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 Sony S950 and Nikon S8100 side-by-side from the front, back and top in their relative dimensions. Sony S950 has external dimensions of 93 x 56 x 24 mm (3.66 x 2.2 x 0.94″) and weighs 167 g (0.37 lb / 5.89 oz) (including batteries). Nikon S8100 has external dimensions of 104 x 60 x 30 mm (4.09 x 2.36 x 1.18″) and weighs 180 g (0.40 lb / 6.35 oz) (including batteries).
Below you can see the front-view size comparison of the Sony S950 and the Nikon S8100. Sony S950 is clearly the smaller of the two cameras. Its body is 11mm narrower, 4mm shorter and 6mm thinner than Nikon S8100.
Here is the back view size comparison of the Sony S950 and Nikon S8100.
Now lets look at the top view comparison of Sony S950 and Nikon S8100.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony S950 is 13g lighter than the Nikon S8100 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Sony Cyber-shot DSC-S950 nor Nikon Coolpix S8100 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 S8100's 3.00" LCD screen is slightly larger than Sony S950's 2.7 screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
