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 W320 and Canon SX30 IS side-by-side from the front, back and top in their relative dimensions. Sony W320 has external dimensions of 93 x 52 x 17 mm (3.66 x 2.05 x 0.67″) and weighs 117 g (0.26 lb / 4.13 oz) (including batteries). Canon SX30 IS has external dimensions of 123 x 92 x 108 mm (4.84 x 3.62 x 4.25″) and weighs 601 g (1.32 lb / 21.20 oz) (including batteries).
Below you can see the front-view size comparison of the Sony W320 and the Canon SX30 IS. Sony W320 is clearly the smaller of the two cameras. Its body is 30mm narrower, 40mm shorter and 91mm thinner than Canon SX30 IS.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony W320 is significantly lighter (484g ) than the Canon SX30 IS which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Sony Cyber-shot DSC-W320 nor Canon PowerShot SX30 IS provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Sony W320 and Canon SX30 IS's LCD screens have the same diagonal size of 2.70 inches.
On the other hand, Canon SX30 IS sports a
Fully Articulated screen which you can change the angle and position of the screen almost freely, making it possible to shoot from waist or over-the-head levels, and especially very useful for shooting selfies and video. Sony W320's LCD screen is a fixed type which provides almost no flexibility in shooting positions compared to SX30 IS.
