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-10 and Samsung SL820 side-by-side from the front, back and top in their relative dimensions. Pentax WG-10 has external dimensions of and weighs 167 g (including batteries). Samsung SL820 has external dimensions of 95 x 59 x 23 mm (3.74 x 2.32 x 0.91″) and weighs 168 g (0.37 lb / 5.93 oz) (including batteries).
Below you can see the front-view size comparison of the Pentax WG-10 and the Samsung SL820. Pentax WG-10 has the same height with Samsung SL820. On the other hand, with a width of 116mm, it is 21 wider and also with a thickness of 29mm, it is 6mm thicker than Samsung SL820.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Pentax WG-10 is 1g lighter than the Samsung SL820 but we don't think this will make a significant difference.
