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 H400 and Panasonic FZ80 side-by-side from the front, back and top in their relative dimensions. Sony H400 has external dimensions of 130 x 95 x 122 mm (5.1 x 3.74 x 4.81″) and weighs 628 g (1.38 lb / 22.15 oz) (including batteries). Panasonic FZ80 has external dimensions of 130 x 94 x 119 mm (5.12 x 3.7 x 4.69″) and weighs 616 g (1.36 lb / 21.73 oz) (including batteries).
Below you can see the front-view size comparison of the Sony H400 and the Panasonic FZ80.
Here is the back view size comparison of the Sony H400 and Panasonic FZ80.
Now lets look at the top view comparison of Sony H400 and Panasonic FZ80.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Panasonic FZ80 is 12g lighter than the Sony H400 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Sony Cyber-shot DSC-H400 nor Panasonic Lumix DMC-FZ80 (Lumix DMC-FZ82) 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 H400 and Panasonic FZ80'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.
