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 Samsung WB850F and Panasonic ZS40 side-by-side from the front, back and top in their relative dimensions. Samsung WB850F has external dimensions of and weighs 250 g (0.55 lb / 8.82 oz) (including batteries). Panasonic ZS40 has external dimensions of 111 x 64 x 34 mm (4.37 x 2.52 x 1.34″) and weighs 240 g (0.53 lb / 8.47 oz) (including batteries).
Below you can see the front-view size comparison of the Samsung WB850F and the Panasonic ZS40. Samsung WB850F is clearly the smaller of the two cameras. Its body is 2mm narrower, 2mm shorter and 9mm thinner than Panasonic ZS40.
Here is the back view size comparison of the Samsung WB850F and Panasonic ZS40.
Now lets look at the top view comparison of Samsung WB850F and Panasonic ZS40.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Panasonic ZS40 is 10g lighter than the Samsung WB850F but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Samsung WB850F nor Panasonic Lumix DMC-ZS40 (Lumix DMC-TZ60) provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

Samsung WB850F and Panasonic ZS40's LCD screens have the same diagonal size of 3.00 inches.
