"The D5500 is the world's smallest, lightest, and slimmest digital SLR camera, and the first Nikon digital SLR camera to be equipped with a touch screen vari-angle LCD monitor that supports intuitive touch operation as well as a built-in Wi-FiŽ function.
The D5500 offers superior image quality and rich reproduction capabilities for excellent detail with an effective pixel count of 24.2-million pixels, a Nikon DX-format CMOS sensor, and the EXPEED 4 image-processing engine."
