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 Sony TX20 and Canon SX40 HS side-by-side from the front, back and top in their relative dimensions. Sony TX20 has external dimensions of 96 x 56 x 18 mm (3.78 x 2.2 x 0.71″) and weighs 133 g (0.29 lb / 4.69 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).

Now lets look at the top view comparison of Sony TX20 and Canon SX40 HS.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony TX20 is significantly lighter (467g ) than the Canon SX40 HS which may become a big advantage especially on long walking trips.
