Weight is another important factor especially when deciding on a camera that you want to carry with you all day.

Unfortunately neither Nikon Coolpix P300 nor Fujifilm FinePix T400 provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors.
