Canon SX1 IS vs Sigma DP2x

Following is a thorough review of the Canon SX1 IS versus Sigma DP2x, one is a Small Sensor Superzoom and the other is a Large Sensor Compact by manufacturers Canon and Sigma. There exists a huge gap among the sensor resolutions of the SX1 IS (10MP) and DP2x (5MP) and the SX1 IS (1/2.3") and DP2x (APS-C) enjoy totally different sensor measurements.

The SX1 IS was revealed 22 months prior to the DP2x making the cameras a generation away from one another. Both of the cameras come with different body type with the Canon SX1 IS being a SLR-like (bridge) camera and the Sigma DP2x being a Large Sensor Compact camera.

Before delving through a in depth comparison, below is a brief summation of how the SX1 IS matches up against the DP2x in regards to portability, imaging, features and an overall score.

The following is a sample of the gallery pictures for Canon PowerShot SX1 IS and Sigma DP2x. The full galleries are viewable at Canon SX1 IS Gallery and Sigma DP2x Gallery.

For those who are aiming to carry around your camera often, you'll need to consider its weight and volume.

Remember, the weight of an Interchangeable Lens Camera will change depending on the lens you use at that time. Below is the front view proportions comparison of the SX1 IS compared to the DP2x.

Looking at dimensions and weight, the portability score of the SX1 IS and DP2x is 64 and 86 respectively.

Quite often, it is very hard to see the difference in sensor sizes merely by seeing technical specs. The picture below may offer you a stronger sense of the sensor dimensions in the SX1 IS and DP2x.

As you can tell, both of these cameras have got different resolutions and different sensor sizes. The SX1 IS having a smaller sensor will make getting shallower depth of field more difficult and the Canon SX1 IS will show extra detail because of its extra 5MP. Greater resolution will also allow you to crop photos much more aggressively. The more aged SX1 IS will be disadvantaged in sensor innovation.
