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 Canon G5 X and Panasonic ZS300 side-by-side from the front, back and top in their relative dimensions. Canon G5 X has external dimensions of 112 x 76 x 44 mm (4.41 x 2.99 x 1.73″) and weighs 353 g (0.78 lb / 12.45 oz) (including batteries). Panasonic ZS300 has external dimensions of 111 x 66 x 45 mm (4.37 x 2.6 x 1.77″) and weighs 337 g (0.74 lb / 11.89 oz) (including batteries).
Below you can see the front-view size comparison of the Canon G5 X and the Panasonic ZS300. Panasonic ZS300 is 1mm narrower and 10mm shorter than Canon G5 X but it is also 1mm thicker.

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Panasonic ZS300 is 16g lighter than the Canon G5 X but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Canon PowerShot G5 X nor Panasonic Lumix DC-ZS300 (Lumix DC-TZ300) 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
Canon G5 X and Panasonic ZS300's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Canon G5 X sports a
Fully Articulated screen which you can change the angle and position of the screen almost freely, making it possible to shoot from waist or over-the-head levels, and especially very useful for shooting selfies and video. Panasonic ZS300's LCD screen is a fixed type which provides almost no flexibility in shooting positions compared to G5 X.
