An image capture device (10) is provided which performs a combination of digital and optical zoom techniques to achieve high levels of zoom without sacrificing image quality. In a first embodiment, an opto-digital lens system is provided including a wide angle lens (20) and a normal lens (25), the transition between which is smoothed using moderate digital zooming. Starting from the wide angle fixed optical length, the processor (40) may be used to digitally zoom the captured image. At a predetermined point during the digital zoom operation, the normal lens (25) is placed into the optical path and the processor (40) again digitally zooms the beginning.
