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 SP-100 and Canon SX40 HS side-by-side from the front, back and top in their relative dimensions. Olympus SP-100 has external dimensions of 122 x 91 x 133 mm (4.8 x 3.6 x 5.25″) and weighs 594 g (1.31 lb / 20.95 oz) (including batteries). Canon SX40 HS has external dimensions of 123 x 92 x 108 mm (4.84 x 3.62 x 4.25″) and weighs 600 g (1.32 lb / 21.16 oz) (including batteries).
Below you can see the front-view size comparison of the Olympus SP-100 and the Canon SX40 HS. Olympus SP-100 is 1mm narrower and 1mm shorter than Canon SX40 HS but it is also 25mm thicker.
Here is the back view size comparison of the Olympus SP-100 and Canon SX40 HS.
Now lets look at the top view comparison of Olympus SP-100 and Canon SX40 HS.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Olympus SP-100 is 6g lighter than the Canon SX40 HS but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Olympus Stylus SP-100 nor Canon PowerShot SX40 HS provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.
