Canon G7 X MIII vs Sigma DP1x

The following is a in-depth review of the Canon G7 X MIII and Sigma DP1x, both Large Sensor Compact digital cameras by manufacturers Canon and Sigma. There is a noticeable difference between the sensor resolutions of the G7 X MIII (20MP) and DP1x (5MP) and the G7 X MIII (1") and DP1x (APS-C) posses totally different sensor sizing.

The G7 X MIII was manufactured 9 years after the DP1x which is quite a sizable difference as far as tech is concerned. Both the cameras have the same body design (Large Sensor Compact).

Before delving straight to a detailed comparison, here is a brief view of how the G7 X MIII grades vs the DP1x for portability, imaging, features and an overall mark.

Below is a sample of the gallery pictures for Canon PowerShot G7 X Mark III & Sigma DP1x. The entire galleries are provided at Canon G7 X MIII Gallery & Sigma DP1x Gallery.

For anyone who is going to travel with your camera frequently, you'll have to factor in its weight and measurements. The Canon G7 X MIII comes with outside measurements of 105mm x 61mm x 41mm (4.1" x 2.4" x 1.6") along with a weight of 304 grams (0.67 lbs) and the Sigma DP1x has proportions of 113mm x 60mm x 50mm (4.4" x 2.4" x 2.0") having a weight of 250 grams (0.55 lbs).

Don't forget, the weight of an ILC will differ depending on the lens you have chosen at the time. Underneath is a front view size comparison of the G7 X MIII compared to the DP1x.

Taking into account size and weight, the portability grade of the G7 X MIII and DP1x is 88 and 88 respectively.

Generally, it's difficult to visualise the contrast between sensor dimensions merely by checking a spec sheet. The picture underneath should offer you a far better sense of the sensor measurements in the G7 X MIII and DP1x.

Clearly, both of the cameras provide different megapixel count and different sensor dimensions. The G7 X MIII due to its tinier sensor will make achieving shallower depth of field harder and the Canon G7 X MIII will give more detail due to its extra 15MP. Greater resolution can also let you crop images more aggressively. The newer G7 X MIII is going to have an advantage when it comes to sensor tech.
