Notes & Features: Optical image stabilization, 3.0-inch touchscreen LCD, Dynamic Range Optimization Very closely related to RS1000. Only differences are clip-on (screwless) face plates rather than screw-on kind, slightly more internal memory, newer software CD, and slight differences to scene and Auto Picture modes.
