Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.

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 EX-S7.
LCD Screen Size and Features
Olympus TG-870's 3.00" LCD screen is slightly larger than Casio EX-S7's 2.7" screen.
In addition to the size advantage, Olympus TG-870 LCD screen also has a
Tilting feature where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels. On the other hand, Casio EX-S7 has a fixed type screen which provides less flexibility in shooting positions compared to TG-870.
