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 Canon G3 X and Sony H300 side-by-side from the front, back and top in their relative dimensions. Canon G3 X has external dimensions of 123 x 77 x 105 mm (4.84 x 3.03 x 4.13″) and weighs 733 g (1.62 lb / 25.86 oz) (including batteries). Sony H300 has external dimensions of 130 x 95 x 122 mm (5.1 x 3.74 x 4.81″) and weighs 590 g (1.30 lb / 20.81 oz) (including batteries).

Here is the back view size comparison of the Canon G3 X and Sony H300.
Now lets look at the top view comparison of Canon G3 X and Sony H300.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony H300 is significantly lighter (143g ) than the Canon G3 X which may become a big advantage especially on long walking trips.
Weather Sealing
With its weather-sealed body, we believe that the G3 X has a big advantage over the H300 which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Canon G3 X's 3.20" LCD screen is slightly larger than Sony H300'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, Sony H300 has a fixed type screen which provides less flexibility in shooting positions compared to G3 X.
