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 ZV-1 II and Panasonic ZS300 side-by-side from the front, back and top in their relative dimensions. Sony ZV-1 II has external dimensions of 106 x 60 x 47 mm (4.15 x 2.36 x 1.84″) and weighs 292 g (0.64 lb / 10.30 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 Sony ZV-1 II and the Panasonic ZS300. Sony ZV-1 II is 5mm narrower and 6mm shorter than Panasonic ZS300 but it is also 2mm thicker.

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony ZV-1 II is 45g lighter than the Panasonic ZS300 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Sony ZV-1 Mark II 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
Sony ZV-1 II and Panasonic ZS300's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Sony ZV-1 II 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 ZV-1 II.
