Also known as disposable cameras, these cameras are made with film inside. Once the film has been exposed, the whole camera is sent to the lab and the film is developed, the camera is useless and can be disposed.

These cameras are very cheap in the short term.
The quality of the design, build and materials is improving.
They can be taken places you wouldn't dare take an expensive camera (e.g. on a canoe, on the beach, or even underwater!)
Usually small and light, makes easy to travel with.
Rather easily available.

The photo quality is often not as good as the other types of cameras.
Can be more expensive in the long term.
Not as flexible with fixed lenses, focus and apetures.
Can be bulky if more than a couple of films are needed.

The disposable cameras are great for usage in certain occasions and cases (e.g. underwater (for amateur photographers), in a short holiday where you forgot to bring your camera, when there is little space for camera equipment.)
