Olympus E-PL8 vs Pentax K-S1

Below is a comprehensive overview of the Olympus E-PL8 versus Pentax K-S1, one being a Entry-Level Mirrorless and the other is a Advanced DSLR by competitors Olympus and Pentax. The resolution of the E-PL8 (16MP) and the K-S1 (20MP) is very similar but the E-PL8 (Four Thirds) and K-S1 (APS-C) provide different sensor size.

Pentax 17 Pre-Orders Outperform Expectations by a Landslide

The E-PL8 was revealed 2 years later than the K-S1 and that is quite a significant gap as far as tech is concerned. The two cameras feature different body design with the Olympus E-PL8 being a Rangefinder-style mirrorless camera and the Pentax K-S1 being a Mid-size SLR camera.

Before getting right into a in-depth comparison, here is a quick introduction of how the E-PL8 grades against the K-S1 for portability, imaging, features and an overall grade.

Look at the Olympus E-PL8 versus Pentax K-S1 in the new Camera and Lens Size Comparison Tool.

Take into consideration, the weight of an Interchangeable Lens Camera will change based on the lens you are working with at that moment. The following is a front view sizing comparison of the E-PL8 versus the K-S1.

Looking at size and weight, the portability score of the E-PL8 and K-S1 is 86 and 69 respectively.

Usually, its difficult to imagine the difference between sensor measurements just by reviewing specifications. The photograph below should provide you a better sense of the sensor sizing in the E-PL8 and K-S1.

To sum up, both of those cameras come with different megapixels and different sensor measurements. The E-PL8 using its tinier sensor is going to make achieving shallower depth of field more difficult and the Pentax K-S1 will offer you extra detail because of its extra 4 Megapixels. Greater resolution will also allow you to crop images a good deal more aggressively. The more recent E-PL8 provides a benefit when it comes to sensor innovation.
