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 Olympus E-PL6 and Sony NEX-6 side-by-side from the front, back and top in their relative dimensions. Olympus E-PL6 has external dimensions of 111 x 64 x 38 mm (4.37 x 2.52 x 1.5″) and weighs 325 g (0.72 lb / 11.46 oz) (including batteries). Sony NEX-6 has external dimensions of 120 x 67 x 43 mm (4.72 x 2.64 x 1.69″) and weighs 345 g (0.76 lb / 12.17 oz) (including batteries).
Below you can see the front-view size comparison of the Olympus E-PL6 and the Sony NEX-6. Olympus E-PL6 is clearly the smaller of the two cameras. Its body is 9mm narrower, 3mm shorter and 5mm thinner than Sony NEX-6.
Here is the back view size comparison of the Olympus E-PL6 and Sony NEX-6.
Now lets look at the top view comparison of Olympus E-PL6 and Sony NEX-6.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Olympus E-PL6 is 20g lighter than the Sony NEX-6 but we don't think this will make a significant difference.
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 Sony NEX-6 has an APS-C sized sensor and Olympus E-PL6 has a smaller Four Thirds sensor, Olympus E-PL6's lenses for a similar focal length and aperture will generally be lighter and smaller than the Sony NEX-6 lenses.
Weather Sealing
Unfortunately neither the Olympus PEN E-PL6 nor Sony Alpha NEX-6 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
Olympus E-PL6 and Sony NEX-6's LCD screens have the same diagonal size of 3.00 inches.
Both cameras feature
Tilting screens where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels.
