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 Canon SX520 HS 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). Canon SX520 HS has external dimensions of 120 x 82 x 92 mm (4.72 x 3.23 x 3.62″) and weighs 441 g (0.97 lb / 15.56 oz) (including batteries).
Below you can see the front-view size comparison of the Canon G3 X and the Canon SX520 HS. Canon SX520 HS is 3mm narrower and 13mm thinner than Canon G3 X but it is also 5mm taller.
Here is the back view size comparison of the Canon G3 X and Canon SX520 HS.
Now lets look at the top view comparison of Canon G3 X and Canon SX520 HS.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon SX520 HS is significantly lighter (292g ) 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 SX520 HS 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 Canon SX520 HS'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, Canon SX520 HS has a fixed type screen which provides less flexibility in shooting positions compared to G3 X.
