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 Casio EX-ZR300 and Panasonic LF1 side-by-side from the front, back and top in their relative dimensions. Casio EX-ZR300 has external dimensions of 105 x 59 x 29 mm (4.13 x 2.32 x 1.14″) and weighs 205 g (0.45 lb / 7.23 oz) (including batteries). Panasonic LF1 has external dimensions of 103 x 62 x 28 mm (4.06 x 2.44 x 1.1″) and weighs 192 g (0.42 lb / 6.77 oz) (including batteries).

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Panasonic LF1 is 13g lighter than the Casio EX-ZR300 but we don't think this will make a significant difference.
