It is always good to know what to look for when you are searching for a gadget. When it comes to digital cameras it is important to know that it is not a matter of having the most amount of mega pixels. As long as there are at least five, it should be fine. This is of course unless you are using the camera for professional photography purposes. Then more mega pixels would be recommended along with a god optical lens. There are other features that cameras have such as face recognition and smile technology.
