In a camera, the lens is fixed - focusing is done by moving the lens forward or backward to get a sharp image. In the human eye, muscles surrounding the eyeball 'distort' the lens to change its focal length.
When using the one-shot focusing mode on a camera, the focus is locked once the shutter button is pressed halfway. This mode is best for still subjects. On the other hand, the AI Servo focusing mode continuously adjusts focus as the subject moves, making it ideal for capturing moving subjects.
The touch screen Canon camera features a high-resolution display that allows for easy navigation and control of settings. It also has touch autofocus capabilities for quick and precise focusing. Additionally, the camera offers various shooting modes and settings that can be accessed and adjusted directly on the touch screen.

AI Servo and AI Focus are two different focusing modes in photography. AI Servo is used for moving subjects, continuously adjusting focus to keep the subject sharp. AI Focus automatically switches between single and continuous focus modes based on the subject's movement.

The main difference between USM (Ultrasonic Motor) and STM (Stepping Motor) focusing mechanisms in camera lenses is the way they operate. USM uses ultrasonic vibrations for fast and quiet focusing, while STM uses a stepping motor for smooth and silent focusing.
