    Leica: Witness to a Century

    The Leica is both a product of the twentieth century's inventive spirit and the means by which that spirit could be documented for posterity. As the first handheld camera, the Leica made possible a new kind of documentary photography, and included among its devoted fans are many of the century's greatest photographers. Its combined qualities of precision and compactness made it an essential tool for photographers everywhere, and today more than ever the Leica is prized by collectors.
