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 ST600 and Canon SX30 IS side-by-side from the front, back and top in their relative dimensions. Samsung ST600 has external dimensions of 104 x 60 x 20 mm (4.09 x 2.36 x 0.79″) and weighs 150 g (0.33 lb / 5.29 oz) (including batteries). Canon SX30 IS has external dimensions of 123 x 92 x 108 mm (4.84 x 3.62 x 4.25″) and weighs 601 g (1.32 lb / 21.20 oz) (including batteries).
Below you can see the front-view size comparison of the Samsung ST600 and the Canon SX30 IS. Samsung ST600 is clearly the smaller of the two cameras. Its body is 19mm narrower, 32mm shorter and 88mm thinner than Canon SX30 IS.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Samsung ST600 is significantly lighter (451g ) than the Canon SX30 IS which may become a big advantage especially on long walking trips.

Unfortunately neither the Samsung ST600 nor Canon PowerShot SX30 IS provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.
