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 Olympus TG-870 and Panasonic ZS40 side-by-side from the front, back and top in their relative dimensions. Olympus TG-870 has external dimensions of 113 x 64 x 28 mm (4.45 x 2.52 x 1.1″) and weighs 221 g (0.49 lb / 7.80 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).

Now lets look at the top view comparison of Olympus TG-870 and Panasonic ZS40.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Olympus TG-870 is 19g lighter than the Panasonic ZS40 but we don't think this will make a significant difference.
Weather Sealing
Thanks to the weather-sealed body of the TG-870, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the ZS40.
LCD Screen Size and Features
Olympus TG-870 and Panasonic ZS40's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Olympus TG-870 features a
Tilting screen where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels whereas the Panasonic ZS40 has a fixed type screen which provides less flexibility in shooting positions compared to TG-870.
