Would you like to ask about the function of Canon lens package?

Canon's own lens bag as a temporary package can reduce scratches caused by mutual friction between lenses during storage or travel, and has no waterproof effect. When traveling, the lens bag is still very practical because of the collision of equipment that may be carried. Generally, when traveling, as a professional camera bag, it usually has a rainproof cover, or it can be packed in a practical self-sealing plastic bag and put in a lens bag to facilitate travel. Because I often go out to shoot, I can always put a good quality self-sealing plastic bag in my camera bag, but if possible, I can carry a large "lock lock" fresh-keeping box in my camera bag as a waterproof tool. I hope it helps you.
