I want to buy a used SLR camera for 3000 yuan. Only my mobile phone doesn't go out to use at ordinary times, and I like taking pictures and renting houses. Is it suitable for buying?

If you like taking pictures and want better photo quality, then buying a camera is a good choice. Cameras can provide higher quality photos and more shooting options, and are more suitable for shooting scenes that need higher quality photos than mobile phone cameras, such as shooting room layout and tourist attractions when renting a house.

Secondly, for the second-hand SLR camera with a budget of 3,000 yuan, you need to ensure that the quality and performance of the camera meet your requirements and avoid buying a problem camera. I suggest that you carefully check whether the functions of the camera are normal before buying, and try to choose a reputable seller to buy.

Finally, if you only need to take pictures occasionally, you may not need to buy a camera. Cameras need more time and energy to learn and use, and need to be carried and maintained, which is more troublesome than taking pictures with mobile phones. Therefore, if you only need to take pictures occasionally, and the photo quality is not very high, then the mobile phone camera is enough to meet your needs.
