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 ZS1 and Samsung TL205 side-by-side from the front, back and top in their relative dimensions. Panasonic ZS1 has external dimensions of 103 x 60 x 33 mm (4.06 x 2.36 x 1.3″) and weighs 229 g (0.50 lb / 8.08 oz) (including batteries). Samsung TL205 has external dimensions of 99 x 59 x 20 mm (3.9 x 2.32 x 0.79″) and weighs 177 g (0.39 lb / 6.24 oz) (including batteries).
Below you can see the front-view size comparison of the Panasonic ZS1 and the Samsung TL205. Samsung TL205 is clearly the smaller of the two cameras. Its body is 4mm narrower, 1mm shorter and 13mm thinner than Panasonic ZS1.

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Samsung TL205 is significantly lighter (52g ) than the Panasonic ZS1 which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Panasonic Lumix DMC-ZS1 (Lumix DMC-TZ6) nor Samsung TL205 (PL100) provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

Panasonic ZS1 and Samsung TL205's LCD screens have the same diagonal size of 2.70 inches.
