The 12.1-megapixel DMC-TZ8 features a 25mm wide-angle 12x optical zoom f/3.3-4.9 LEICA DC VARIO-ELMAR lens (35mm camera equivalent: 25-300mm) in a compact body. The 25mm wide-angle lens has about twice the shooting area of the standard 35mm lens. The powerful 12x zoom can also be used in motion picture recording. In 3-megapixel resolution mode, the Extra Optical Zoom function provides additional magnification, extending the zoom power to 23.4x by using the center part of the CCD.

The Intelligent Resolution (I.R) Technology gives a high resolution look to digital zoom images as well as ordinary images. The image is divided into contour areas, texture areas and smooth areas. And optimum image processing is applied to each type of area. This enables 16x Intelligent Zoom that achieves about 1.3 times the usual zoom magnification with almost no loss of image quality. The Intelligent Resolution Technology also achieves sharp images in modes that use fewer pixels to enable high sensitivity and high speed.
