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 Pentax K-50 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). Pentax K-50 has external dimensions of 130 x 97 x 71 mm (5.12 x 3.82 x 2.8″) and weighs 650 g (1.43 lb / 22.93 oz) (including batteries).
Below you can see the front-view size comparison of the Olympus E-PL6 and the Pentax K-50. Olympus E-PL6 is clearly the smaller of the two cameras. Its body is 19mm narrower, 33mm shorter and 33mm thinner than Pentax K-50.
Here is the back view size comparison of the Olympus E-PL6 and Pentax K-50.
Now lets look at the top view comparison of Olympus E-PL6 and Pentax K-50.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Olympus E-PL6 is significantly lighter (325g ) than the Pentax K-50 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 Pentax K-50 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 Pentax K-50 lenses.
Weather Sealing
Thanks to the weather-sealed body of the K-50, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the E-PL6.
LCD Screen Size and Features
Olympus E-PL6 and Pentax K-50's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Olympus E-PL6 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 Pentax K-50 has a fixed type screen which provides less flexibility in shooting positions compared to E-PL6.
