Size and weight is a big decision factor when you are trying to find the ideal camera for your needs.
In this section, We are going to illustrate Olympus SZ-30MR and Samsung NX20 side-by-side from the front, back and top in their relative dimensions. Olympus SZ-30MR has external dimensions of 106 x 69 x 40 mm (4.17 x 2.72 x 1.57″) and weighs 226 g (0.50 lb / 7.97 oz) (including batteries). Samsung NX20 has external dimensions of 122 x 90 x 40 mm (4.8 x 3.54 x 1.57″) and weighs 341 g (0.75 lb / 12.03 oz) (including batteries).
Below you can see the front view size comparison of Olympus SZ-30MR and Samsung NX20. As you can tell, actually this is not a fair size comparison since Olympus SZ-30MR has a built-in lens but Samsung NX20 doesn't. Once you put a lens on NX20, its thickness will increase significantly.

Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Olympus SZ-30MR is significantly lighter (115g ) than the Samsung NX20 which may become a big advantage especially on long walking trips.
Again, this comparison may not be very useful in real life as we are comparing the weight of a camera with a built-in lens to the body-only weight of an interchangeable lens camera. Once you put a lens on NX20, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither Olympus SZ-30MR nor Samsung NX20 provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Olympus SZ-30MR and Samsung NX20's LCD screens has the same diagonal size of 3".
On the other hand, Samsung NX20 sports a
Fully Articulated screen which you can change the angle and position of the screen almost freely, making it possible to shoot from waist or over the head levels, and especially very useful for shooting selfies and video. Olympus SZ-30MR's LCD screen is a fixed type which provides almost no flexibility in shooting positions compared to NX20.
