Casio EX-S5 vs Sigma DP1s

Below is a in-depth comparison of the Casio EX-S5 and Sigma DP1s, one being a Ultracompact and the latter is a Large Sensor Compact by competitors Casio and Sigma. There is a big difference among the sensor resolutions of the EX-S5 (9MP) and DP1s (5MP) and the EX-S5 (1/2.3") and DP1s (APS-C) offer totally different sensor dimensions.

The EX-S5 was introduced 8 months earlier than the DP1s which means that they are both of a similar generation. Each of the cameras have different body design with the Casio EX-S5 being a Ultracompact camera and the Sigma DP1s being a Large Sensor Compact camera.

Before going straight to a complete comparison, here is a quick highlight of how the EX-S5 scores vs the DP1s with respect to portability, imaging, features and an overall grade.

If you're intending to lug around your camera regularly, you should consider its weight and dimensions. The Casio EX-S5 features outside measurements of 102mm x 35mm x 22mm (4.0" x 1.4" x 0.9") accompanied by a weight of 100 grams (0.22 lbs) and the Sigma DP1s has dimensions of 109mm x 60mm x 31mm (4.3" x 2.4" x 1.2") and a weight of 270 grams (0.60 lbs).

Bear in mind, the weight of an Interchangeable Lens Camera will change depending on the lens you have attached during that time. Below is a front view size comparison of the EX-S5 against the DP1s.

Using size and weight, the portability score of the EX-S5 and DP1s is 97 and 90 respectively.

Generally, it is tough to visualise the difference in sensor measurements simply by researching specifications. The visual below should provide you a clearer sense of the sensor measurements in the EX-S5 and DP1s.

To sum up, each of these cameras have different megapixel count and different sensor measurements. The EX-S5 using its smaller sensor will make shooting shallow DOF more difficult and the Casio EX-S5 will result in more detail using its extra 4MP. Higher resolution will also enable you to crop pictures a bit more aggressively. The older EX-S5 will be behind when it comes to sensor technology.
