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 ELPH 150 IS and Sigma SD15 side-by-side from the front, back and top in their relative dimensions. Canon ELPH 150 IS has external dimensions of 95 x 57 x 24 mm (3.74 x 2.24 x 0.94″) and weighs 142 g (0.31 lb / 5.01 oz) (including batteries). Sigma SD15 has external dimensions of 144 x 107 x 81 mm (5.67 x 4.21 x 3.19″) and weighs 750 g (1.65 lb / 26.46 oz) (including batteries).
Below you can see the front view size comparison of Canon ELPH 150 IS and Sigma SD15. Canon ELPH 150 IS is clearly the smaller of the two cameras. Its body is 49mm narrower, 50mm shorter and 57mm thinner than Sigma SD15. As you can tell, actually this is not a fair size comparison since Canon ELPH 150 IS has a built-in lens but Sigma SD15 doesn't. Once you put a lens on SD15, its thickness will increase significantly.

Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Canon ELPH 150 IS is significantly lighter (608g ) than the Sigma SD15 which may become a big advantage especially on long walking trips.
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 SD15, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither Canon PowerShot ELPH 150 IS (IXUS 155) nor Sigma SD15 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
Sigma SD15's 3" LCD screen is slightly larger than Canon ELPH 150 IS's 2.7" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
Canon ELPH 150 IS has a 20.0MP 1/2.3" (6.17 x 4.55 mm ) sized CCD sensor and features Digic 4+ processor. On the other hand, Sigma SD15 has a 5.0MP APS-C (20.7 x 13.8 mm ) sized CMOS (Foveon X3) sensor and features True II processor.
Canon ELPH 150 IS's sensor provides 15MP more than Sigma SD15'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 ELPH 150 IS and SD15 sensor size comparison.

Sensor Size and Resolution Comparison image of Canon ELPH 150 IS and Sigma SD15 Cameras
As seen above, Sigma SD15 has a 10.2x Larger sensor area than Canon ELPH 150 IS. 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.
