Size and weight is a big decision factor when you are trying to find the ideal camera for your needs.
In this section, We are going to illustrate Panasonic FX48 and Casio EX-FC150 side-by-side from the front, back and top in their relative dimensions. Panasonic FX48 has external dimensions of 95 x 53 x 22 mm (3.74 x 2.09 x 0.87″) and weighs 150 g (0.33 lb / 5.29 oz) (including batteries). Casio EX-FC150 has external dimensions of 99 x 58 x 28 mm (3.9 x 2.28 x 1.1″) and weighs 173 g (0.38 lb / 6.10 oz) (including batteries).
Below you can see the front view size comparison of Panasonic FX48 and Casio EX-FC150. Panasonic FX48 is clearly the smaller of the two cameras. Its body is 4mm narrower, 5mm shorter and 6mm thinner than Casio EX-FC150.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Panasonic FX48 is 23g lighter than the Casio EX-FC150 but we don't think this will make a significant difference.
