A system to be used in a digital still camera to control zooming of the zoom lens, uses programmed data written in a micro controller unit (MCU) instead of the known cams that are usually used to mechanically control zooming of the zoom lens of digital still cameras, and the system is used to control auto-focusing of the zoom lens with the very mechanism used for zoom controlling by receiving electronic signals (pulses) from the MCU or electronically controlled distance measuring system of the digital still camera.
