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 W830 and Samsung ST150F side-by-side from the front, back and top in their relative dimensions. Sony W830 has external dimensions of 93 x 52 x 23 mm (3.66 x 2.05 x 0.91″) and weighs 122 g (0.27 lb / 4.30 oz) (including batteries). Samsung ST150F has external dimensions of 94 x 58 x 18 mm (3.7 x 2.28 x 0.71″) and weighs 114 g (0.25 lb / 4.02 oz) (including batteries).
Below you can see the front-view size comparison of the Sony W830 and the Samsung ST150F. Sony W830 is 1mm narrower and 6mm shorter than Samsung ST150F but it is also 5mm thicker.
Here is the back view size comparison of the Sony W830 and Samsung ST150F.
Now lets look at the top view comparison of Sony W830 and Samsung ST150F.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Samsung ST150F is 8g lighter than the Sony W830 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Sony Cyber-shot DSC-W830 nor Samsung ST150F 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
Samsung ST150F's 3.00" LCD screen is slightly larger than Sony W830's 2.7" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
