Leica Q3 vs Sigma DP1s

Let's look more closely at the Leica Q3 and Sigma DP1s, both Large Sensor Compact digital cameras by competitors Leica and Sigma. There exists a sizeable gap between the image resolutions of the Q3 (60MP) and DP1s (5MP) and the Q3 (Full frame) and DP1s (APS-C) offer different sensor size.

The Q3 was launched 13 years later than the DP1s and that is quite a large gap as far as technology is concerned. Both of the cameras feature the same body design (Large Sensor Compact).

Before getting into a detailed comparison, here is a brief view of how the Q3 grades against the DP1s when considering portability, imaging, features and an overall rating.

The following is a sample of the gallery pictures for Leica Q3 and Sigma DP1s. The complete galleries are viewable at Leica Q3 Gallery and Sigma DP1s Gallery.

If you are intending to carry your camera often, you need to take into account its weight and measurements. The Leica Q3 provides external measurements of 130mm x 80mm x 93mm (5.1" x 3.1" x 3.7") accompanied by a weight of 743 grams (1.64 lbs) while the Sigma DP1s has proportions of 109mm x 60mm x 31mm (4.3" x 2.4" x 1.2") along with a weight of 270 grams (0.60 lbs).

Bear in mind, the weight of an Interchangeable Lens Camera will change based on the lens you have chosen at that moment. The following is a front view scale comparison of the Q3 against the DP1s.

Using dimensions and weight, the portability score of the Q3 and DP1s is 60 and 90 respectively.

Typically, it can be tough to imagine the contrast between sensor sizing merely by looking at a spec sheet. The visual here should give you a better sense of the sensor measurements in the Q3 and DP1s.

As you can see, the two cameras feature different resolutions and different sensor sizing. The Q3 due to its larger sensor is going to make achieving shallower DOF simpler and the Leica Q3 will give extra detail utilizing its extra 55MP. Greater resolution will make it easier to crop photos way more aggressively. The more recent Q3 should have an edge when it comes to sensor tech.
