Olympus E-P3 vs Pentax H90

Here is a extended review of the Olympus E-P3 versus Pentax H90, former being a Entry-Level Mirrorless while the latter is a Small Sensor Compact by competitors Olympus and Pentax. The image resolution of the E-P3 (12MP) and the H90 (12MP) is pretty comparable but the E-P3 (Four Thirds) and H90 (1/2.3") have totally different sensor size.

The E-P3 was manufactured 19 months later than the H90 which makes them a generation apart from one another. Each of the cameras feature different body design with the Olympus E-P3 being a Rangefinder-style mirrorless camera and the Pentax H90 being a Compact camera.

Before getting straight to a complete comparison, here is a short synopsis of how the E-P3 matches up against the H90 in terms of portability, imaging, features and an overall rating.

Keep in mind, the weight of an ILC will change based on the lens you have chosen at that time. Following is a front view dimensions comparison of the E-P3 versus the H90.

Looking at dimensions and weight, the portability score of the E-P3 and H90 is 86 and 93 respectively.

Quite often, it's tough to envision the gap in sensor sizing just by seeing technical specs. The visual here might offer you a much better sense of the sensor sizing in the E-P3 and H90.

As you can tell, each of these cameras come with the identical megapixel count albeit not the same sensor sizing. The E-P3 has the bigger sensor which is going to make obtaining shallower DOF easier. The fresher E-P3 will have an advantage in sensor innovation.
