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 Canon S100 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). Canon S100 has external dimensions of 99 x 60 x 28 mm (3.9 x 2.36 x 1.1″) and weighs 198 g (0.44 lb / 6.98 oz) (including batteries).
Below you can see the front-view size comparison of the Olympus TG-870 and the Canon S100. Canon S100 is 14mm narrower and 4mm shorter than Olympus TG-870 but they have the same thickness of 28mm.
Here is the back view size comparison of the Olympus TG-870 and Canon S100.
Now lets look at the top view comparison of Olympus TG-870 and Canon S100.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon S100 is 23g lighter than the Olympus TG-870 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 S100.
LCD Screen Size and Features
Olympus TG-870 and Canon S100'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 Canon S100 has a fixed type screen which provides less flexibility in shooting positions compared to TG-870.
