Sigma DP1x vs Sony A900

On this page, we will be comparing the Sigma DP1x and Sony A900, one being a Large Sensor Compact and the latter is a Advanced DSLR by brands Sigma and Sony. There exists a crucial gap among the image resolutions of the DP1x (5MP) and A900 (25MP) and the DP1x (APS-C) and A900 (Full frame) offer totally different sensor size.

The DP1x was brought out 17 months later than the A900 which makes them a generation apart from one another. Both the cameras have different body design with the Sigma DP1x being a Large Sensor Compact camera and the Sony A900 being a Mid-size SLR camera.

Before we go straight to a in depth comparison, here is a short synopsis of how the DP1x matches up against the A900 with respect to portability, imaging, features and an overall grade.

Following is a preview of the gallery images for Sigma DP1x and Sony Alpha DSLR-A900. The entire galleries are provided at Sigma DP1x Gallery and Sony A900 Gallery.

When you are looking to lug around your camera, you need to factor in its weight and proportions.

Keep in mind, the weight of an Interchangeable Lens Camera will change dependant on the lens you have attached during that time. Following is a front view overall size comparison of the DP1x against the A900.

Taking into consideration dimensions and weight, the portability score of the DP1x and A900 is 88 and 54 respectively.

Quite often, its hard to envision the gap in sensor measurements simply by researching a spec sheet. The visual underneath will provide you a more clear sense of the sensor dimensions in the DP1x and A900.

Clearly, both of those cameras have different megapixel count and different sensor measurements. The DP1x due to its smaller sensor will make getting shallower depth of field more difficult and the Sony A900 will render greater detail having its extra 20 Megapixels. Higher resolution can also make it easier to crop photographs a bit more aggressively. The more recent DP1x is going to have an advantage when it comes to sensor innovation.
