Canon SX1 IS vs Sigma DP1

Lets look much closer at the Canon SX1 IS and Sigma DP1, one being a Small Sensor Superzoom and the latter is a Large Sensor Compact by manufacturers Canon and Sigma. There exists a crucial gap between the image resolutions of the SX1 IS (10MP) and DP1 (5MP) and the SX1 IS (1/2.3") and DP1 (APS-C) provide totally different sensor dimensions.

The SX1 IS was introduced 11 months later than the DP1 which means that they are both of a similar generation. The two cameras have different body design with the Canon SX1 IS being a SLR-like (bridge) camera and the Sigma DP1 being a Large Sensor Compact camera.

Before diving into a more detailed comparison, here is a concise highlight of how the SX1 IS grades vs the DP1 with regard to portability, imaging, features and an overall grade.

Below is a preview of the gallery images for Canon PowerShot SX1 IS and Sigma DP1. The whole galleries are available at Canon SX1 IS Gallery and Sigma DP1 Gallery.

When you are planning to lug around your camera often, you will want to take into account its weight and volume. The Canon SX1 IS has got physical dimensions of 128mm x 88mm x 88mm (5.0" x 3.5" x 3.5") accompanied by a weight of 615 grams (1.36 lbs) and the Sigma DP1 has sizing of 113mm x 60mm x 50mm (4.4" x 2.4" x 2.0") having a weight of 270 grams (0.60 lbs).

Remember that, the weight of an Interchangeable Lens Camera will differ based on the lens you are employing at the time. Below is a front view proportions comparison of the SX1 IS and the DP1.

Factoring in dimensions and weight, the portability rating of the SX1 IS and DP1 is 64 and 87 respectively.

More often than not, it is tough to envision the contrast between sensor measurements only by going over technical specs. The photograph below may provide you a far better sense of the sensor sizes in the SX1 IS and DP1.

As you can tell, each of these cameras provide different megapixel count and different sensor measurements. The SX1 IS having a tinier sensor will make getting shallower DOF more challenging and the Canon SX1 IS will offer you extra detail using its extra 5MP. Higher resolution will also enable you to crop pictures more aggressively. The more recent SX1 IS will have an edge in sensor technology.
