Olympus TG-870 vs Sigma DP1s

On this page, we will be comparing the Olympus TG-870 vs Sigma DP1s, one is a Ultracompact and the latter is a Large Sensor Compact by manufacturers Olympus and Sigma. There is a crucial difference among the resolutions of the TG-870 (16MP) and DP1s (5MP) and the TG-870 (1/2.3") and DP1s (APS-C) offer totally different sensor dimensions.

The TG-870 was introduced 6 years after the DP1s which is a fairly serious gap as far as camera tech is concerned. The two cameras have different body design with the Olympus TG-870 being a Ultracompact camera and the Sigma DP1s being a Large Sensor Compact camera.

Before delving into a comprehensive comparison, here is a simple summary of how the TG-870 scores versus the DP1s when considering portability, imaging, features and an overall score.

Don't forget, the weight of an Interchangeable Lens Camera will vary based on the lens you have attached at the time. The following is a front view physical size comparison of the TG-870 versus the DP1s.

Taking into consideration size and weight, the portability rating of the TG-870 and DP1s is 91 and 90 respectively.

Often, its hard to visualise the contrast in sensor sizes just by going through a spec sheet. The pic below will help give you a more clear sense of the sensor sizing in the TG-870 and DP1s.

Clearly, the two cameras have different megapixels and different sensor sizes. The TG-870 using its smaller sensor will make achieving shallower depth of field tougher and the Olympus TG-870 will show greater detail using its extra 11MP. Higher resolution will also allow you to crop pictures a bit more aggressively. The fresher TG-870 will have an edge in sensor technology.
