The E-P2 was revealed 5 years prior to the K-3 which is a fairly sizable difference as far as camera tech is concerned. The two cameras feature different body design with the Olympus E-P2 being a Rangefinder-style mirrorless camera and the Pentax K-3 being a Mid-size SLR camera.

Before going straight to a full comparison, here is a simple overview of how the E-P2 matches up against the K-3 with respect to portability, imaging, features and an overall score.

This is a preview of the gallery images for Olympus PEN E-P2 & Pentax K-3. The full galleries are provided at Olympus E-P2 Gallery & Pentax K-3 Gallery.

In case you're going to carry around your camera, you'll have to take into account its weight and measurements.

Always remember, the weight of an ILC will change based on the lens you are utilising at that time. The following is a front view measurements comparison of the E-P2 against the K-3.

Usually, it is difficult to visualise the difference in sensor sizes merely by viewing a spec sheet. The pic here will help provide you a more clear sense of the sensor measurements in the E-P2 and K-3.

Clearly, both the cameras feature different megapixels and different sensor sizes. The E-P2 with its smaller sensor will make getting shallower DOF trickier and the Pentax K-3 will render more detail because of its extra 12 Megapixels. Higher resolution will help you crop shots way more aggressively. The more aged E-P2 will be behind in sensor tech.
