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 G1 X III and Sigma DP1s 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 DP1s has external dimensions of 109 x 60 x 31 mm (4.29 x 2.36 x 1.22″) and weighs 270 g (0.60 lb / 9.52 oz) (including batteries).
Below you can see the front view size comparison of Canon G1 X III and Sigma DP1s. Sigma DP1s is clearly the smaller of the two cameras. Its body is 6mm narrower, 18mm shorter and 20mm thinner than Canon G1 X III.

Weather Sealing
With its weather sealed body, we believe that G1 X III has a big advantage over DP1s which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Canon G1 X III's 3 LCD screen is slightly larger than Sigma DP1s's 2.5" screen.
Moreover, 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. On the other hand, Sigma DP1s has a fixed type screen which provides almost no flexibility in shooting positions compared to G1 X III.
Canon G1 X III has a 24.0MP APS-C (22.3 x 14.9 mm ) sized CMOS sensor and features DIGIC 7 processor. On the other hand, Sigma DP1s has a 5.0MP APS-C (20.7 x 13.8 mm ) sized CMOS (Foveon X3) sensor .
Canon G1 X III's sensor provides 19MP more than Sigma DP1s's sensor, which gives a significant advantage in real life. You can print your images larger or crop more freely.
On the other hand, please keep in mind that Max sensor resolution is not the only determinant of resolving power. Factors such as the optical elements, low pass filter, pixel size and sensor technology also affects the final resolution of the captured image.
Below you can see the G1 X III and DP1s sensor size comparison.

Sensor Size and Resolution Comparison image of Canon G1 X III and Sigma DP1s Cameras
As seen above, Canon G1 X III has a 1.2x Larger sensor area than Sigma DP1s. Larger sensors give photographer more control on the depth of field and blurry background compared to smaller sensor when shot in same focal length and aperture.
Canon G1 X III features a 24-72 mm F2.8-5.6 3x zoom lens whereas Sigma DP1s features a 28 mm Prime lens.
It is not easy to compare a prime lens with a zoom lens. Canon G1 X III's zoom lens provides a great flexibility compared to Sigma DP1s's 28mm fixed focal length lens. On the other hand, DP1s's prime lens makes it a specialized camera. You compromise the flexibility of a zoom in order to enjoy the high image quality and unique rendering of this fast lens.
On the tele end, Canon G1 X III has 44mm longer reach than the Sigma DP1s. However, with a max aperture of f, Sigma DP1s is faster at tele end.
