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 Pentax VS20 and Canon SX50 HS side-by-side from the front, back and top in their relative dimensions. Pentax VS20 has external dimensions of 111 x 61 x 38 mm (4.37 x 2.4 x 1.5″) and weighs 235 g (0.52 lb / 8.29 oz) (including batteries). Canon SX50 HS has external dimensions of 123 x 87 x 106 mm (4.84 x 3.43 x 4.17″) and weighs 595 g (1.31 lb / 20.99 oz) (including batteries).
Below you can see the front-view size comparison of the Pentax VS20 and the Canon SX50 HS. Pentax VS20 is clearly the smaller of the two cameras. Its body is 12mm narrower, 26mm shorter and 68mm thinner than Canon SX50 HS.
Here is the back view size comparison of the Pentax VS20 and Canon SX50 HS.
Now lets look at the top view comparison of Pentax VS20 and Canon SX50 HS.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Pentax VS20 is significantly lighter (360g ) than the Canon SX50 HS which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Pentax Optio VS20 nor Canon PowerShot SX50 HS provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.
