I want to ask you what's the difference between SLR full-matching machine and full-matching machine? What do you mean, half-right? Thank you.

In fact, there is no difference. All for taking pictures. The low-pass filter photosensitive device of the whole machine is larger and the half width is smaller. Quan Huafu's machine is just a business strategy. For example, hundreds of thousands of Hermes bags are bags, and tens of dollars of cheap goods are bags.
