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 Olympus SH-1 and Nikon S100 side-by-side from the front, back and top in their relative dimensions. Olympus SH-1 has external dimensions of 109 x 63 x 42 mm (4.29 x 2.48 x 1.65″) and weighs 271 g (0.60 lb / 9.56 oz) (including batteries). Nikon S100 has external dimensions of 99 x 65 x 18 mm (3.9 x 2.56 x 0.71″) and weighs 175 g (0.39 lb / 6.17 oz) (including batteries).
Below you can see the front-view size comparison of the Olympus SH-1 and the Nikon S100. Nikon S100 is 10mm narrower and 24mm thinner than Olympus SH-1 but it is also 2mm taller.
Here is the back view size comparison of the Olympus SH-1 and Nikon S100.
Now lets look at the top view comparison of Olympus SH-1 and Nikon S100.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon S100 is significantly lighter (96g ) than the Olympus SH-1 which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Olympus Stylus SH-1 nor Nikon Coolpix S100 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 S100's 3.50" LCD screen is slightly larger than Olympus SH-1's 3 screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
