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 NX10 and Olympus E-PL9 side-by-side from the front, back and top in their relative dimensions. 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). Olympus E-PL9 has external dimensions of 117 x 68 x 39 mm (4.61 x 2.68 x 1.54″) and weighs 380 g (0.84 lb / 13.40 oz) (including batteries).
Below you can see the front-view size comparison of the Samsung NX10 and the Olympus E-PL9. Olympus E-PL9 is clearly the smaller of the two cameras. Its body is 6mm narrower, 19mm shorter and 1mm thinner than Samsung NX10.
Here is the back view size comparison of the Samsung NX10 and Olympus E-PL9.
Now lets look at the top view comparison of Samsung NX10 and Olympus E-PL9.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Olympus E-PL9 is significantly lighter (119g ) 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 Olympus E-PL9 has a smaller Four Thirds sensor, Olympus E-PL9'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 Samsung NX10 nor Olympus PEN E-PL9 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Samsung NX10 and Olympus E-PL9's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Olympus E-PL9 features a
Tilting screen where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels whereas the Samsung NX10 has a fixed type screen which provides less flexibility in shooting positions compared to E-PL9.
