The DMC-ZS7 features a 25mm ultra wide-angle 12x optical zoom f/3.3-4.9 Leica DC Vario-Elmar lens. Incorporating Panasonic's advanced optical technologies, this lens system is comprised of 10 elements in 8 groups, with 2 ED (Extra Low Dispersion) lenses and 2 aspherical lenses/3 aspherical surfaces while preserving compactness. This lens system enables a remarkable 25 to 300mm range of focal length in this compact body. The powerful zoom of the DMC-ZS7 can be freely controlled even when shooting motion images. Inheriting the fine rendering and outstanding quality of the Leica Elmar lens, this easy-to-carry camera delivers beautiful images any time, any place.Thanks to the newly incorporated intelligent resolution technology, the intelligent zoom is available with the DMC-ZS7 which extends the zoom ratio by approximate 1.3x maintaining the picture quality even combining a digital zoom. This means the 12x optical can virtually extend to 16x equivalent. Furthermore, the extra optical zoom function that extends zoom power to 23.4x by using the center part of the large CCD to bring subjects even closer.
