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 Fujifilm X-A2 and Nikon 1 S2 side-by-side from the front, back and top in their relative dimensions. Fujifilm X-A2 has external dimensions of 117 x 67 x 40 mm (4.61 x 2.64 x 1.57″) and weighs 350 g (0.77 lb / 12.35 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 Fujifilm X-A2 and Nikon 1 S2. Nikon 1 S2 is clearly the smaller of the two cameras. Its body is 16mm narrower, 6mm shorter and 11mm thinner than Fujifilm X-A2.
Here is the back view size comparison of Fujifilm X-A2 and Nikon 1 S2.
Now lets look at the top view comparison of Fujifilm X-A2 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 (160g ) than the Fujifilm X-A2 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 have to also take into account the lenses that you will be using with these bodies. Since Fujifilm X-A2 has an APS-C sized sensor and Nikon 1 S2 has a smaller 1-inch sensor, Nikon 1 S2's lenses for a similar focal length and aperture will generally be lighter and smaller than the Fujifilm X-A2 lenses.
Unfortunately neither Fujifilm X-A2 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
LCD Screen Size and Features
Fujifilm X-A2 and Nikon 1 S2's LCD screens has the same diagonal size of 3".
On the other hand, Fujifilm X-A2 features a Tilting screen
