Optical and Digital Zoom. Panasonic digital cameras offer an 'Optical Zoom' (for example 10x, 5x etc.), a 'Digital Zoom' (for example, 40x etc) and on the most recent models an 'Extra Optical Zoom' function. Optical zoom is achieved by moving lenses within the camera to magnify the image. Image quality is maintained throughout the zoom. Digital zoom extends the range of the optical zoom. It enlarges the centre of the image to fill more of the captured area . The digital stretching of the image causes a deterioration in the picture quality.
