Olympus E-M10 vs Pentax RZ18

In this article, we will be evaluating the Olympus E-M10 vs Pentax RZ18, one is a Entry-Level Mirrorless and the latter is a Small Sensor Superzoom by brands Olympus and Pentax. The sensor resolution of the E-M10 (16MP) and the RZ18 (16MP) is relatively close but the E-M10 (Four Thirds) and RZ18 (1/2.3") come with different sensor measurements.

The E-M10 was brought out 2 years after the RZ18 which is a fairly big gap as far as camera tech is concerned. Each of these cameras offer different body type with the Olympus E-M10 being a SLR-style mirrorless camera and the Pentax RZ18 being a Compact camera.

Before diving straight into a detailed comparison, below is a brief highlight of how the E-M10 matches up against the RZ18 when considering portability, imaging, features and an overall score.

Take into account, the weight of an Interchangeable Lens Camera will differ dependant on the lens you choose at the time. Here is the front view measurements comparison of the E-M10 and the RZ18.

Factoring in size and weight, the portability grade of the E-M10 and RZ18 is 82 and 92 respectively.

Usually, it is very hard to visualize the gap in sensor sizes merely by looking through technical specs. The image below may provide you a clearer sense of the sensor measurements in the E-M10 and RZ18.

As you can tell, the two cameras enjoy the same exact resolution albeit different sensor sizes. The E-M10 contains the bigger sensor which will make getting shallow DOF simpler. The more modern E-M10 provides a benefit when it comes to sensor innovation.
