Size and weight are big decision factors when you are trying to find the ideal camera for your needs.

Panasonic LS5 has external dimensions of 97 x 62 x 27 mm (3.82 x 2.44 x 1.06″) and weighs 126 g (0.28 lb / 4.44 oz) (including batteries). 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).

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.

LCD Screen Size and Features
Pentax WG-3's 3.00" LCD screen is slightly larger than Panasonic LS5's 2.7 screen.
