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 S1000pj and Sony S2100 side-by-side from the front, back and top in their relative dimensions. Nikon S1000pj has external dimensions of 96 x 62 x 23 mm (3.78 x 2.44 x 0.91″) and weighs 175 g (0.39 lb / 6.17 oz) (including batteries). Sony S2100 has external dimensions of 98 x 61 x 27 mm (3.86 x 2.4 x 1.06″) and weighs 167 g (0.37 lb / 5.89 oz) (including batteries).
Below you can see the front-view size comparison of the Nikon S1000pj and the Sony S2100. Nikon S1000pj is 2mm narrower and 4mm thinner than Sony S2100 but it is also 1mm taller.
Here is the back view size comparison of the Nikon S1000pj and Sony S2100.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony S2100 is 8g lighter than the Nikon S1000pj but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Nikon Coolpix S1000pj nor Sony Cyber-shot DSC-S2100 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
Sony S2100's 3.00" LCD screen is slightly larger than Nikon S1000pj's 2.7" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
