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

Weather Sealing
Unfortunately neither the Nikon Coolpix L840 nor Nikon Coolpix P1000 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.
