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 PL170 and Canon SX40 HS side-by-side from the front, back and top in their relative dimensions. Samsung PL170 has external dimensions of 95 x 57 x 19 mm (3.74 x 2.24 x 0.75″) and weighs (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 Samsung PL170 and the Canon SX40 HS. Samsung PL170 is clearly the smaller of the two cameras. Its body is 28mm narrower, 35mm shorter and 89mm thinner than Canon SX40 HS.
Here is the back view size comparison of the Samsung PL170 and Canon SX40 HS.
Now lets look at the top view comparison of Samsung PL170 and Canon SX40 HS.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Samsung PL170 is 600g lighter than the Canon SX40 HS but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Samsung PL170 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.
