Abstract: An electronic device is provided. The electronic device includes a first camera module including a first lens set, a second camera module including a second lens set, and a processor connected to the first camera module and a second camera module. The processor is configured to move the first lens focus on a subject, resulting in an auto focus (AF) value and an image obtained by the first camera module, evaluate reliability of the AF value, based on the reliability of the AF value, calculate a movement parameter of the second lens set, corresponding to a movement parameter of the first lens set, and move the second lens set depending on the calculated movement parameter.
