The arrival of the Nikon D7100 comes two-and-a-half years after the announcement of its predecessor the D7000, and it’s a pretty serious upgrade. Significantly, Nikon Europe’s presentation of the camera describes the D7100 as the company’s ‘flagship DX model’, and omitted mention of the D300S in the company’s DSLR lineup. Certainly, the gap between the Nikon D7100 and D600 now leaves little obvious room for a ‘D400.’
Compared to its predecessor the D7000, the Nikon D7100
doesn’t just offer an upgraded sensor with a higher pixel-count. It also features a significantly upgraded AF system, with 51 AF points (15 cross type) as opposed to 39 in the older model. It shares these specifications, and the Multi-Cam 3500DX designation with the D300S, but Nikon promises the autofocus algorithms from the D4 which could, in part, explain the extended sensitivity range (with the D7100 able to focus in light as low as -2EV, according to its specifications).
