If you don't buy second-hand, 5000 yuan is only enough to buy aps-c frame body (SLR or non-reverse) with macro lens. Of course, both of them have to be entry-level models for home use, and the professional budget is not enough. But fortunately, you don't need any camera performance to shoot food, so even if you buy the most basic body, the macro lens is generally not very cheap, and it will cost more than half of the budget. For example, Longteng 90 is over 2000 yuan (this is still the old version), and there are less than 3000 yuan left. By the way, you can only buy old entry models like D5300, or slightly newer models like D3500 and D3400. I wonder if you have any extra budget to buy lamps, table legs, scenery and so on. If not, you have to allocate some budget for these, and these accessories are also very important. In short, with a budget of 5000 yuan, it will be very nervous not to buy second-hand goods. If you don't need shooting details, you can consider buying a lens with a certain close-up ability instead of buying a special macro lens, so the budget of the lens can be reduced a lot.
