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 HX10V and Panasonic ZS40 side-by-side from the front, back and top in their relative dimensions. Sony HX10V has external dimensions of 105 x 60 x 34 mm (4.13 x 2.36 x 1.34″) and weighs 234 g (0.52 lb / 8.25 oz) (including batteries). Panasonic ZS40 has external dimensions of 111 x 64 x 34 mm (4.37 x 2.52 x 1.34″) and weighs 240 g (0.53 lb / 8.47 oz) (including batteries).

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony HX10V is 6g lighter than the Panasonic ZS40 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Sony Cyber-shot DSC-HX10V nor Panasonic Lumix DMC-ZS40 (Lumix DMC-TZ60) 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 HX10V and Panasonic ZS40'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.
