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 Pentax WG-2 GPS and Samsung NX200 side-by-side from the front, back and top in their relative dimensions. Pentax WG-2 GPS has external dimensions of 122 x 61 x 30 mm (4.8 x 2.4 x 1.18″) and weighs 198 g (0.44 lb / 6.98 oz) (including batteries). Samsung NX200 has external dimensions of 117 x 63 x 36 mm (4.61 x 2.48 x 1.42″) and weighs 223 g (0.49 lb / 7.87 oz) (including batteries).
Below you can see the front-view size comparison of the Pentax WG-2 GPS and the Samsung NX200. Pentax WG-2 GPS is 2mm shorter and 6mm thinner than Samsung NX200 but it is also 5mm wider. As you can tell, actually this is not a fair size comparison since Pentax WG-2 GPS has a built-in lens but Samsung NX200 doesn't. Once you put a lens on NX200, its thickness will increase significantly.
Now lets look at the top view comparison of Pentax WG-2 GPS and Samsung NX200.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Pentax WG-2 GPS is 25g lighter than the Samsung NX200 but we don't think this will make a significant difference.
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 NX200, the total kit will weigh much higher.
Weather Sealing
Thanks to the weather-sealed body of the WG-2 GPS, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the NX200.
LCD Screen Size and Features
Pentax WG-2 GPS and Samsung NX200's LCD screens have the same diagonal size of 3.00 inches.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
