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 FZ80 and Sony H300 side-by-side from the front, back and top in their relative dimensions. 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). Sony H300 has external dimensions of 130 x 95 x 122 mm (5.1 x 3.74 x 4.81″) and weighs 590 g (1.30 lb / 20.81 oz) (including batteries).
Below you can see the front-view size comparison of the Panasonic FZ80 and the Sony H300. Panasonic FZ80 has the same height with Sony H300. On the other hand, with a width of 94mm, it is 1 narrower and also with a thickness of 119mm, it is 3mm thinner than Sony H300.
Here is the back view size comparison of the Panasonic FZ80 and Sony H300.
Now lets look at the top view comparison of Panasonic FZ80 and Sony H300.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony H300 is 26g lighter than the Panasonic FZ80 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Panasonic Lumix DMC-FZ80 (Lumix DMC-FZ82) nor Sony Cyber-shot DSC-H300 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
Panasonic FZ80 and Sony H300'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.
