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 Panasonic ZS7 and Pentax WG-2 GPS side-by-side from the front, back and top in their relative dimensions. Panasonic ZS7 has external dimensions of 103 x 60 x 33 mm (4.06 x 2.36 x 1.3″) and weighs 218 g (0.48 lb / 7.69 oz) (including batteries). 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).

Here is the back view size comparison of the Panasonic ZS7 and Pentax WG-2 GPS.
Now lets look at the top view comparison of Panasonic ZS7 and Pentax WG-2 GPS.
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 20g lighter than the Panasonic ZS7 but we don't think this will make a significant difference.

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 ZS7.
LCD Screen Size and Features
Panasonic ZS7 and Pentax WG-2 GPS'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.
