Sigma DP2s vs Sony A7

Following is a extensive assessment of the Sigma DP2s and Sony A7, former is a Large Sensor Compact while the other is a Pro Mirrorless by competitors Sigma and Sony. There exists a large gap between the image resolutions of the DP2s (5MP) and A7 (24MP) and the DP2s (APS-C) and A7 (Full frame) offer different sensor size.

The DP2s was introduced 4 years earlier than the A7 which is quite a serious difference as far as technology is concerned. Both of these cameras feature different body design with the Sigma DP2s being a Large Sensor Compact camera and the Sony A7 being a SLR-style mirrorless camera.

Before diving into a step-by-step comparison, here is a quick highlight of how the DP2s matches up against the A7 in the way of portability, imaging, features and an overall score.

If you're going to carry around your camera often, you'll need to think about its weight and proportions. The Sigma DP2s enjoys exterior measurements of 113mm x 60mm x 56mm (4.4" x 2.4" x 2.2") with a weight of 280 grams (0.62 lbs) and the Sony A7 has measurements of 127mm x 94mm x 48mm (5.0" x 3.7" x 1.9") having a weight of 474 grams (1.04 lbs).

Don't forget, the weight of an ILC will vary dependant on the lens you have at the time. The following is a front view overall size comparison of the DP2s versus the A7.

Considering dimensions and weight, the portability score of the DP2s and A7 is 86 and 78 respectively.

More often than not, it's tough to picture the contrast between sensor sizes just by looking at technical specs. The picture below may give you a far better sense of the sensor sizing in the DP2s and A7.

As you can tell, both of the cameras come with different megapixel count and different sensor sizes. The DP2s using its tinier sensor is going to make shooting shallow depth of field more difficult and the Sony A7 will give you extra detail using its extra 19 Megapixels. Greater resolution will also let you crop images a good deal more aggressively. The more aged DP2s is going to be disadvantaged with regard to sensor innovation.
