The DP1 was introduced 6 years before the A7R which is quite a big difference as far as technology is concerned. Each of these cameras feature different body design with the Sigma DP1 being a Large Sensor Compact camera and the Sony A7R being a SLR-style mirrorless camera.

Before we go right into a thorough comparison, here is a short synopsis of how the DP1 matches up vs the A7R with respect to portability, imaging, features and an overall mark.

Below is a preview of the gallery photos for Sigma DP1 & Sony Alpha A7R. The whole galleries are available at Sigma DP1 Gallery & Sony A7R Gallery.

For anybody who is planning to travel with your camera frequently, you're going to have to factor its weight and volume.

Do not forget, the weight of an ILC will vary based on the lens you have chosen during that time. The following is a front view dimension comparison of the DP1 versus the A7R.

Looking at dimensions and weight, the portability grade of the DP1 and A7R is 87 and 78 respectively.

More often than not, it is hard to visualize the gap between sensor dimensions simply by looking at specifications. The pic below will help give you a far better sense of the sensor measurements in the DP1 and A7R.

Plainly, both the cameras feature different megapixels and different sensor dimensions. The DP1 having a tinier sensor is going to make shooting shallower depth of field trickier and the Sony A7R will resolve greater detail using its extra 31 Megapixels. Higher resolution will also let you crop pictures way more aggressively. The more aged DP1 is going to be disadvantaged with regard to sensor tech.
