Now lets look at the top view comparison of Pentax XG-1 and Canon G3 X.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Pentax XG-1 is significantly lighter (166g ) than the Canon G3 X which may become a big advantage especially on long walking trips.
Weather Sealing
Thanks to the weather-sealed body of the G3 X, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the XG-1.
LCD Screen Size and Features
Canon G3 X's 3.20" LCD screen is slightly larger than Pentax XG-1's 3 screen.
In addition to the size advantage, Canon G3 X 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, Pentax XG-1 has a fixed type screen which provides less flexibility in shooting positions compared to G3 X.
