What equipment does amateur photography use to mix COS circles?

SLR, in fact, the focal length of lens 24-70 is more practical, which can cope with big scenes and close-ups. 85 fixed focus is too limited, and then there are lights, which are more important than cameras, and all kinds of lighting accessories, soft boxes, soft umbrella color paper and so on, and, uh, reflectors. In fact, even if the framework has the ability to load the whole framework directly, the C-type framework is ok. After all, unless some large or commercial organizations can print and enlarge, most of them are small pictures on the po website, which has little effect on the image quality, and even the worst clothes will still have texture.
