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 Samsung NX10 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). Samsung NX10 has external dimensions of 123 x 87 x 40 mm (4.84 x 3.43 x 1.57″) and weighs 499 g (1.10 lb / 17.60 oz) (including batteries).
Below you can see the front-view size comparison of the Nikon 1 J4 and the Samsung NX10. Nikon 1 J4 is clearly the smaller of the two cameras. Its body is 23mm narrower, 27mm shorter and 11mm thinner than Samsung NX10.
Here is the back view size comparison of the Nikon 1 J4 and Samsung NX10.
Now lets look at the top view comparison of Nikon 1 J4 and Samsung NX10.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon 1 J4 is significantly lighter (267g ) than the Samsung NX10 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 Samsung NX10 has an APS-C sized sensor and Nikon 1 J4 has a smaller 1' sensor, Nikon 1 J4's lenses for a similar focal length and aperture will generally be lighter and smaller than the Samsung NX10 lenses.
Weather Sealing
Unfortunately neither the Nikon 1 J4 nor Samsung NX10 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 Samsung NX10's LCD screens have the same diagonal size of 3.00 inches.
