Why is the camera in the camera bag?

There is an isolation pad in the pocket under the lens. In order to place the isolation pad, it is necessary to clamp the camera so that it does not move back and forth in the bag, but also to bear part of the weight of the fuselage so that the lens does not directly contact the bottom of the bag. Try not to put it on your back or side.

It is usually recommended to lay flat, that is, the base contacts the surface and the lens is horizontal. When you go out, the lens is at the bottom and the fuselage is at the top. There is a simple reason. If the lens is facing up, dust will deposit on the CCD. On the contrary, it will only be relatively easy to clean at the end of the lens. It is usually deposited directly on the bottom of the cassette without any influence.

Canon's SLR camera bag can generally hold lenses. Pull the camera bag apart first, and just lay it flat without disassembly, so that the interface between the lens and the camera will not be greatly worn. After putting it away, zip it up again.

There is no most reasonable statement, only what suits you. No matter how good the camera bag is, you must be careful not to put it on a high place. You'd rather leave it dirty on the ground, and remember that there is no absolutely safe bag. Whether the camera is safe or not depends on your work habits.

The way to put the camera in the SLR camera bag is this: a small SLR bag is just put into a SLR with a lens, which is suitable for going into battle lightly. As shown in the figure: the triangular medium-sized bag can hold a SLR and two lenses, and a tripod can be fixed under it.
