Size and weight is a big decision factor when you are trying to find the ideal camera for your needs.
In this section, We are going to illustrate Nikon 1 S1 and Nikon 1 S2 side-by-side from the front, back and top in their relative dimensions. Nikon 1 S1 has external dimensions of 102 x 61 x 30 mm (4.02 x 2.4 x 1.18″) and weighs 197 g (0.43 lb / 6.95 oz) (including batteries). Nikon 1 S2 has external dimensions of 101 x 61 x 29 mm (3.98 x 2.4 x 1.14″) and weighs 190 g (including batteries).
Below you can see the front view size comparison of Nikon 1 S1 and Nikon 1 S2. Nikon 1 S1 has the same height with Nikon 1 S2. On the other hand, with a width of 102mm, it is 1 wider and also with a thickness of 30mm, it is 1mm thicker than Nikon 1 S2.
Here is the back view size comparison of Nikon 1 S1 and Nikon 1 S2.
Now lets look at the top view comparison of Nikon 1 S1 and Nikon 1 S2.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Nikon 1 S2 is 7g lighter than the Nikon 1 S1 but we don't think this will make a significant difference.
Also keep in mind that body weight is not the only deciding factor when comparing two interchangeable camera bodies, you have to also take into account the lenses that you will be using with these bodies. Since both Nikon 1 S1 and Nikon 1 S2 have the same Nikon 1 lens mount and 1 inch Sensor sized sensors, lenses will not be a differentiator on total size of the system.
Unfortunately neither Nikon 1 S1 nor Nikon 1 S2 provides any type of weather sealing in their body, 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 Mirrorless Cameras with Weather Sealing
