Nikon CoolPix A100 features a 20.1 megapixel CCD sensor, and a wide-angle 5x optical zoom lens, that is equivalent to 26mm to 130mm in 35mm terms. The camera is powered by a rechargeable lithium-ion battery, and features a 2.7inch screen on the back. It's also compact weighing just 119g with the battery and memory card, and 19.8mm thin, with a metal front plate. There are a number of scene modes making it easy to use the camera, but for those that want a little bit more control you can also set the ISO and white balance settings yourself, including custom white balance. Exposure compensation can be set from -2 to +2. There are 8 creative effects, scene auto selector that automatically detects the scene, 16 manually selectable scene modes, a smart portrait mode (with skin softening, foundation makeup, soft, and vividness settings), and auto (program) mode where you can set the white balance, continuous shooting (on or off), ISO speed, and auto focus (AF) settings. Video options allow you choose the resolution (maximum 720p, 25fps), set the autofocus mode to single or continuous, and switch wind noise reduction on and off. In the setup menus you have the option to apply a date stamp, switch electronic VR on or off, plus set the time and date.
