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 Panasonic LX100 and Sony HX9V side-by-side from the front, back and top in their relative dimensions. Panasonic LX100 has external dimensions of 115 x 66 x 55 mm (4.53 x 2.6 x 2.17″) and weighs 393 g (0.87 lb / 13.86 oz) (including batteries).

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.

Panasonic LX100 and Sony HX9V's LCD screens have the same diagonal size of 3.00 inches.
