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 G1 X III and Canon SX540 HS side-by-side from the front, back and top in their relative dimensions. Canon G1 X III has external dimensions of 115 x 78 x 51 mm (4.53 x 3.07 x 2.01″) and weighs 399 g (0.88 lb / 14.07 oz) (including batteries). Canon SX540 HS has external dimensions of 120 x 82 x 92 mm (4.72 x 3.23 x 3.62″) and weighs 442 g (0.97 lb / 15.59 oz) (including batteries).
Below you can see the front-view size comparison of the Canon G1 X III and the Canon SX540 HS. Canon G1 X III is clearly the smaller of the two cameras. Its body is 5mm narrower, 4mm shorter and 41mm thinner than Canon SX540 HS.
Here is the back view size comparison of the Canon G1 X III and Canon SX540 HS.
Now lets look at the top view comparison of Canon G1 X III and Canon SX540 HS.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon G1 X III is 43g lighter than the Canon SX540 HS but we don't think this will make a significant difference.
Weather Sealing
With its weather-sealed body, we believe that the G1 X III has a big advantage over the SX540 HS which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Canon G1 X III and Canon SX540 HS's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Canon G1 X III sports a
Fully Articulated screen which you can change the angle and position of the screen almost freely, making it possible to shoot from waist or over-the-head levels, and especially very useful for shooting selfies and video. Canon SX540 HS's LCD screen is a fixed type which provides almost no flexibility in shooting positions compared to G1 X III.
