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 Samsung HZ15W and Samsung ST65 side-by-side from the front, back and top in their relative dimensions. Samsung HZ15W has external dimensions of 105 x 61 x 37 mm (4.13 x 2.4 x 1.46″) and weighs 249 g (0.55 lb / 8.78 oz) (including batteries). Samsung ST65 has external dimensions of 92 x 53 x 17 mm (3.62 x 2.09 x 0.67″) and weighs (including batteries).
Below you can see the front-view size comparison of the Samsung HZ15W and the Samsung ST65. Samsung ST65 is clearly the smaller of the two cameras. Its body is 13mm narrower, 8mm shorter and 20mm thinner than Samsung HZ15W.
Here is the back view size comparison of the Samsung HZ15W and Samsung ST65.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Samsung ST65 is 249g lighter than the Samsung HZ15W but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Samsung HZ15W (WB550) nor Samsung ST65 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 HZ15W and Samsung ST65's LCD screens have the same diagonal size of 3.00 inches.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
