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 ZS20 and Panasonic TS4 side-by-side from the front, back and top in their relative dimensions. Panasonic ZS20 has external dimensions of 105 x 59 x 28 mm (4.13 x 2.32 x 1.1″) and weighs 206 g (0.45 lb / 7.27 oz) (including batteries). Panasonic TS4 has external dimensions of 103 x 64 x 27 mm (4.06 x 2.52 x 1.06″) and weighs 197 g (0.43 lb / 6.95 oz) (including batteries).
Below you can see the front-view size comparison of the Panasonic ZS20 and the Panasonic TS4. Panasonic TS4 is 2mm narrower and 1mm thinner than Panasonic ZS20 but it is also 5mm taller.
Here is the back view size comparison of the Panasonic ZS20 and Panasonic TS4.
Now lets look at the top view comparison of Panasonic ZS20 and Panasonic TS4.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Panasonic TS4 is 9g lighter than the Panasonic ZS20 but we don't think this will make a significant difference.
Weather Sealing
Thanks to the weather-sealed body of the TS4, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the ZS20.
LCD Screen Size and Features
Panasonic ZS20's 3.00" LCD screen is slightly larger than Panasonic TS4's 2.7" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
