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 Sony WX500 and Pentax WG-3 GPS side-by-side from the front, back and top in their relative dimensions. Sony WX500 has external dimensions of 102 x 58 x 36 mm (4.02 x 2.28 x 1.42″) and weighs 236 g (0.52 lb / 8.32 oz) (including batteries). Pentax WG-3 GPS has external dimensions of 125 x 64 x 33 mm (4.9 x 2.5 x 1.3″) and weighs 238 g (0.52 lb / 8.40 oz) (including batteries).
Below you can see the front-view size comparison of the Sony WX500 and the Pentax WG-3 GPS. Sony WX500 is 23mm narrower and 6mm shorter than Pentax WG-3 GPS but it is also 3mm thicker.
Here is the back view size comparison of the Sony WX500 and Pentax WG-3 GPS.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony WX500 is 2g lighter than the Pentax WG-3 GPS but we don't think this will make a significant difference.
Weather Sealing
Thanks to the weather-sealed body of the WG-3 GPS, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the WX500.
LCD Screen Size and Features
Sony WX500 and Pentax WG-3 GPS's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Sony WX500 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-3 GPS has a fixed type screen which provides less flexibility in shooting positions compared to WX500.
