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 Sony a5000 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). Sony a5000 has external dimensions of 110 x 63 x 36 mm (4.33 x 2.48 x 1.42″) and weighs 269 g (0.59 lb / 9.49 oz) (including batteries).
Below you can see the front-view size comparison of the Pentax WG-2 GPS and the Sony a5000. Pentax WG-2 GPS is 2mm shorter and 6mm thinner than Sony a5000 but it is also 12mm wider. As you can tell, actually this is not a fair size comparison since Pentax WG-2 GPS has a built-in lens but Sony a5000 doesn't. Once you put a lens on a5000, its thickness will increase significantly.
Here is the back view size comparison of the Pentax WG-2 GPS and Sony a5000.
Now lets look at the top view comparison of Pentax WG-2 GPS and Sony a5000.
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 significantly lighter (71g ) than the Sony a5000 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 a5000, 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 a5000.
LCD Screen Size and Features
Pentax WG-2 GPS and Sony a5000's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Sony a5000 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 WG-2 GPS has a fixed type screen which provides less flexibility in shooting positions compared to a5000.
