What should I choose for entry-level photographic equipment?

If you don't buy second-hand, buy a micro-sheet or card machine. You can focus on a relatively high-end card machine, which is basically a one-time investment. If you buy a micro-order, you will usually continue to buy lenses later. SLR has declined, there is no need to buy it now, but if it is used, SLR can be given priority. As for the mobile phone, it is still a mobile phone after all. The real entry is to use a camera. Only the camera can provide enough mobility. You can learn to take pictures with your mobile phone after the fever has gone down.
