Size and weight is a big decision factor when you are trying to find the ideal camera for your needs.
In this section, We are going to illustrate Panasonic FX48 and Sony S950 side-by-side from the front, back and top in their relative dimensions. Panasonic FX48 has external dimensions of 95 x 53 x 22 mm (3.74 x 2.09 x 0.87″) and weighs 150 g (0.33 lb / 5.29 oz) (including batteries). Sony S950 has external dimensions of 93 x 56 x 24 mm (3.66 x 2.2 x 0.94″) and weighs 167 g (0.37 lb / 5.89 oz) (including batteries).

Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Panasonic FX48 is 17g lighter than the Sony S950 but we don't think this will make a significant difference.
Unfortunately neither Panasonic Lumix DMC-FX48 (Lumix DMC-FX40) nor Sony Cyber-shot DSC-S950 provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors.
