Buy DJI Mini 2 or Air 2.

Considering simplicity and portability, Mini2 is definitely the first choice. The body of Mini2 smaller than 249g can avoid the trouble of real-name registration in official website, Civil Aviation Administration, and save a lot of worry when traveling. From the point of view of taking pictures, Air2 is definitely better than Mini2, but Mini2 has also reached the level of12 million pixels, which is not professional photography. It is enough to take photos and record videos at ordinary times.

Although the performance of mini2 has improved on the basis of mini, the obstacle avoidance has not changed. Mini2 only avoids obstacles at the bottom, which means it is useful when landing (in fact, it is useless to avoid obstacles when landing), and air is to avoid obstacles in three directions.
