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 NX3000 and Sony a5000 side-by-side from the front, back and top in their relative dimensions. Samsung NX3000 has external dimensions of 117 x 66 x 39 mm (4.61 x 2.6 x 1.54″) and weighs 230 g (including batteries). Sony a5000 has external dimensions of 110 x 63 x 36 mm (4.33 x 2.48 x 1.42″) and weighs 269 g (0.59 lb / 9.49 oz) (including batteries).
Below you can see the front-view size comparison of the Samsung NX3000 and the Sony a5000. Sony a5000 is clearly the smaller of the two cameras. Its body is 7mm narrower, 3mm shorter and 3mm thinner than Samsung NX3000.
Here is the back view size comparison of the Samsung NX3000 and Sony a5000.
Now lets look at the top view comparison of Samsung NX3000 and Sony a5000.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Samsung NX3000 is significantly lighter (39g ) than the Sony a5000 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 Samsung NX3000 and Sony a5000 have the same APS-C sized sensor, their lenses for a similar focal length and aperture will be similar in size and weight.
Weather Sealing
Unfortunately neither the Samsung NX3000 nor Sony Alpha a5000 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.
