Olympus 7000 vs Sigma DP3 Merrill

Below is a thorough overview of the Olympus 7000 versus Sigma DP3 Merrill, one being a Small Sensor Compact and the latter is a Large Sensor Compact by companies Olympus and Sigma. The sensor resolution of the 7000 (12MP) and the DP3 Merrill (15MP) is relatively well matched but the 7000 (1/2.3") and DP3 Merrill (APS-C) come with totally different sensor size.

The 7000 was unveiled 5 years earlier than the DP3 Merrill and that is quite a big gap as far as tech is concerned. Both the cameras offer different body type with the Olympus 7000 being a Compact camera and the Sigma DP3 Merrill being a Large Sensor Compact camera.

Before we go straight into a complete comparison, below is a simple introduction of how the 7000 scores vs the DP3 Merrill in the way of portability, imaging, features and an overall grade.

Do not forget, the weight of an Interchangeable Lens Camera will change based on the lens you have chosen at the time. Following is the front view physical size comparison of the 7000 against the DP3 Merrill.

Taking into consideration size and weight, the portability score of the 7000 and DP3 Merrill is 94 and 83 respectively.

In many cases, its difficult to envision the difference between sensor measurements simply by checking a spec sheet. The graphic below will offer you a clearer sense of the sensor sizing in the 7000 and DP3 Merrill.

As you can see, both of those cameras enjoy different megapixels and different sensor measurements. The 7000 using its tinier sensor will make getting shallow DOF more difficult and the Sigma DP3 Merrill will resolve more detail having an extra 3 Megapixels. Higher resolution will also let you crop photographs far more aggressively. The older 7000 is going to be behind with regard to sensor tech.
