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 Samsung NX mini and Nikon D750 side-by-side from the front, back and top in their relative dimensions. Samsung NX mini has external dimensions of 110 x 62 x 23 mm (4.33 x 2.44 x 0.91″) and weighs 196 g (0.43 lb / 6.91 oz) (including batteries). Nikon D750 has external dimensions of 141 x 113 x 78 mm (5.55 x 4.45 x 3.07″) and weighs 840 g (1.85 lb / 29.63 oz) (including batteries).
Below you can see the front-view size comparison of the Samsung NX mini and the Nikon D750. Samsung NX mini is clearly the smaller of the two cameras. Its body is 31mm narrower, 51mm shorter and 55mm thinner than Nikon D750.
Here is the back view size comparison of the Samsung NX mini and Nikon D750.
Now lets look at the top view comparison of Samsung NX mini and Nikon D750.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Samsung NX mini is significantly lighter (644g ) than the Nikon D750 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 Nikon D750 has a Full frame sensor and Samsung NX mini has a smaller 1' sensor, Samsung NX mini's lenses for a similar focal length and aperture will generally be lighter and smaller than the Nikon D750 lenses.
Weather Sealing
Thanks to the weather-sealed body of the D750, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the NX mini.
