Nikon has announced its latest DSLR, the D5500. A lightweight, compact DX-format camera with a 24.2MP sensor, it?s the first of its type to offer a vari-angle touchscreen. The D5500 replaces the D5300 in Nikon?s range, and while it offers much the same features the company says it?s a much slimmer and lighter prospect. There?s a deep grip for easier handling and built-in Wi-Fi that lets you transfer and share shots via your phone or tablet.
