Its time to look a bit more closely at the Sigma DP1s vs Sony A7, former being a Large Sensor Compact while the latter is a Pro Mirrorless by manufacturers Sigma and Sony. There exists a large gap between the resolutions of the DP1s (5MP) and A7 (24MP) and the DP1s (APS-C) and A7 (Full frame) come with different sensor size.

The DP1s was announced 5 years prior to the A7 and that is quite a serious difference as far as technology is concerned. Both cameras offer different body type with the Sigma DP1s being a Large Sensor Compact camera and the Sony A7 being a SLR-style mirrorless camera.

Before getting in to a step-by-step comparison, below is a short summation of how the DP1s matches up vs the A7 with respect to portability, imaging, features and an overall rating.

Below is a preview of the gallery images for Sigma DP1s & Sony Alpha A7. The whole galleries are provided at Sigma DP1s Gallery & Sony A7 Gallery.

More often than not, it is very difficult to visualize the contrast between sensor sizing just by checking technical specs. The graphic here will help give you a stronger sense of the sensor sizes in the DP1s and A7.

As you can tell, each of these cameras offer different megapixels and different sensor sizing. The DP1s having a tinier sensor is going to make getting bokeh harder and the Sony A7 will resolve greater detail with its extra 19MP. Higher resolution will also help you crop photographs a little more aggressively. The older DP1s is going to be disadvantaged when it comes to sensor tech.
