Professional machine Nikon's machine is rich in color compared with Canon's, and Canon's color is soft. Nikon's machine has a longer service life than Canon's, but Nikon's camera is not as good as Canon's camera in home machines. Strictly speaking, it is a high-end entry-level machine, but the quality is comparable to that of a mid-range machine. It has a good reputation and a large market share. It is Nikon's flagship product. Advantages are: continuous shooting is fast, 4.5 sheets per second; Manual exposure compensation is large; A leveling pentaprism with a magnification of 0.94; Focus and photometric linkage, 1 1 point focus; Many special function keys, easy to control; Standard battery life is long, with high-definition camera function.
