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 Sigma DP2 Quattro 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). Sigma DP2 Quattro has external dimensions of 161 x 67 x 82 mm (6.34 x 2.64 x 3.23″) and weighs 395 g (0.87 lb / 13.93 oz) (including batteries).
Below you can see the front-view size comparison of the Canon G1 X III and the Sigma DP2 Quattro. Canon G1 X III is 46mm narrower and 31mm thinner than Sigma DP2 Quattro but it is also 11mm taller.
Here is the back view size comparison of the Canon G1 X III and Sigma DP2 Quattro.
Now lets look at the top view comparison of Canon G1 X III and Sigma DP2 Quattro.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sigma DP2 Quattro is 4g lighter than the Canon G1 X III 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 DP2 Quattro which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Canon G1 X III and Sigma DP2 Quattro'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. Sigma DP2 Quattro's LCD screen is a fixed type which provides almost no flexibility in shooting positions compared to G1 X III.
