Weather Sealing
Unfortunately neither the Nikon Coolpix S1000pj nor Panasonic Lumix DMC-ZS45 (Lumix DMC-TZ57) 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
Panasonic ZS45's 3.00" LCD screen is slightly larger than Nikon S1000pj's 2.7" screen.
In addition to the size advantage, Panasonic ZS45 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 S1000pj has a fixed type screen which provides less flexibility in shooting positions compared to ZS45.
