Now lets look at the top view comparison of Olympus TG-4 and Pentax MX-1.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Olympus TG-4 is significantly lighter (144g ) than the Pentax MX-1 which may become a big advantage especially on long walking trips.
Weather Sealing
Thanks to the weather-sealed body of the TG-4, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the MX-1.
LCD Screen Size and Features
Olympus TG-4 and Pentax MX-1's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Pentax MX-1 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 Olympus TG-4 has a fixed type screen which provides less flexibility in shooting positions compared to MX-1.
