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 Samsung TL225 and Casio EX-ZR400 side-by-side from the front, back and top in their relative dimensions. Samsung TL225 has external dimensions of 100 x 60 x 19 mm (3.94 x 2.36 x 0.75″) and weighs 187 g (0.41 lb / 6.60 oz) (including batteries). Casio EX-ZR400 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).

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Samsung TL225 is 18g lighter than the Casio EX-ZR400 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Samsung TL225 (ST550) nor Casio Exilim EX-ZR400 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

Samsung TL225's 3.50" LCD screen is slightly larger than Casio EX-ZR400's 3" screen.
