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 ZS100 and Sony ZV-1 side-by-side from the front, back and top in their relative dimensions. Panasonic ZS100 has external dimensions of 111 x 65 x 44 mm (4.37 x 2.56 x 1.73″) and weighs 312 g (0.69 lb / 11.01 oz) (including batteries). Sony ZV-1 has external dimensions of 105 x 60 x 44 mm (4.13 x 2.36 x 1.73″) and weighs 294 g (0.65 lb / 10.37 oz) (including batteries).
Below you can see the front-view size comparison of the Panasonic ZS100 and the Sony ZV-1. Sony ZV-1 is 6mm narrower and 5mm shorter than Panasonic ZS100 but they have the same thickness of 44mm.
Here is the back view size comparison of the Panasonic ZS100 and Sony ZV-1.
Now lets look at the top view comparison of Panasonic ZS100 and Sony ZV-1.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony ZV-1 is 18g lighter than the Panasonic ZS100 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Panasonic Lumix DMC-ZS100 (Lumix DMC-TZ100) nor Sony ZV-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 ZS100 and Sony ZV-1's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Sony ZV-1 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 ZS100's LCD screen is a fixed type which provides almost no flexibility in shooting positions compared to ZV-1.
