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 Olympus 7040 and Canon SX30 IS side-by-side from the front, back and top in their relative dimensions. Olympus 7040 has external dimensions of 95 x 56 x 26 mm (3.74 x 2.2 x 1.02″) and weighs 144 g (0.32 lb / 5.08 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 Olympus 7040 and the Canon SX30 IS. Olympus 7040 is clearly the smaller of the two cameras. Its body is 28mm narrower, 36mm shorter and 82mm 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.
Olympus 7040 is significantly lighter (457g ) than the Canon SX30 IS which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Olympus Stylus 7040 (mju 7040) 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.
