Size and weight are big decision factors when you are trying to find the ideal camera for your needs.
In this section, we are going to illustrate the Nikon S4100 and Pentax X-5 side-by-side from the front, back and top in their relative dimensions. Nikon S4100 has external dimensions of 95 x 57 x 20 mm (3.74 x 2.24 x 0.79″) and weighs (including batteries). Pentax X-5 has external dimensions of 119 x 86 x 107 mm (4.69 x 3.39 x 4.21″) and weighs 595 g (1.31 lb / 20.99 oz) (including batteries).
Below you can see the front-view size comparison of the Nikon S4100 and the Pentax X-5. Nikon S4100 is clearly the smaller of the two cameras. Its body is 24mm narrower, 29mm shorter and 87mm thinner than Pentax X-5.
Now lets look at the top view comparison of Nikon S4100 and Pentax X-5.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon S4100 is 595g lighter than the Pentax X-5 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Nikon Coolpix S4100 nor Pentax X-5 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 S4100 and Pentax X-5's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Pentax X-5 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 Nikon S4100 has a fixed type screen which provides less flexibility in shooting positions compared to X-5.
