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 and FujiFilm F80EXR side-by-side from the front, back and top in their relative dimensions. Pentax WG-3 has external dimensions of 124 x 64 x 33 mm (4.9 x 2.5 x 1.3″) and weighs 230 g (0.51 lb / 8.11 oz) (including batteries). FujiFilm F80EXR has external dimensions of 99 x 59 x 28 mm (3.9 x 2.32 x 1.1″) and weighs 210 g (0.46 lb / 7.41 oz) (including batteries).
Below you can see the front-view size comparison of the Pentax WG-3 and the FujiFilm F80EXR. FujiFilm F80EXR is clearly the smaller of the two cameras. Its body is 25mm narrower, 5mm shorter and 5mm thinner than Pentax WG-3.
Here is the back view size comparison of the Pentax WG-3 and FujiFilm F80EXR.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
FujiFilm F80EXR is 20g lighter than the Pentax WG-3 but we don't think this will make a significant difference.
Weather Sealing
Thanks to the weather-sealed body of the WG-3, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the F80EXR.
LCD Screen Size and Features
Pentax WG-3 and FujiFilm F80EXR'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.
