Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Nikon P520 is 5g lighter than the Nikon P510 but we don't think this will make a significant difference.
Unfortunately neither Nikon Coolpix P510 nor Nikon Coolpix P520 provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors.
