Nikon D1 vs Sigma DP1s

The following is a extended analysis of the Nikon D1 and Sigma DP1s, one is a Pro DSLR and the other is a Large Sensor Compact by rivals Nikon and Sigma. There is a crucial difference among the sensor resolutions of the D1 (3MP) and DP1s (5MP) but both cameras posses the same sensor dimensions (APS-C).

The D1 was unveiled 9 years prior to the DP1s which is a fairly serious gap as far as camera tech is concerned. Both of the cameras have different body design with the Nikon D1 being a Large SLR camera and the Sigma DP1s being a Large Sensor Compact camera.

Before getting into a more detailed comparison, here is a brief synopsis of how the D1 grades vs the DP1s in relation to portability, imaging, features and an overall mark.

Following is a sample of the gallery pictures for Nikon D1 and Sigma DP1s. The full galleries are available at Nikon D1 Gallery and Sigma DP1s Gallery.

If you're looking to travel with your camera, you'll have to think about its weight and volume. The Nikon D1 offers external measurements of 157mm x 153mm x 85mm (6.2" x 6.0" x 3.3") having a weight of 1200 grams (2.65 lbs) whilst the Sigma DP1s has sizing of 109mm x 60mm x 31mm (4.3" x 2.4" x 1.2") accompanied by a weight of 270 grams (0.60 lbs).

Keep in mind, the weight of an Interchangeable Lens Camera will differ based on the lens you are working with at that time. Below is a front view size comparison of the D1 versus the DP1s.

Using size and weight, the portability score of the D1 and DP1s is 51 and 90 respectively.

Usually, it is very difficult to see the difference in sensor dimensions merely by viewing technical specs. The picture here may provide you a better sense of the sensor measurements in the D1 and DP1s.

As you can tell, both of those cameras provide the same sensor dimensions but not the same resolution. You should anticipate the Sigma DP1s to provide you with extra detail having an extra 2 Megapixels. Greater resolution can also make it easier to crop photos more aggressively. The more aged D1 will be disadvantaged when it comes to sensor tech.
