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 1 J4 and Nikon 1 S2 side-by-side from the front, back and top in their relative dimensions. Nikon 1 J4 has external dimensions of 100 x 60 x 29 mm (3.92 x 2.36 x 1.12″) and weighs 232 g (0.51 lb / 8.18 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 the Nikon 1 J4 and the Nikon 1 S2.
Here is the back view size comparison of the Nikon 1 J4 and Nikon 1 S2.
Now lets look at the top view comparison of Nikon 1 J4 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 significantly lighter (42g ) than the Nikon 1 J4 which may become a big advantage especially on long walking trips.
Also keep in mind that body weight is not the only deciding factor when comparing two interchangeable camera bodies, you also have to take into account the lenses that you will be using with these bodies. Since both Nikon 1 J4 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.
Weather Sealing
Unfortunately neither the Nikon 1 J4 nor Nikon 1 S2 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 Mirrorless Cameras with Weather Sealing
LCD Screen Size and Features
Nikon 1 J4 and Nikon 1 S2's LCD screens have the same diagonal size of 3.00 inches.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
