Abstract: A camera system lens or image sensor is moved to change the distance between the image sensor the lens in order for the image sensor to capture an-focus of an object. The camera system includes one or more calibration values indicating distances between the lens and the image sensor for different distances to objects, such as a macro calibration value and an infinity calibration value. These one or more calibration values are used by the camera system when manually focusing the camera system (e.g., a user manually sets the camera system to a macro setting or an infinity setting) or when automatically focusing the camera system on an object. These one or more calibration values are dynamically updated during use of the camera system, allowing the camera system to adapt to various factors such as changes in environment, pressure applied to the camera system, and so forth.
