We report the achievement of a highly versatile imager consisting of a tunable fluidic lens with a wide tuning range and three fixed lenses. The device has a volume of less than 1 cm(3) and a short total track length of 12.5 cm. It can function as a regular camera with an ultrawide autofocusing range and as a microscope with 3 microm resolution.
