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-3 GPS and Panasonic ZS50 side-by-side from the front, back and top in their relative dimensions. 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). Panasonic ZS50 has external dimensions of 111 x 65 x 34 mm (4.37 x 2.56 x 1.34″) and weighs 243 g (0.54 lb / 8.57 oz) (including batteries).

Now lets look at the top view comparison of Pentax WG-3 GPS and Panasonic ZS50.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Pentax WG-3 GPS is 5g lighter than the Panasonic ZS50 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 ZS50.
LCD Screen Size and Features
Pentax WG-3 GPS and Panasonic ZS50'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.
