SLR cameras should put the lens up or down in the camera bag. What is the reason for putting the lens down clearly in the instruction manual?

1. Because the SLR is a lens-replaceable model, the camera bag should be placed in a T shape with the lens facing down.

2. Before placing the camera bag, you should check and adjust the buffer position in the bag. You should jam the sides of the fuselage so that the lens will not directly press the bottom of the camera bag. If the height of the camera bag is difficult to be high enough, you can add a sponge pad at the bottom of the camera bag.

3. Main principle: Most rear camera bags may collide in the horizontal direction, so that the relatively fragile bayonet part will not be damaged.
