Size and weight is a big decision factor when you are trying to find the ideal camera for your needs.
In this section, We are going to illustrate Canon G5 X and Sigma DP2 Quattro side-by-side from the front, back and top in their relative dimensions. Canon G5 X has external dimensions of 112 x 76 x 44 mm (4.41 x 2.99 x 1.73″) and weighs 353 g (0.78 lb / 12.45 oz) (including batteries).

Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Canon G5 X is 42g lighter than the Sigma DP2 Quattro but we don't think this will make a significant difference.
Unfortunately neither Canon PowerShot G5 X nor Sigma DP2 Quattro provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Canon G5 X and Sigma DP2 Quattro's LCD screens has the same diagonal size of 3".
On the other hand, Canon G5 X 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 G5 X.
