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 Panasonic LS5 and Nikon S3100 side-by-side from the front, back and top in their relative dimensions. Panasonic LS5 has external dimensions of 97 x 62 x 27 mm (3.82 x 2.44 x 1.06″) and weighs 126 g (0.28 lb / 4.44 oz) (including batteries).

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon S3100 is 8g lighter than the Panasonic LS5 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Panasonic Lumix DMC-LS5 nor Nikon Coolpix S3100 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors. If weather sealing is a must-have feature for you, check these sections: Top Compact Cameras with Weather Sealing
LCD Screen Size and Features
Panasonic LS5 and Nikon S3100's LCD screens have the same diagonal size of 2.70 inches.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
