A slight update to the D5300, the Nikon D5500 is a midrange DX-format that sports a 24MP CMOS sensor with no optical low-pass filter (OLPF) and the company's latest Expeed 4 processor. This combination offers an ISO range of 100-25600 and 5 fps burst shooting, while the 39-point AF system can track subjects in '3D'. Other features include a fully articulating 3.2" touchscreen LCD with 1.04M dots and 1080/60p video. We've been using it for a few days - take a look at our gallery of samples.
