Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.

LCD Screen Size and Features

On the other hand, Nikon A900 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 Ricoh WG-4 has a fixed type screen which provides less flexibility in shooting positions compared to A900.
