The digital camera market has extremely expanded in the last ten years. The zoom lens for digital camera is especially
the key determining factor of the camera body size and image quality. Its technologies have been based on several analog
technological progresses including the method of aspherical lens manufacturing and the mechanism of image
stabilization. Panasonic is one of the pioneers of both technologies. I will introduce the previous trend in optics of zoom
lens as well as original optical technologies of Panasonic digital camera "LUMIX", and in addition optics in 3D camera
system. Besides, I would like to suppose the future trend in digital cameras.
