Sigma DP1s vs Sony A7S

In this article, we will be reviewing the Sigma DP1s and Sony A7S, former being a Large Sensor Compact while the latter is a Pro Mirrorless by brands Sigma and Sony. There exists a sizable gap among the image resolutions of the DP1s (5MP) and A7S (12MP) and the DP1s (APS-C) and A7S (Full frame) feature totally different sensor size.

The DP1s was announced 5 years prior to the A7S and that is a fairly significant difference as far as camera technology is concerned. Each of the cameras offer different body type with the Sigma DP1s being a Large Sensor Compact camera and the Sony A7S being a SLR-style mirrorless camera.

Before delving through a thorough comparison, below is a short view of how the DP1s matches up versus the A7S in regards to portability, imaging, features and an overall grade.

If you're going to lug around your camera frequently, you should think about its weight and proportions. The Sigma DP1s provides external dimensions of 109mm x 60mm x 31mm (4.3" x 2.4" x 1.2") having a weight of 270 grams (0.60 lbs) and the Sony A7S has measurements of 127mm x 94mm x 48mm (5.0" x 3.7" x 1.9") along with a weight of 489 grams (1.08 lbs).

Remember that, the weight of an ILC will vary dependant on the lens you select at that time. The following is the front view overall size comparison of the DP1s against the A7S.

Using dimensions and weight, the portability grade of the DP1s and A7S is 90 and 77 respectively.

Sometimes, its hard to envision the gap in sensor measurements simply by researching technical specs. The photograph underneath may offer you a clearer sense of the sensor sizes in the DP1s and A7S.

As you have seen, both of those cameras enjoy different megapixels and different sensor measurements. The DP1s using its smaller sensor will make shooting shallow depth of field tougher and the Sony A7S will result in extra detail with its extra 7 Megapixels. Higher resolution will also let you crop pictures far more aggressively. The older DP1s will be behind with regard to sensor innovation.
