As for the Canon 5D2 outdoor shooting lens replacement and packaging issues, please answer them in detail, thank you very much!

1 How to install it? Look at the promotional pictures of photography bags in various online stores. There are various renderings and recommended distribution methods. There are many types. Search and learn by yourself.

2. The body lenses are usually connected, so there is no problem.

3 The body is not delicate, but the lens is. The body of the camera can be used to smash walnuts, but the lens cannot. You can use something like a Big Sanyuan to smash hazelnuts, but you will soon find that all kinds of strange little problems come from nowhere. Strong vibrations may cause light rays. The axis is offset, and the head is basically half disabled. Those who say that it will be fine if the lens is dropped from any height must not pay attention to the image quality. It may not have any functional impact on the surface, but optical instruments are precise!

4 There are 5 manifestations of dust problems: A. The front lens of the lens (or its UV and other filters). This has little impact on shooting. Just clean it with air blowing; B. The rear lens of the lens. group, it may get on it when changing heads, be sure to clean it up, the dust here will have a huge impact on out-of-focus imaging; C low-pass filter (the layer in front of the photosensitive element), there will be black spots on the photo, no need to explain Go ahead and buy a cleaning stick; inside the D lens, dust may slowly enter the lens after long-term use, which is unavoidable in areas with poor air quality. Embarrassing; outside the E lens body and the body, this is completely nonsense~ Just don't turn the faucet down and flush it, hehe. If you don’t know how to clean the lens, ask and add more.

5 If you carry one camera, three heads and one light in a shoulder bag, you will be exhausted unless you hire a camera assistant to help you carry it. If you really want to go hiking and take pictures of the scenery, be sure not to bring so many things with you. Usually, you will end up with two things, but a tripod is a must. Of course, we won’t discuss those who only bring a card machine when climbing Mount Everest. If you don’t understand the specific issue of head selection, ask further. Regarding bags, basically this medium-sized shoulder bag can only be used in the car. If you really want to carry so many bags with you, you should carry them on your shoulders. Kata, Thinktank, and LowerPro all have many good bags. If you choose a suitcase, it will be more complicated. Let’s talk about the specific usage environment.
