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 Samsung ST6500 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). Samsung ST6500 has external dimensions of 102 x 57 x 19 mm (4.02 x 2.24 x 0.75″) and weighs (including batteries).
Below you can see the front-view size comparison of the Panasonic ZS100 and the Samsung ST6500. Samsung ST6500 is clearly the smaller of the two cameras. Its body is 9mm narrower, 8mm shorter and 25mm thinner than Panasonic ZS100.
Here is the back view size comparison of the Panasonic ZS100 and Samsung ST6500.
Now lets look at the top view comparison of Panasonic ZS100 and Samsung ST6500.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Samsung ST6500 is 312g 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 Samsung ST6500 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 Samsung ST6500's LCD screens have the same diagonal size of 3.00 inches.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
