The E-PL1s was revealed 3 years before the K-5 II which is quite a big gap as far as tech is concerned. Both cameras have different body design with the Olympus E-PL1s being a Rangefinder-style mirrorless camera and the Pentax K-5 II being a Mid-size SLR camera.

Before we go right into a more detailed comparison, here is a brief synopsis of how the E-PL1s matches up vs the K-5 II in the way of portability, imaging, features and an overall mark.

Following is a sample of the gallery pictures for Olympus PEN E-PL1s and Pentax K-5 II. The full galleries are available at Olympus E-PL1s Gallery and Pentax K-5 II Gallery.

Often, its hard to envision the difference between sensor dimensions simply by checking specs. The picture underneath will provide you a stronger sense of the sensor dimensions in the E-PL1s and K-5 II.

As you can plainly see, both of the cameras provide different megapixel count and different sensor dimensions. The E-PL1s using its tinier sensor will make getting shallow DOF trickier and the Pentax K-5 II will give you greater detail because of its extra 4 Megapixels. Greater resolution will also make it easier to crop pics more aggressively. The more aged E-PL1s is going to be disadvantaged in sensor tech.
