Canon 400D vs Sigma DP1s

Lets look a bit more closely at the Canon 400D versus Sigma DP1s, one is a Entry-Level DSLR and the latter is a Large Sensor Compact by manufacturers Canon and Sigma. There is a huge difference between the resolutions of the 400D (10MP) and DP1s (5MP) but both cameras posses the same sensor sizing (APS-C).

Photography Glossary

The 400D was introduced 4 years prior to the DP1s which is quite a significant gap as far as tech is concerned. Each of the cameras have different body design with the Canon 400D being a Compact SLR camera and the Sigma DP1s being a Large Sensor Compact camera.

Before going into a thorough comparison, here is a simple highlight of how the 400D grades against the DP1s with respect to portability, imaging, features and an overall score.

This is a preview of the gallery images for Canon EOS 400D and Sigma DP1s. The whole galleries are viewable at Canon 400D Gallery and Sigma DP1s Gallery.

For anybody who is planning to carry around your camera frequently, you need to think about its weight and dimensions. The Canon 400D has got physical dimensions of 127mm x 94mm x 65mm (5.0" x 3.7" x 2.6") having a weight of 556 grams (1.23 lbs) and the Sigma DP1s has dimensions of 109mm x 60mm x 31mm (4.3" x 2.4" x 1.2") and a weight of 270 grams (0.60 lbs).

Take a look at the Canon 400D versus Sigma DP1s in the new Camera with Lens Size Comparison Tool.

Do not forget, the weight of an Interchangeable Lens Camera will change depending on the lens you use during that time. Here is a front view measurement comparison of the 400D and the DP1s.

Taking into account size and weight, the portability rating of the 400D and DP1s is 69 and 90 respectively.

Generally, it's difficult to see the contrast between sensor sizes just by reading technical specs. The image below should give you a better sense of the sensor sizes in the 400D and DP1s.

As you can tell, the 2 cameras provide the same sensor dimensions albeit not the same resolution. You should expect the Canon 400D to offer you more detail using its extra 5 Megapixels. Higher resolution will also enable you to crop shots more aggressively. The more aged 400D is going to be disadvantaged when it comes to sensor tech.
