Introduce camera recommendation

If the budget is not too big, buy a black card. Although this is a card machine, the picture quality is not very bad. The key is portability and convenience.

A7 is an entry-level Quan Huafu micro-single, because the sensor size is very different, so the picture quality is definitely better, but this machine is very old, and it is also the first generation model of A7 series, so it is not recommended, especially now that a73 has come out and the lens is added, it is not so portable. After all, a full-frame machine.
