Let's look more closely at the Olympus E-1 and Sigma DP1s, former is a Pro DSLR while the latter is a Large Sensor Compact by rivals Olympus and Sigma. The resolution of the E-1 (5MP) and the DP1s (5MP) is relatively close but the E-1 (Four Thirds) and DP1s (APS-C) provide different sensor dimensions.

The E-1 was released 6 years earlier than the DP1s which is a fairly serious difference as far as camera tech is concerned. Each of these cameras feature different body design with the Olympus E-1 being a Large SLR camera and the Sigma DP1s being a Large Sensor Compact camera.

Before we go into a comprehensive comparison, here is a short summation of how the E-1 matches up versus the DP1s in relation to portability, imaging, features and an overall mark.

Here is a preview of the gallery photos for Olympus E-1 & Sigma DP1s. The complete galleries are viewable at Olympus E-1 Gallery & Sigma DP1s Gallery.

In case you're intending to travel with your camera often, you need to consider its weight and dimensions.

Usually, its hard to visualize the gap in sensor dimensions just by looking through technical specs. The pic here might offer you a much better sense of the sensor dimensions in the E-1 and DP1s.

As you can tell, both of those cameras feature the identical resolution albeit different sensor dimensions. The E-1 has the smaller sensor which should make achieving bokeh harder. The more aged E-1 will be behind when it comes to sensor tech.
