Size and weight is a big decision factor when you are trying to find the ideal camera for your needs.
In this section, We are going to illustrate Canon SX20 IS and FujiFilm HS20 EXR side-by-side from the front, back and top in their relative dimensions. Canon SX20 IS has external dimensions of 128 x 88 x 87 mm (5.04 x 3.46 x 3.43″) and weighs 600 g (1.32 lb / 21.16 oz) (including batteries).

Below you can see the front view size comparison of Canon SX20 IS and FujiFilm HS20 EXR. Canon SX20 IS is clearly the smaller of the two cameras. Its body is 3mm narrower, 3mm shorter and 39mm thinner than FujiFilm HS20 EXR.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Canon SX20 IS is significantly lighter (130g ) than the FujiFilm HS20 EXR which may become a big advantage especially on long walking trips.
Unfortunately neither Canon PowerShot SX20 IS nor FujiFilm FinePix HS20 EXR (FinePix HS22 EXR) provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors.
