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 FZ80D and Pentax XG-1 side-by-side from the front, back and top in their relative dimensions. Panasonic FZ80D 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). Pentax XG-1 has external dimensions of 119 x 89 x 98 mm (4.69 x 3.5 x 3.84″) and weighs 567 g (1.25 lb / 20.00 oz) (including batteries).
Below you can see the front-view size comparison of the Panasonic FZ80D and the Pentax XG-1. Pentax XG-1 is clearly the smaller of the two cameras. Its body is 11mm narrower, 5mm shorter and 21mm thinner than Panasonic FZ80D.

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Pentax XG-1 is 49g lighter than the Panasonic FZ80D but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Panasonic Lumix DC-FZ80D (Lumix DC-FZ82D / Lumix DC-FZ85D) nor Pentax XG-1 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 FZ80D and Pentax XG-1'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.
