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 FX48 and Sony HX7V 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 HX7V has external dimensions of 102 x 58 x 29 mm (4.02 x 2.28 x 1.14″) and weighs 208 g (0.46 lb / 7.34 oz) (including batteries).
Below you can see the front-view size comparison of the Panasonic FX48 and the Sony HX7V. Panasonic FX48 is clearly the smaller of the two cameras. Its body is 7mm narrower, 5mm shorter and 7mm thinner than Sony HX7V.
Here is the back view size comparison of the Panasonic FX48 and Sony HX7V.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Panasonic FX48 is significantly lighter (58g ) than the Sony HX7V which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Panasonic Lumix DMC-FX48 (Lumix DMC-FX40) 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.

LCD Screen Size and Features
Sony HX7V's 3.00" LCD screen is slightly larger than Panasonic FX48's 2.5" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
