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 Olympus SH-1 and Pentax WG-1 GPS side-by-side from the front, back and top in their relative dimensions. Olympus SH-1 has external dimensions of 109 x 63 x 42 mm (4.29 x 2.48 x 1.65″) and weighs 271 g (0.60 lb / 9.56 oz) (including batteries). Pentax WG-1 GPS has external dimensions of 116 x 59 x 29 mm (4.55 x 2.3 x 1.12″) and weighs 167 g (0.37 lb / 5.89 oz) (including batteries).

Now lets look at the top view comparison of Olympus SH-1 and Pentax WG-1 GPS.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Pentax WG-1 GPS is significantly lighter (104g ) than the Olympus SH-1 which may become a big advantage especially on long walking trips.
Weather Sealing
Thanks to the weather-sealed body of the WG-1 GPS, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the SH-1.
LCD Screen Size and Features
Olympus SH-1's 3.00" LCD screen is slightly larger than Pentax WG-1 GPS's 2.7" screen.
