Ricoh G900 vs Sigma DP2s

Here, we will be analyzing the Ricoh G900 and Sigma DP2s, one is a Waterproof and the latter is a Large Sensor Compact by manufacturers Ricoh and Sigma. There exists a huge gap between the resolutions of the G900 (20MP) and DP2s (5MP) and the G900 (1/2.3") and DP2s (APS-C) posses totally different sensor sizes.

The G900 was announced 8 years after the DP2s which is quite a significant gap as far as technology is concerned. Both of the cameras feature different body design with the Ricoh G900 being a Compact camera and the Sigma DP2s being a Large Sensor Compact camera.

Before delving straight to a detailed comparison, here is a simple synopsis of how the G900 scores vs the DP2s for portability, imaging, features and an overall score.

The following is a preview of the gallery images for Ricoh G900 and Sigma DP2s. The whole galleries are provided at Ricoh G900 Gallery and Sigma DP2s Gallery.

In case you're intending to carry around your camera, you need to factor its weight and measurements. The Ricoh G900 enjoys exterior measurements of 118mm x 66mm x 33mm (4.6" x 2.6" x 1.3") accompanied by a weight of 247 grams (0.54 lbs) while the Sigma DP2s has proportions of 113mm x 60mm x 56mm (4.4" x 2.4" x 2.2") with a weight of 280 grams (0.62 lbs).

Do not forget, the weight of an Interchangeable Lens Camera will differ dependant on the lens you have attached at that moment. Here is a front view scale comparison of the G900 compared to the DP2s.

Looking at dimensions and weight, the portability rating of the G900 and DP2s is 89 and 86 respectively.

More often than not, it is very hard to envision the difference between sensor sizes simply by going over a spec sheet. The pic underneath might provide you a stronger sense of the sensor measurements in the G900 and DP2s.

As you can see, both the cameras feature different megapixels and different sensor sizes. The G900 having a tinier sensor will make shooting shallower depth of field trickier and the Ricoh G900 will deliver greater detail with its extra 15 Megapixels. Higher resolution can also enable you to crop shots way more aggressively. The fresher G900 will have an edge in sensor innovation.
