Amateur photographers, is it necessary to upgrade Quan Huafu?

Many photographers will face a problem after they start taking pictures for a while. Does the full-frame camera need to be upgraded? Or people who are going to buy cameras are also struggling with half-frame and Quan Huafu's machines.

There are many comments and arguments about upgrading or not. I won't go into details. What I think is that each has its own value and market, and everyone's needs are different.

If the budget is enough and the quality is high, go to Quan Huafu. If the budget is not plentiful, the requirements for image quality are not too high, or if you just shoot children, travel and other scenes, half a picture is enough.
