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 Sigma DP2 Quattro and Canon M6 side-by-side from the front, back and top in their relative dimensions. 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). Canon M6 has external dimensions of 112 x 68 x 45 mm (4.41 x 2.68 x 1.77″) and weighs 390 g (0.86 lb / 13.76 oz) (including batteries).
Below you can see the front-view size comparison of the Sigma DP2 Quattro and the Canon M6. Canon M6 is 49mm narrower and 37mm thinner than Sigma DP2 Quattro but it is also 1mm taller. As you can tell, actually this is not a fair size comparison since Sigma DP2 Quattro has a built-in lens but Canon M6 doesn't. Once you put a lens on M6, its thickness will increase significantly.
Here is the back view size comparison of the Sigma DP2 Quattro and Canon M6.
Now lets look at the top view comparison of Sigma DP2 Quattro and Canon M6.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon M6 is 5g lighter than the Sigma DP2 Quattro but we don't think this will make a significant difference.
Again, this comparison may not be very useful in real life as we are comparing the weight of a camera with a built-in lens to the body-only weight of an interchangeable lens camera. Once you put a lens on M6, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither the Sigma DP2 Quattro nor Canon EOS M6 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Sigma DP2 Quattro and Canon M6's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Canon M6 features a
Tilting screen where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels whereas the Sigma DP2 Quattro has a fixed type screen which provides less flexibility in shooting positions compared to M6.
