Many video journalists shoot on medium-sized prosumer cameras, but in recent years there has been another wave of "small cameras". With the flip, iphone and Kodak Zi 8 there are now outlets gathering their footage using these tiny cameras. For other organisations it is simply a lightweight option as a back-up in case a journalist turns up before a camera operator.
More and more accessories are appearing, especially for the iPhone. This video by the International Journalists Network looks at the results you can get from these tiny cameras.
