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 A10.
LCD Screen Size and Features
Olympus TG-870's 3.00" LCD screen is slightly larger than Nikon A10'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, Nikon A10 has a fixed type screen which provides less flexibility in shooting positions compared to TG-870.
