Weather Sealing
Unfortunately neither the Nikon Coolpix P80 nor Nikon Coolpix P100 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Nikon P100's 3.00" LCD screen is slightly larger than Nikon P80's 2.7 screen.
In addition to the size advantage, Nikon P100 LCD screen also has a
Tilting feature where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels. On the other hand, Nikon P80 has a fixed type screen which provides less flexibility in shooting positions compared to P100.
