The camera also offers a 2.5-inch LCD screen, 3/4-inch thin form factor, technology to help ensure a balanced exposure and sharpness, a D-Lighting function to automatically compensate for insufficient flash or excessive back lighting, and more. The Coolpix S1 will be available this April for a suggested retail price of US$379.95.
