Unfortunately neither the Panasonic Lumix DMC-FX75 (Lumix DMC-FX70) nor Nikon Coolpix P7100 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 P7100's 3.00" LCD screen is slightly larger than Panasonic FX75's 2.7" screen.
In addition to the size advantage, Nikon P7100 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, Panasonic FX75 has a fixed type screen which provides less flexibility in shooting positions compared to P7100.
