it depends on your needs. Introduction and advanced photography (you can shoot a film with good composition with your mobile phone, but you are not satisfied with the imaging effect of your mobile phone), portable (a small bag can be taken out of the door), the quality of the film is not to participate in more professional competitions or press releases, and the operation is fast (for entry-level SLR cameras such as Nikon D53). M6 has a high cost performance. I bought an M6 camera set with 18-15 lenses (there are Nikon D85 Quan Huafu professional high-end SLR and D75 entry-level Quan Huafu SLR at home), which has a macro function of 3cm (of course, the macro effect can't be compared with that of D53 plus Sigma 17-7 wide-angle macro head, but it's ok to take part in general community photography competitions if you use it well), and the 15mm medium focus end can zoom in on objects hundreds of meters away. It is also good to shoot the moving object after focus, and it is reasonable to be called "one machine goes to the world" in the micro-single. The most important settings, such as the reversible touch control screen, shooting mode /iso value/aperture or shutter, can be set by three turntables on the right shoulder, and full-screen focusing (you can focus where you want to shoot with your finger touching the screen, which is unmatched by entry-level and mid-range SLR) is very friendly to novices. Just going out to play, if you stand alone, the battery is not enough, so you need to buy a spare one.
