Can I travel with a SLR?

Of course. But traveling with a SLR is not a good idea. Unless you travel for photography, you don't care about the trouble and heaviness of the SLR, and you don't care about the shadow children who accompany you.

It's really a big burden for a person to hike or climb a mountain. The weight of SLR plus lens is in kilograms. On the other hand, unless it is the so-called Tianya mirror, it is a big trouble to change the lens. Sometimes it may be necessary to change the lens, and some scenes and other lenses are replaced by scenes.

For example, on Nanzhao Island, the sun sets in the west, and a golden light is projected from the back of Sha Yi's mother. If we change the lens, the position of the sun will change.
