is changed to zoom. Professional cameras generally have at least two or three adjusting rings, and their functions are fixed.
