When you half-press the shutter button, which two functions are performed by the camera?

Explanation:
Half-pressing the shutter activates two things at once: autofocus, which finds and locks the subject in focus, and exposure metering, which measures the scene’s brightness to help set the correct exposure. Zooming the lens isn’t part of this action; changing focal length is controlled separately. So the two functions performed are focusing the camera and measuring the light.
