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 Sony T99 and Olympus TG-870 side-by-side from the front, back and top in their relative dimensions. Sony T99 has external dimensions of 93 x 56 x 17 mm (3.66 x 2.2 x 0.67″) and weighs 121 g (0.27 lb / 4.27 oz) (including batteries). 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).
Below you can see the front-view size comparison of the Sony T99 and the Olympus TG-870. Sony T99 is clearly the smaller of the two cameras. Its body is 20mm narrower, 8mm shorter and 11mm thinner than Olympus TG-870.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony T99 is significantly lighter (100g ) than the Olympus TG-870 which may become a big advantage especially on long walking trips.
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 T99.
LCD Screen Size and Features
Sony T99 and Olympus TG-870'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 Sony T99 has a fixed type screen which provides less flexibility in shooting positions compared to TG-870.
