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 S01 and Panasonic ZS8 side-by-side from the front, back and top in their relative dimensions. Nikon S01 has external dimensions of 77 x 52 x 17 mm (3.03 x 2.05 x 0.67″) and weighs 96 g (0.21 lb / 3.39 oz) (including batteries). Panasonic ZS8 has external dimensions of 105 x 58 x 33 mm (4.13 x 2.28 x 1.3″) and weighs 210 g (0.46 lb / 7.41 oz) (including batteries).
Below you can see the front-view size comparison of the Nikon S01 and the Panasonic ZS8. Nikon S01 is clearly the smaller of the two cameras. Its body is 28mm narrower, 6mm shorter and 16mm thinner than Panasonic ZS8.
Here is the back view size comparison of the Nikon S01 and Panasonic ZS8.
Now lets look at the top view comparison of Nikon S01 and Panasonic ZS8.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon S01 is significantly lighter (114g ) than the Panasonic ZS8 which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Nikon Coolpix S01 nor Panasonic Lumix DMC-ZS8 (Lumix DMC-TZ18) 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
Panasonic ZS8's 3.00" LCD screen is slightly larger than Nikon S01's 2.5" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
