The DP1s was manufactured 5 years prior to the A7R which is a fairly sizable gap as far as camera tech is concerned. The two cameras feature different body design with the Sigma DP1s being a Large Sensor Compact camera and the Sony A7R being a SLR-style mirrorless camera.

Before diving into a step-by-step comparison, here is a quick highlight of how the DP1s matches up vs the A7R in regards to portability, imaging, features and an overall mark.

Following is a preview of the gallery photos for Sigma DP1s and Sony Alpha A7R. The entire galleries are available at Sigma DP1s Gallery and Sony A7R Gallery.

In case you're going to travel with your camera frequently, you'll need to take into account its weight and dimensions.

In many cases, it is very hard to visualise the gap in sensor dimensions only by viewing specs. The image underneath will provide you a much better sense of the sensor sizes in the DP1s and A7R.

As you can plainly see, the 2 cameras come with different megapixels and different sensor dimensions. The DP1s because of its smaller sensor will make shooting shallower depth of field more difficult and the Sony A7R will result in greater detail due to its extra 31 Megapixels. Higher resolution will also enable you to crop pictures a good deal more aggressively. The more aged DP1s will be disadvantaged with regard to sensor innovation.
