A camera bag is important, because it keeps your equipment safe and organized.

For very small cameras, there are ones that just hold the camera and no other accessories, except possibly the wrist strap.

Then there are large bags that not only hold a camera substantial in size, but also additional lenses and a flash.

Though there are ones that come everywhere in between.

You shouldn’t let a camera dangle from your neck (or wrist, if you use a wrist strap). A neck or wrist strap should be seen as analogous to a seatbelt rather than as a tool for convenience.

I use a tote bag designed for camera gear by Peak Design, a San Fransisco-based company. It holds three of my cameras (one of which is very small) and an external flash.
