Because the model of 7d is too old and the noise reduction algorithm has some problems, its picture quality is the weakest among the seven or eight ancestral cmos machines. (The high-quality picture quality is even weaker than that of the contemporary 550d).
The core of a camera is image quality. Even if it has an all-metal body and continuous shooting speed of 8 frames per second, it is useless if the picture quality is poor.
70d inherits the excellent focusing system of 7d (focusing and photometry systems are identical), and has a brand-new 2000w pixel cmos, which is obviously improved in image quality and high sensitivity compared with 7d. It also adds a flip screen that is very convenient for daily use. With the extremely fast real-life focusing (there is no one in the fastest SLR at present), the flip screen is extremely practical and very easy to use. This is beyond 7 days. Moreover, the continuous shooting at 7 frames per second is fast enough, and the fuselage is lighter and easier to use.
Personally, unless you are a professional journalist and often go in and out of some extreme environments, 70d is definitely better than 7d under normal use. It can be said that apart from the all-metal body and several shortcut keys, 7d has no advantages. What's more, the 70d is also equipped with Canon's latest dual-pixel af technology, and the practicality of real-time framing has reached the extreme of SLR, which can be regarded as a SLR with certain revolutionary significance. With the brand-new 18- 135stm, it can be said to be a breakthrough product in terms of image quality and practicality.
