In this section, We are going to illustrate Nikon A900 and Olympus SH-3 side-by-side from the front, back and top in their relative dimensions.

Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Olympus SH-3 is 18g lighter than the Nikon A900 but we don't think this will make a significant difference.
Unfortunately neither Nikon Coolpix A900 nor Olympus Stylus SH-3 provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors.

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 Olympus SH-3 has a fixed type screen which provides less flexibility in shooting positions compared to A900.
