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 HX9V and Sony HX7V side-by-side from the front, back and top in their relative dimensions. Sony HX9V has external dimensions of 105 x 59 x 34 mm (4.13 x 2.32 x 1.34″) and weighs 245 g (0.54 lb / 8.64 oz) (including batteries).

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony HX7V is significantly lighter (37g ) than the Sony HX9V which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Sony Cyber-shot DSC-HX9V nor Sony Cyber-shot DSC-HX7V provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

Sony HX9V and Sony HX7V's LCD screens have the same diagonal size of 3.00 inches.
