What's the difference between Canon 7D Mark II and Canon 70D and Canon 7D?

7D2 is an upgraded version of 7D, which went on the market \x0d\7D2 and was discontinued in 7D. \x0d\ is the most advanced machine in Canon's half-frame SLR body. It uses dual processors, so it is heavier, heavier than the half-frame body, and even slightly heavier than the 5D2 in Quan Huafu. Because of the dual processors, the focus is faster and the high-speed continuous shooting is faster. Continuous shooting is faster than Quan Huafu's 5D2 and 5D3, and is suitable for snapshot, such as baby, bird and sports photography. In the state of high-speed continuous shooting, when the shutter is pressed, it sounds like a machine gun, and the speed of continuous shooting is very cool. High-speed continuous shooting is superior to other SLR except 1D series. \x0d\ has a good user interface and many self-settings. Even the operation settings of the upgraded versions 5D2 and 5D3 are the same as those of 7D, not the extended version 5D2. \x0d\7D2 As it has just been listed, the price of the fuselage is more than 10,000, and there is too much water, which will be reduced to about 8,000 in the future. \x0d\70D is Canon's mid-range SLR body, slightly lower than 7D and slightly higher than 700D. \x0d\ The differences of detailed parameters can be compared on the website of SLR equipment.
