Weather Sealing

LCD Screen Size and Features
Nikon A1000 and Pentax WG-3 GPS's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Nikon A1000 features a
Tilting screen where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels whereas the Pentax WG-3 GPS has a fixed type screen which provides less flexibility in shooting positions compared to A1000.
