A camera strap is an alternative to your normal hands and helps you perform many other activities even when there’s no hand to hold the camera up against. For example, on a hunting campaign out in the deep jungle, you probably wouldn’t let your camera fight the mud and rough surfaces by placing it on the rough terrains. However, if your hands are full of grime and dirt, all you can do is fumble around with the camera in one hand and the other feeding yourself with a banana in another. This is where a camera strap comes into play. It provides you with a place to store the camera while allowing you free hand movement, which is important if you are going to be in the field for an extended period of time.
Camera wrist straps come in a wide variety of colors and materials, and there are some that offer great features such as light-weight materials or built-in hydration systems for keeping the camera from drying out. Many times camera wrist straps come with an additional feature such as Velcro strap fasteners allowing you to easily tighten and loosen the strap. Many professionals who use professional cameras often carry extra batteries, and a wrist strap makes it easy to change out the batteries, and they don’t have to worry about remembering to put them in the right slot, since they are usually built-in to the camera.
Camera sling is similar to a neck sling for carrying accessories, but instead it goes around your neck. The camera is still securely held by the neck strap but instead of the sling across your neck, the straps go around your chest and across your shoulders. Because you are now wearing the camera while holding it, this makes it easier to see the image without having to turn your head to look at the screen. Camera slings are great for hunters and fishermen who have to carry a large camera, like a 16-camera system, which is too heavy to wear on their backs. It is also recommended for pilots who occasionally have to use their plane while holding their camera, and it also makes it easier to get shots from people, since you can just quickly slide your hands along your chest and adjust the strap to find a good angle.
