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 W650 and Sony W690 side-by-side from the front, back and top in their relative dimensions. Sony W650 has external dimensions of 94 x 56 x 19 mm (3.7 x 2.2 x 0.75″) and weighs 124 g (0.27 lb / 4.37 oz) (including batteries). Sony W690 has external dimensions of 94 x 56 x 22 mm (3.7 x 2.2 x 0.87″) and weighs 142 g (0.31 lb / 5.01 oz) (including batteries).

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony W650 is 18g lighter than the Sony W690 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Sony Cyber-shot DSC-W650 nor Sony Cyber-shot DSC-W690 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 W650 and Sony W690's LCD screens have the same diagonal size of 3.00 inches.
